How to fertilize and control pests and diseases after chives are planted?

Presumably everyone is no stranger to chives, chives are a more common ingredient in people's lives, and the planting method is relatively simple, now let's take a look at the management technology after the chives are planted!

1. Watering and fertilizing

Seedling plots should be fertilized with organic fertilizers, mainly from animals and humans, and the land should be carefully prepared.

This planting, according to the elongation of the leaf sheath, to implement the cultivation of the soil, the soil to be cultivated is divided under the onion, to prevent the soil from entering the center of the leaf, causing decay, cultivate the soil 2 times, so that the onion can create good growth, high yield, good quality, the cultivation soil can be diluted with water 4 times with decaying human feces, and watered along the stem. If it is applied without water dilution, it is carried out immediately after watering so that the feces seep into the ground.

After planting, since there is no root system, water once a day to ensure the survival of the seedlings, and some root systems will also be produced in about 1 week, which can be watered every three days to encourage the seedlings to take root. After about half a month, the seedlings will grow normally and have a normal root system, so you can watch the soil dry out and water again from time to time. Fertilization should be applied once a month after planting, in conjunction with watering, and once a month thereafter.

Fertilizers should be used mainly to promote the growth of leaves, with fast-acting nitrogen fertilizers, combined with the right amount of phosphorus and potassium. After the green onion seedlings are greened, they should be watered in time and green fertilizer should be applied to promote the early development and rapid growth of the seedlings, and they can be applied with urea or other nitrogen fertilizers with comparable nutrients.

2.Eliminate pests and diseases

Clean the countryside and eliminate the source of insects. Before planting and after harvesting, the residual leaves and dead leaves in the field should be removed in time, and the field should be burned and buried deeply, and deep ploughing and winter irrigation should be carried out to eliminate the source of overwintering insects.

Pesticide control should be seized in the peak period of adult oviposition or the period when the spraying effect is best in the early stage of larval hatching, and kill the adults and eggs.

Fertilization to repel flies, green onion flies are satrivorous, and farm fertilizers such as various manure and cake fertilizer applied to the field must be fully decomposed to reduce the aggregation of pests.

Pest control should grasp the principle of prevention and comprehensive management, adopt agricultural and biological control measures, scientifically use chemical pesticides, and coordinate various control technologies in order to give full play to the comprehensive benefits, in addition to increasing the application of organic fertilizer, timely watering and top dressing, but also pay attention to the supplement of phosphorus and potassium fertilizer, not only nitrogen fertilizer, but also to raise stubble.

Pay attention to the surrounding weeds, you need to clean up the weeds, pay attention to cleanliness and hygiene, you can spray pesticides, you must pay attention to the watering, pay attention to the fertilization, you must be reasonable, and fertilize according to the proportion.

Be sure to choose the right time for fertilization, do not use fertilizer when the temperature is relatively high, the rain is relatively heavy, and the wind is relatively strong, and the right medicine should be prescribed according to the diseases and insects that appear in the crops, and the concentration should be paid attention to.

After planting, you can sprinkle some pesticides on the soil, and you can also sprinkle some herbicides, so that you can control pests and diseases, and you can prevent the breeding of pests and diseases.

You can fertilize and spray in good weather, so the effect will be better.

Shallots can be grown all year round, but mainly in spring and autumn. In summer, cover plastic shade nets for sowing seedlings and transplanting, or intercropping with tall crops; In winter, it can also be transplanted to small arch sheds and large and medium sheds to achieve annual balance**. The seeds of allium plants can be sown or propagated by ramets, usually by ramets.

Shallots are not suitable for long-term continuous cropping. After 3 to 4 years of cultivation, the leaves become shorter, the tillers of the plant clusters decrease, and the yield decreases. Select the soil that has not been planted with onion and garlic vegetables for 2 to 3 years, plough the pre-drying crops immediately after harvesting, sow and transplant after raking, and continue to cultivate acidic soil.

Microbial agents and mineral potassium fulvic acid are applied per mu to prevent and control diseases and regulate acidic soil. It is necessary to apply sufficient base fertilizer and sprinkle well-rotted chicken manure and pig manure per mu.

The amount of nitrogen fertilizer and potassium fertilizer required in the growth process of shallots is basically the same, so on the basis of increasing organic fertilizer, the amount of potassium fertilizer should be increased, and the amount of shallots per mu should not be less than 25 kg per season. At the same time, due to the fluidity of potash fertilizer, the dosage per mu should not exceed 10 kg each time. In order to promote the normal growth of shallots, trace element foliar fertilizer should be sprayed on the leaves to meet the growth and development of shallots.

The root system of shallots is underdeveloped, shallowly distributed, and is not tolerant to drought and waterlogging. According to the soil moisture and seedling conditions, timely irrigation and watering are necessary. In water management, frequent watering is required to keep the soil moist.

At the same time, attention should be paid to digging ditches and draining water to prevent root and bulb rot and cause dead seedlings. Because the root system of leeks has a weak ability to absorb water, it is necessary to insist on frequent irrigation with a small amount of water in times of drought to prevent drought and flooding.

On sunny days from May to October, you should be watered every morning and evening. In summer, the temperature is high at noon, and the temperature difference between water and soil is large. Watering at this time is not only easy to burn dead onions, but also easy to induce many diseases.

Irrigation and watering should be avoided to avoid physiological discomfort with shallots. The purpose of water management during the growing period of shallots is to keep the soil moist but not to be flooded. The root system of shallots is underdeveloped, mainly grows on the surface, and has poor fertilizer and water tolerance.

The soil is too dry and wet, and it is difficult to water with large amounts of water when watering in dry weather, and it needs to be watered with very little water. After slowing the seedlings, an appropriate amount of urea can be applied every 20 days before watering or rain. After watering, foliar spraying of special vegetable Zhuangganling or special foliar fertilizer for preventing leek dry tips can promote the vigorous growth of shallots, thicker stems, thicker and greener leaves, and improve the overall resistance of plants to pests and diseases.

When we plant shallots, we generally choose to fertilize it in rainy weather, because in this way, the fertilizer is easy to melt, and the shallots can be absorbed well, so that the yield of chives will be improved.

The root system of chives is not developed, mainly grows in the surface layer, the endurance of fertilizer and water is very poor, the soil is too dry, too wet is not good, it is not easy to water in dry weather, and it needs to be watered with small water frequently. After slowing the seedlings, you can apply an appropriate amount of urea before watering or rain, once every 20 days, after watering, the foliar spray of vegetables special strong stem spirit or leeks special anti-drying tip foliar fertilizer, can promote the growth of chives, thicker stems, thick and green leaves, but also improve the overall resistance of the plant to diseases and pests, but stop fertilization half a month before harvest.

Potash and nitrogen fertilizers. Choose flat, loose, fertile, well-drained and watered fields for transplanting fields, and it is best to rotate with soybeans, corn and other vegetables, not with onions and garlic. 2000 kg of high-quality organic fertilizer and 50-70 kg of ternary compound fertilizer are sprinkled per mu, and the land is finely prepared, and the high furrow is made of rice width, and the ground temperature can be increased by covering the plastic film in winter, so that one more stubble can be harvested.

In the process of planting green onions, in fact, it is best to avoid reducing the use of chemical fertilizers, especially urea, urea belongs to the chemical fertilizer category, a strong fertilizer, once the ratio is improper, the concentration is too high, it is easy to burn the root system. If it is sprayed as foliar fertilizer, in hot weatherIn addition to greenhouse planting, green onions planted in the natural environment can be planted in spring, summer and autumn in addition to winter can not be planted. Generally, spring planting can be sown after the soil thaws; The planting in summer (because it belongs to Futian in summer) is called Futian, which shows that the amount of urea fertilizer application is still relatively strict.

So for green onions, it is an important crop that my family must raise and transplant seedlings every year, and we just carried out weeding work a few days ago.

<> elongation of leaf sheath cells of the pseudostem of green onions requires a dark and moist environment and is based on the input and accumulation of nutrients. Soil cultivation is an important measure to prevent lodging, soften leaf sheaths, prolong the length of green onions, and improve the yield and quality of green onions. The type and quantity of fertilizer used in green onions have a great impact on their growth and development, yield and quality.

Among them, nitrogen is an important factor in determining the yield of green onions, phosphorus affects the occurrence and growth of green onion roots, and potassium is mainly involved in photosynthesis and the transport of photosynthetic products.

All crops and vegetables are dependent on nitrogen, phosphorus and potassium. But different plants have different needs for various elements. The amount of nitrogen absorbed by green onions is more than that of potassium during the peak growth period, and the ratio of nitrogen to potassium is about; Entering the fullness period of onion stems, the absorption of potassium increases, and then shallow tillage and fine rakeing, 50kg of compound fertilizer can be applied per mu as base fertilizer, and at the same time, it can be applied to frandan, carbendazim powder to kill underground pests and bacteria.

Green onions in the beginning of autumn topdressing, per mu to apply 3000-4000 kg of soil fertilizer or cake fertilizer 150-200 kg, can also apply urea 10-15 kg.

In general, the amount and method of fertilization need to be adjusted depending on the variety. For long white onions such as Zhangqiu green onions and Chinese giant green onions, sufficient amount of decomposed organic fertilizer should be applied in the planting ditch, but chicken manure should not be applied. And increase the application of phosphorus and potassium fertilizer, generally apply 30oo-50oo kg of rotting organic fertilizer per mu.

After planting, the green onion seedlings grow slowly, when the rainy season passes, the weather gradually cools, the green onion plants enter the vigorous growth period, the old leaves gradually wither yellow, and new leaves continue to occur. In good nutritional status and dark conditions, it can promote the growth of multiple leaves and leaf sheaths. Immediately after the beginning of autumn, top dressing, and to master the combination of organic fertilizer and fast-acting fertilizer.

For each top dressing, apply 4000kg of soil miscellaneous fertilizer on the back of the ridge every 667 square meters, or apply 150kg of cake fertilizer or 3000kg of kang cave soil, and then apply shallow hoeing 1 time and watering 1 time.

Fertilization of green onions, application of farmhouse fertilizer per mu of base fertilizer, use of high-efficiency nitrogen fertilizer, and watering can play a good role in promoting rooting and growth; After that, topdressing needs to be supplemented with farm fertilizer, urea or cake fertilizer in time to ensure the healthy growth of crops; When the green onion white enters the swelling and peak production period, it is necessary to appropriately increase the use of phosphorus and potassium fertilizers.

Fertilizer should be applied in moderation, not too much fertilizer, otherwise it will affect the growth of the deposit.

What fertilizer is good for green onion fertilization? How to fertilize green onions for high yield?

The onion planting seeds must be separated from the seeds at a slight distance, and if you want to get a slightly larger onion, you can open the spacing slightly. Allowing the onion to grow and develop sufficiently, over-concentrated cultivation will cause the onion to compete for nutrients in the middle. The second point is to fertilize the development of onions.

Fertilization should be based on the actual growth and development of onions. Generally speaking, you will apply basal fertilizer to the soil layer before planting, and fill the soil layer with nutrients, which can make the onion rise more abundantly. If we had applied basal fertilizer before planting onions, we <>

You can reduce the frequency of fertilization without continuing to fertilize. Generally speaking, you will apply basal fertilizer to the soil layer before planting, and fill the soil layer with nutrients, which can make the onion rise more abundantly. If we have already applied basal fertilizer before planting onions, we can reduce the frequency of fertilization without continuing to fertilize.

Until the onion fruiting stage, then it is necessary to carry out the first flight immediately, preferably in the case of the onion stem gradually growing, in fact, it is the onion conclusion stage, and there must be a lot of nutrients at this moment.

In the case of fertilization, it should be evenly sprinkled in the middle of each seedling, and after fertilization, it is also necessary to carry out rotating land resources, so that the fertilizer can be easily digested and absorbed by the onion, and it is also necessary to cooperate with each other after each fertilization. It is best to use some manure and urine water, mixed with a little basal fertilizer to water, which can make the seedlings grow faster. Because the growth and development of onion seedlings are very slow, we need to apply pre-seedling fertilizer.

The key to pre-seedling fertilizer is to be dominated by soil miscellaneous fertilizer, and add three or four catties of phosphorus and potassium fertilizer, which should be evenly sprinkled in the seedling field, and turned over and mixed in the burial. I <> until after the onion planting

We should carry out fertilization in combination with water release, and the key is to carry out irrigation with a little quick-acting base fertilizer with manure and urine water to promote the development and growth of seedlings. The key is to be dominated by phosphorus and potassium fertilizers and potassium fertilizers, which can promote the growth and development of part of the upright stems and roots of onions. If you want to plant at home, people only need to pay attention to the following aspects, usually in July.

Good friends in the south can plant a little later in August. There is not much difference between the planting method and other cultivation. Naturally, it is important to note that the top must be bent before the first frost falls.

To grasp the time of fertilization, but also pay attention to the number of fertilization, you can choose to fertilize two weeks after planting. Be sure to water in time to ensure the moisture of the soil.

Fertilization is mainly carried out according to the growth of plants, and fertilization must pay attention to the condition of the soil and pay attention to safety issues.

When fertilizing, you can dig a trench next to it to fertilize, or you can apply fertilizer by watering. It is necessary to pay attention to the frequency of equipment, the amount of fertilizer, the proportion of drinking water, the method of fertilization, and the protection of individuals.

In the process of chives planting, no pesticides are used to control pests and diseases, and the occurrence of pests and diseases needs to be prevented from before planting and during the growth process. First of all, from the soil and seeds at the source to prevent the planting of germs and insect eggs with sowing, do a good job in the prevention and control of pests and diseases before sowing. Like onions, it can be propagated mainly by planting shallots.

Each shallot can have 4-7 seedlings. After aging in summer every year, planed out and braided into braids and hung to dry, can be planted in early autumn, using strip planting, winter can be open to winter but the most suitable temperature for growth, is between 19 and 24 degrees, when the temperature is above 28 degrees or below 11 degrees, the chives will grow very slowly, and when they enter the summer when the temperature is very high, they will enter a dormant state, and the root system of the chives is very shallow.

<> we can use some farm manure to control pests and diseases, and we can also obtain high-quality and high-yield chives, such as chickens, sheep, pigs, manure, and soil stove ash can achieve the role of controlling pests and diseases to obtain high quality and high yield. Spread evenly on top of the chives soil ridge by fermentation. After that, it's time to plant the chives.

This can reduce some pests and diseases. Second, you can use the oil dry at home (camellia seeds, after squeezing the oil, the remaining waste), spread it and mix it with hot water, and choose disease-resistant seeds. Generally, disease-resistant varieties such as Binchuan shallots, purple shallots, and Yongsheng shallots are selected.

Reasonable crop rotation and intercropping. In order to prevent the occurrence and spread of viral diseases, crop rotation is promoted in production. Chive planting area should be rotated with non-onion and garlic crops for 2 3 years White rot mainly occurs in late spring and early summer, during this time there is more rain, coupled with the temperature is slowly rising, so it is easy to produce sclerotinia virus, slowly infect the rhizomes of chives, resulting in the leaf surface of chives slowly turning yellow and wilting, and some white mycelium grows on the roots according to the growth of the field, selective fertilization and irrigation.

Tiller fertilizer: apply 10kg of urea per mu and 20kg of compound fertilizer. Bulking Fat:

At the bulb expansion stage, 25kg of potassium sulfate compound fertilizer was applied per muThe use of fast-acting nitrogen fertilizer is prohibited 30 days before receipt.
