What fertilizer is most effective for garlic and what fertilizer is better for garlic

1. Land preparation and fertilization, should choose a sunny and leeward, convenient drainage and irrigation, strong water and fertility retention of fertile fields, remove the residues of the previous crops, timely ploughing and drying, watering the bottom of the water, apply sufficient base fertilizer (5000 8000 kg of high-quality organic fertilizer per mu, 20 30 kg of phosphorus and potassium fertilizer), and keep the furrow surface flat and soft before sowing.

2. Sowing seedlings should be sown in a timely manner, reasonable dense planting, and new high-fat film dressing should be applied before sowing (it can repel underground pests and diseases, isolate virus infection, strengthen seed respiration intensity, and improve seed germination rate), and the suitable depth of general sowing is 3 4 cm. After sowing, water thoroughly, in order to prevent drought, at the same time, spray a new high-fat film 800 times liquid to keep warm and moisture, prevent and control soil slabting, and improve the seedling emergence rate.

3. Field management, timely watering and topdressing according to the growth needs of garlic, weeding in cultivation, timely spraying of strong stems in the growth period, and spraying of strong stems in the growth period, and at the same time, it should also be sprayed in the pregnant stage to make the underground fruit nutrient transport duct thicker, improve the expansion vitality of the fruit, enhance the disease resistance of the plant, and improve the yield of garlic.

4. Pest control, garlic is prone to leaf blight, dry rot, gray mold, virus disease and other diseases during the growth period, according to the requirements of plant protection, targeted agents (such as 20 virus busters, 40% Shijiale suspension, 50% Duofu wettable powder) should be sprayed in time to kill the agent, and at the same time, spray 800 times the new high-lipid film to enhance the efficacy.

What fertilizer is most effective for garlic? Urea.

Garlic prefers organic fertilizers.

Garlic has a long growth period and requires a lot of fertilizer, so it is necessary to master "organic fertilizer, supplemented by chemical fertilizer; Base fertilizer is the main fertilizer, and top dressing is supplemented". The fertilization of garlic is divided into two types: basal fertilizer and top dressing, the base fertilizer is mainly organic fertilizer, and the application rate is directly related to the commerciality of garlic and the overwintering performance of plants. It is generally required to apply 2,500 to 3,000 kg of manure or 4,500 to 5,000 kg of manure.

In spring, when the temperature rises, the heart leaves and roots of garlic begin to grow, and the green manure is returned, and it is advisable to use 15 20 kg of urea per mu.

Garlic differentiation from scale buds and flower buds to sprouting is a parallel period of vegetative growth and reproductive growth, therefore, in addition to nitrogen fertilizer, the sprouting fertilizer should also be combined with phosphorus fertilizer, and nitrogen, phosphorus and potassium three-element compound fertilizer can be applied 20 30 kg. The swelling period of garlic stems is the peak period for nutrient absorption, and the available nitrogen fertilizer should be the main fertilizer, combined with the application of phosphorus and potassium fertilizer. The topdressing should account for 25% to 30% of the total topdressing.

Planting garlic fertilization tips

1. The principle of fertilization

Garlic fertilization should be carried out scientifically and reasonably according to the soil fertility and the needs of different growth periods of garlic, and grasp the fertilization principle of "light before, medium and heavy after supplement", which should not only prevent excessive growth in the early stage, but also avoid early fertilizer and early aging.

2. Soil preparation and fertilization

Before sowing, garlic should be combined with land preparation to apply one-time foot fertilizer, 2500 3000 kg of farm fertilizer, 40 75 kg of chlorine-based compound fertilizer and each kilogram of ferrous sulfate, manganese sulfate, borax, zinc sulfate, and copper sulfate per mu.

3. Apply jointing fertilizer

Garlic in the case of normal climate regreening garlic generally does not carry out field management, top dressing should be placed in the jointing stage, can be 20 25 kg of nitro compound fertilizer per mu, 15 20 days apart and then top the second fertilizer, the amount of application per mu is about 20 kg.

Garlic seedling fertilization includes: farmhouse fertilizer, nitrogen fertilizer, and potassium fertilizer.

1. Farmhouse fertilizer: garlic is good with farmhouse fertilizer, apply 2,500 to 3,000 kilograms of pigsty fertilizer per mu before planting, if you want garlic to grow luxuriantly and produce abundantly, you can apply a sufficient amount of soybean cake fertilizer to the soil, and cooperate with the application of superphosphate, ternary compound fertilizer and other organic fertilizers.

2. Nitrogen fertilizer: garlic is better to apply nitrogen fertilizer, as a perennial herbaceous plant, applying nitrogen fertilizer to it is conducive to the absorption and utilization of nutrients by the root system of the plant, promoting the vigorous growth of garlic, thereby improving the yield of the plant, so it is necessary to apply nitrogen fertilizer-based fertilizer in the growth period, but pay attention to the concentration of fertilizer in the fertilization process.

3. Potassium fertilizer: In the process of cultivating garlic, it is necessary to regularly apply potassium fertilizer to the plant to promote the transportation of photosynthesis and photosynthetic products of garlic, so as to improve the yield and quality of the plant.

Garlic seedling maintenance method

1. Suitable temperature: The best growth environment temperature of garlic seedlings is 18-25 degrees Celsius, and the temperature is suitable in spring and autumn, which is suitable for the growth of garlic seedlings. If it's summer, it's best to keep it indoors to avoid burning the seedlings by the outdoor heat.

In winter, it is also maintained indoors, and the growth temperature can be maintained at more than 15 degrees Celsius.

2. Light conditions: The garlic seedlings grown under different light conditions have different colors and have their own flavors. If it is grown in a shady environment, the color of the garlic seedlings is yellow or tender yellow, and the garlic flavor is relatively small and the taste is fresh.

If it is grown in a sunny environment, the garlic sprouts are green and have a strong garlic flavor. However, in summer, you need to pay attention to shading, and you can't maintain it in direct sunlight.

3. Sufficient water: When maintaining garlic seedlings daily, it is necessary to ensure that the soil is in a slightly moist state, which is conducive to the germination and growth of garlic seedlings.

Usually it is better to use organic fertilizer to apply base fertilizer to garlic, and common organic fertilizers include chicken and duck manure, compost, cake fertilizer, etc., which are conducive to improving the wintering ability of garlic. In addition, if the top application of phosphorus fertilizer and potassium fertilizer to garlic is also better, it can improve the balanced absorption and utilization of nitrogen fertilizer, thereby promoting the growth and development of plants, and improving the yield of garlic sprouts and garlic heads.

Garlic fertilization time.

Fertilizing garlic generally needs to be carried out in early spring every year after the plant recovers its vitality, because at this time the plant grows rapidly and needs sufficient nutrients, so it is necessary to fertilize, in addition, before wintering, regreening, garlic sprout elongation and garlic growth are all required to fertilize.

Garlic shouts cheats Jane what fertilizer to apply.

Usually it is better to use organic fertilizer to apply base fertilizer to garlic, and common organic fertilizers include chicken and duck manure, compost, cake fertilizer, etc., which are conducive to improving the wintering ability of garlic.

In addition, if the top application of phosphorus fertilizer and potassium fertilizer to garlic is also better, it can improve the balanced absorption and utilization of nitrogen fertilizer, thereby promoting the growth and development of plants, and improving the yield of garlic sprouts and garlic heads.

However, in the later stage of garlic, it is necessary to apply nitrogen fertilizer, phosphorus and potassium fertilizer, or compound fertilizer, which can prevent premature leaf senescence in the later stage of garlic and significantly improve the yield of garlic sprouts and garlic heads.

Garlic fertilization method.

If you want to apply basal fertilizer to garlic, then the method of application is to apply half of the organic fertilizer before ploughing the land and spread it evenly on the soil surface, and the other half needs to be applied intensively in furrows at the time of sowing.

If you want to top dressing garlic, you can generally use strip application, water application or buried application and other methods for fertilization, when applying soil miscellaneous fertilizer, you can open a ditch and sprinkle it into strips, if you want to apply chemical fertilizer, you can open a ditch to sprinkle, cover the soil, and water.

Garlic fertilization precautions.

When fertilizing garlic, it is necessary to pay attention to the diligent application of thin fertilizer, and it is best to water after fertilization, and also pay attention to strengthening the cultivation and weeding, and maintain soil looseness and moisture, so as to speed up the absorption and utilization of nutrients by the root system.

Potassium phosphate compound fertilizer is best for garlic:

In the hearts of many people, urea is a universal fertilizer, which can be mixed with organic fertilizer and used as a base fertilizer. We can't deny the value of urea, and this fertilizer is indeed able to provide sufficient nutrients for plants. But in the case of garlic, urea can stunt growth.

Because in the early stages of growth, garlic does not get nutrients from the soil, but from the seeds themselves.

If urea is selected as the base fertilizer, the concentration of the soil will be too high. Seeds have no way to absorb water from the soil and cannot continue to grow. So much so that the seeds fester, and the germination rate of garlic is greatly reduced, which affects the final yield.

In addition to urea, nitrogenous fertilizers should be used with caution. Both ammonium and nitrate nitrogen will absorb water due to high concentrations when they enter the soil. As a result, the seeds of garlic cannot grow normally, and finally the phenomenon of burning seedlings appears.

In view of the uniqueness of garlic growth, scientists have tailored a special fertilizer for it. Therefore, when planting garlic, farmers can choose a special potassium sulfate compound fertilizer. This fertilizer is very comprehensive and can promote the root development of garlic and help garlic sprout.

In the later stage, it can also help garlic grow leaves and promote photosynthesis.

If you feel that it is more costly to buy potassium phosphate compound fertilizer, you can also choose human feces and urine when sprinkling fertilizer. But before spreading fertilizer, it must go through a sufficient decomposition process. Otherwise, it will be like urea, and the garlic will have a serious phenomenon of burning seedlings.

The demand for fertilizers in various stages of cultivation and growth of garlic is different, and three types of fertilizers need to be used to give full play to the fertilizer effect: organic fertilizer, chemical fertilizer, and foliar fertilizer.

1. Organic fertilizer

Organic fertilizer is the basic guarantee for the comprehensive supply of 16 essential nutrients needed for the growth of garlic, and plays an irreplaceable role in the cultivation and growth of garlic.

The loose soil structure is conducive to the germination of roots and the good absorption function, and is also conducive to the development and formation of larger and higher grade bulbs. Organic fertilizer can increase the loose and permeable nature of the soil, and create a good soil environment for root growth, absorption and bulb expansion.

The organic fertilizer applied in garlic cultivation is mainly fully decomposed farmhouse fertilizer, and commercial organic fertilizer with too high salt content should be avoided as much as possible, which can effectively avoid the occurrence of loose cloves or garlic maggots in the later stage of bulb formation, so as to ensure the formation of good quality and yield. However, unrotted organic fertilizer will cause root burning, which seriously threatens the normal growth of garlic and is not suitable for basal fertilizer.

2. Chemical fertilizers

Garlic is a sulfur-loving crop, so nitrogen fertilizer and potassium fertilizer used as base fertilizer or top dressing should be mainly sulfuric acid compound fertilizer, and chlorine-containing fertilizers that will have an adverse effect on the quality of garlic should be avoided as much as possible.

In terms of specific application methods, before overwintering, top dressing can be done without top dressing, or top dressing with a balanced compound fertilizer of nitrogen, phosphorus and potassium can be applied to avoid the application of nitrogen fertilizer alone to cause garlic seedlings to grow, thereby reducing the overwintering performance of garlic. After returning to green in the spring of the following year, a high-nitrogen compound fertilizer should be applied to promote the recovery of garlic growth as soon as possible, and establish a good leaf morphology, laying the foundation for the formation of good yield in the later stage.

At the beginning of the garlic sprouts, the demand for nutrients in garlic reaches the maximum period in a lifetime, and it is necessary to apply about 25kg of high-nitrogen and high-potassium compound fertilizer, on the one hand, to ensure the normal function of the leaves, on the other hand, to lay the foundation for the expansion of garlic sprouts and bulbs.

3. Foliar fertilizer

Foliar fertilizer plays a role in nutritional supplementation for the growth of garlic, and the application period is generally in the middle and late stages of growth, especially in some sandy soils, which are often easy to cause defertilization due to insufficient nutrients in the middle and late stages of growth, thereby affecting the formation of yield, and foliar fertilizer can effectively alleviate the undesirable phenomenon of nutrient deficiency in garlic growth.

Hello dear! Glad to answer for you: what fertilizer is the best fertilizer for garlic Answer: Hello kiss <>

Top dressing at seedling stage: In early spring, after the temperature rises, combined with watering and ditching top dressing, about 20 kg of ammonium sulfate can be applied per mu. Top dressing in the rejuvenation stage:

After the ground temperature rises, combined with the green water, 15 kg of nitrogen fertilizer can be applied with water per mu; Around the beginning of April, it is necessary to reapply a sprout fertilizer, and 15 kg of urea can be applied per mu; In mid to late April, the fertilizer was applied again, mainly nitrogen and potassium fertilizer, and 15 kg of urea and 15 kg of potassium sulfate could be applied per mu. Top dressing at the sprouting stage: In the garlic sprouting stage, fertilizer can be applied once in combination with watering, about 20 kg of nitrogen fertilizer per mu, and an appropriate amount of phosphorus and potassium fertilizer.

Top dressing at bulb swelling stage: Top dressing at bulb swelling stage is mainly to apply bulking fertilizer, which is generally applied when watering for the last time before the garlic sprout is harvested in May, and 10 kg of urea and 5 kg of potassium sulfate can be applied per mu. In order to accelerate the accumulation of organic nutrients and improve the quality of garlic, foliar fertilization should also be paid attention to during this period, and potassium dihydrogen phosphate can be coarsely sprayed with a mixed solution of potassium dihydrogen phosphate + 1% urea, once a week or so, twice in a row.
