How do you need to fertilize garlic seedlings? When is fertilization more effective?

The best fertilization effect of planting garlic seedlings is to sprinkle a layer of phosphate fertilizer under the garlic grains when they are just planted, and then use farmhouse fertilizer to water them when they grow to a height of 12-15 cm, and the garlic sprouts that grow are thicker.

Garlic is not planted in autumn, and spring sowing is generally used, and spring sowing is generally used in the Northeast. The planting is usually done in April. In Sichuan and Guizhou, sowing is usually carried out in August.

Therefore, growers should plant according to local conditions. The sowing time of garlic is generally determined according to the local weather temperature, in places with relatively high temperatures, such as Sichuan, Guangzhou and other places, sowing garlic in autumn, the more garlic can be safe, and it can be harvested in the early summer of the second year. But in the place where the temperature is very low in winter, garlic likes cold and cool climatic conditions, the suitable temperature for the growth of stems and leaves on the ground is 12-16, and the best seedling age for seedling overwintering is 4-6 leaf stage, it takes about 40-45 days from sowing to 4-6 leaves, and the growth stops below the average daily temperature of 7.

Seedlings are hardy and can tolerate low temperatures of -7 -10.

<> traditional planting method: First of all, use a hoe, dig an eight-inch wide ditch bottom, put organic fertilizer, put garlic seeds on both sides of the bottom of the ditch, and cover a layer of fertile soil, in the process of mulching, five minutes thick soil can be, the soil is thick, garlic raw garlic is usually sown in mid-March and late April, mid-September and mid-October, when garlic is sown, the surface temperature is 12 20 The most suitable germination. Affected by the regional climate, spring sowing in the south can be advanced to early March, and autumn sowing can be postponed to October

The large cloves of garlic are suitable for sparse sowing, and the small cloves of garlic are suitable for dense sowing; It is suitable for sparse sowing with open leaf shape, and dense sowing is suitable for dense sowing with compact and upright leaf shape. The fertile field is suitable for sparse sowing, and the field is poor and suitable for dense sowing; There are two kinds of garlic with large cloves and small cloves, the spicy taste is lighter, it is cold-resistant than purple garlic, it is sown in autumn, and the maturity period is slightly earlier. Under the cold and cool climate conditions of garlic planting, the suitable temperature for the growth of above-ground stems and leaves is 12-16, and the optimal seedling age for overwintering is 4-6 leaves.

Generally speaking, the garlic planting season is around September to early October in the solar calendar, and the temperature between night and day is best between 5 degrees and 25 degrees, and it is best to plant garlic at this time. After garlic is planted, it can be fertilized with chemical fertilizers or artificial fertilizers.

Hello! I've received your question! Wait a minute, I'll sort it out for you!

The planting time of garlic is generally in winter, and the base fertilizer should be applied before planting to ensure that the base fertilizer is sufficient. The basal fertilizer is best organic fertilizer, half of which is evenly sprinkled on the soil surface before ploughing, and the other half is mixed evenly with the soil at the time of sowing before sowing. Top dressing should be carried out at the jointing stage to ensure that the garlic can grow normally.

After it starts to moss, it is the most important stage of fertilization, so pay special attention. In addition, you can also spray some foliar fertilizer at the right time to help it grow.

Hope mine is helpful to you.

Heart] [heart] question: I planted it on October 1st, I didn't apply base fertilizer, and now I have 4 or 5 leaves, can I apply fertilizer?

You can fertilize it! But not too much.

Fertilization is best when pumping moss.

Hee-hee] [hee-hee].

Question: Diammonium and potash.

I'm afraid it won't be good for the winter.

Garlic is generally planted in a "double film covering" mode for the winter, and the first film mulching is carried out at the time of cultivation. The second mulching is carried out before wintering, usually after the heavy snow season, or according to the forecast of the meteorological department, when the average temperature drops below zero degrees Celsius, and the aboveground part of the garlic has been dormant and has stopped growing. When mulching, it should be noted that the soil on both sides of the film should be pressed well, and not too tight, so as to give garlic seedlings a suitable space.

Generally, in early March of the following year, the membrane is removed.

Garlic sowing is generally in autumn, late September to mid-October, when the garlic seedlings grow to about 10 15 cm and grow 3 5 new leaves, top dressing begins, chasing once every 15 20 days, chasing 3 5 times in a row.

The growth period of spring-sown garlic, especially the seedling growth period, is significantly shorter than that of autumn-sown garlic, so it should be sown as early as possible to meet the requirements of low temperature in the vernalization process, so that the garlic can be mossed and divided. If the spring sowing is too late, it will inevitably affect the formation of products and reduce the output. The suitable sowing date for autumn sown garlic in the open field in the north is from late September to early October.

Spring sowing is carried out in Northeast China, North China, Inner Mongolia and high-altitude areas, and after the local soil thaws, the average temperature is stable above 5. Generally, garlic grows rapidly after regaining vitality in early spring, at this time, it is necessary to pay close attention to fertilization, and it is advisable to apply all-element compound fertilizer, not nitrogen fertilizer or phosphorus and potassium fertilizer alone. Generally, the method of watering combined with watering is used to fertilize, and the temperature is relatively low at this time, and the phenomenon of burning garlic due to fertilizer transpiration will not occur.

After beating the garlic moss, it is necessary to apply a fertilizer based on phosphorus and potassium fertilizer, and the fertilization method is the same as above. Organic fertilizer can also be applied on top of these two fertilizations, so that the garlic produced is a green food.

1. Garlic seedling fertilization is divided into the base fertilizer of the cultivation period and the top dressing of the later growth, the base fertilizer can be combined with land preparation, and the top dressing needs to be topdressed at least twice, and the amount of fertilizer can be increased or decreased according to the growth of garlic seedlings at other times.

2. During the growth period of garlic seedling cultivation, less fertilizer is required, but the planting density of the plant is large, and the amount of fertilizer absorbed per unit area is more. At the same time, smaller garlic cloves are mostly used for garlic seedling cultivation, and the nutrients provided by the mother cloves are less, so the soil needs more fertilizer. In addition, the edible part is a false stem (that is, the leaf sheath part, also called garlic white) and young leaves, which requires garlic seedlings to be tender and juicy, and delicious, so the cultivation and fertilization of garlic seedlings cannot be ignored.

3. Garlic seedling cultivation and fertilization is to apply sufficient base fertilizer, and the second is not to squat seedlings, but to promote to the end. The base fertilizer can be combined with land preparation, 667 square meters of 4000-5000 kg of rotting circle fertilizer, or 2500-3000 kg of human and animal manure, or 5000 kg of farm fertilizer, 15-20 kg of ammonium bicarbonate, 50 kg of superphosphate as base fertilizer.

4. Garlic seedlings are generally topdressed 2-3 times, with fast-acting fertilizer as appropriate, and nitrogen fertilizer as the main fertilizer. The first top dressing, generally carried out after the seedlings emerge, 667 square meters of rotting mature manure 1000-1500 kg, or urea 10-15 kg; The second top dressing can be done about 15 days before harvest and can be applied at the same rate as the first. If the harvest is late, you can add a top dressing between two top dressing, and the number of top dressing is generally 667 square meters, and 15-20 kg of urea is applied.

Harvested after spring, it is necessary to combine watering and applying green fertilizer to accelerate the return to green and improve the quality and yield of garlic seedlings. To cultivate garlic seedlings in a greenhouse, it is necessary to prepare fertile soil for cultivation. Top dressing is mainly carried out by foliar surface for extra-root top dressing.

After the seedling height is 5 cm, 20 grams of urea water per square meter are watered, and 300 times of the aqueous diammonium phosphate solution is sprayed every 7 days.

Although garlic seedlings have seed petal nutrition during the growth period, in order to promote the growth of seedlings and increase the vegetative area of plants, they should still be topdressed at an appropriate time. Due to the weak ability of garlic roots to absorb water and fertilizer, fast-acting fertilizer should be applied to top dressing to avoid yellowing of leaf tips due to defertilization. Garlic top dressing is generally 3 to 4 times.

Seedling fertilizer during the period of garlic topdressing.

After the garlic seedlings emerge, apply a light human feces to extract the seedlings, and avoid applying ammonium carbonate to prevent burns to the seedlings.

The period of garlic topdressing is full of fertilizer.

After sowing for 60 to 80 days, reapply a rotting manure and animal fertilizer plus chemical fertilizer, 1000 1500 kg of manure per mu, 10 kg of ammonium sulfate, and 5 kg of potassium sulfate or potassium chloride. To achieve early maturing varieties early chasing, medium and late maturing varieties late chasing, in order to promote the growth of seedlings vigorous, stems and leaves stout, to rot the mother less yellow tip or no yellow tip.

Pregnant sprout fertilizer during the period of garlic top dressing.

After planting garlic rotten mother, flower buds and scale buds gradually differentiated into the flower stem elongation stage. At this stage, the old roots are senescent, the new roots occur in large quantities, and the stems and leaves and garlic sprouts are also rapidly elongated, and the garlic head also begins to expand slowly, so it needs more nutrients, and the available potassium and nitrogen fertilizer (compound fertilizer is better) 10 15 kg should be reapplied. It is applied about half a month before the end of the current tail (the seedlings can be peeled and the short sprouts in the lower part of the false stem can be observed) to meet the needs and promote the rapid and vigorous growth of garlic sprouts.

The requirements for garlic seedlings are not strict, and the early-maturing varieties with strong disease resistance and stress resistance, short growth period, wide and soft leaves, high quality and high yield are the main varieties, so that the garlic seedlings grow are thick and high-yielding. Before planting, the soil should be selected in loose and fertile, flat terrain and well-drained plots, which is conducive to improving yield.

Garlic seedlings for sowing should be selected with neat garlic cloves, no disease spots and no damage to the garlic head, and the garlic head should be disinfected before sowing, which can not only eliminate the bacteria on the garlic head and reduce the probability of disease, but also promote the rapid germination of garlic seedlings. When planting, you can sprinkle the garlic cloves into the hoe ditch, plant them reasonably densely according to the spacing, and cover the soil with your hands while sowing to prevent the garlic cloves from falling down.

It is better to choose human feces and urine.

Garlic is one of the vegetables that need more fertilizer and is more resistant to fertilizer, so we must pay attention to the details when fertilizing garlic, so as to achieve scientific fertilization. Due to the shallow root system of garlic, few root hairs, shallow distribution, and poor fertilizer absorption ability. It likes moisture, fertilizer and fertilizer during growth.

It is suitable for slightly acidic sandy soil with deep soil layer and rich organic matter. Garlic is afraid of alkali, does not like clay, alkaline cultivation, the mother petal is perishable and easy to incur garlic maggot harm, and the seedlings are yellow and weak, and the false stem lodging when returning to alkali. Therefore, when fertilizing, you need to pay attention to what kind of fertilizer is used.

Human feces. Human manure is the most used farm fertilizer in rural areas for thousands of years, and it can be applied to basically any crop, so garlic is no exception. Human manure is a fast-acting fertilizer, the fertilizer effect is fast, can be quickly absorbed and utilized by garlic plants, can be used as base fertilizer and top dressing, can also take the clarification solution for foliar spraying.

Human feces contain many minerals needed by garlic, so it is very suitable for use as fertilizer for plants, and most of the nutrients needed by plants can be obtained from human feces.

Human feces and urine contain a lot of trace elements and medium elements, as well as insect eggs and various pathogenic bacteria that are harmful to plants, and if they are not decomposed, they will increase the probability of pests and diseases. If human feces and urine are not decomposed, they will also be fermented after being applied to farmland, resulting in burning roots and leaves, often causing lack of seedlings and broken walls, affecting the normal growth and development of crops. Therefore, when applying human feces, it should be decomposed first and then diluted, in order to prevent the roots from burning and making the garlic unable to survive.

After dilution, it needs to be fertilized, and the amount and time should be controlled when fertilizing.

1. Rejuvenation.

After the year of garlic, from the beginning of the rejuvenation period, into the scale bud and flower bud differentiation stage, the growth of the ground and underground accelerated, the nutrients in the garlic mother have been depleted by the plant, and the temperature was low at that time, the soil microbial activity weakened, the soil nutrient release ability was not strong, in this case, the supply and demand of nutrients were unbalanced, and the garlic leaves had a yellow-tip phenomenon, and the growth was stagnant. This occurs during what should be a rapid growth phase, affecting plant growth, and the longer it lasts, the greater the impact. Therefore, it is necessary to chase back the green manure as early as possible in the rejuvenation period.

Top dressing time is generally carried out in early and mid-March, when the temperature is stable at about 6 7 degrees, combined with watering. The use of fertilizer varieties depends on whether the bottom fertilizer is applied sufficiently and the garlic seedlings grow. Generally, the base fertilizer is sufficient, the combination of nitrogen, phosphorus and potassium is reasonable, the garlic seedlings grow robustly, the leaves have no yellow tips, and the three-element compound fertilizer is 20 30 kg per mu.

The bottom fertilizer is insufficient, the leaves have yellow tips, 20 25 kg of urea per mu, or 40 50 kg of high-nitrogen compound fertilizer. Fertilizer is better to be fertilized by ditching, and through watering, it can be achieved to adjust fertilizer with water, promote absorption, and quickly restore the growth of new roots and new leaves.

Second, the garlic moss elongation period.

The garlic sprouting stage is the period when the vegetative growth and reproductive growth of garlic go hand in hand, with the largest growth and all the leaves growing. A large amount of nutrients need to be supplemented to meet the needs of stem and leaf growth and sprouting, and fertilization must be complete and sufficient nutrients. Generally in early April, when the garlic is in the garlic sprout gestation period, the fertilizer is mainly phosphate fertilizer and potassium fertilizer, supplemented by nitrogen fertilizer, and can also be topdressed with 35 kg of low nitrogen, high phosphorus and potassium three-element compound fertilizer or about 200 kg of organic fertilizer.

This fertilization not only promotes the growth of stems and leaves and garlic moss, but also promotes the gradual expansion of the growing bulbs.

3. Garlic swelling period.

Garlic bulb expansion period, is the key period of garlic yield formation, but also the stem and leaf synthesis of the most organic matter period, due to the bulb growth is large, the growth time is short, so we must seize the critical period for top dressing, neither too early, nor too late, generally in garlic after 2 days after the top dressing, can not delay the time, fertilization combined with watering. Attention should be paid to the topdressing of nitrogen fertilizer and potassium fertilizer, combined with the application of a small amount of phosphate fertilizer. , 20 30 kg of three-element compound fertilizer per mu.

It can promote the rapid expansion of garlic and lay a good foundation for obtaining excellent and high yield.
