Garlic clams and garlic are the main products of garlic production. In order to obtain high yields, vegetable growers must pay attention to the top dressing management of garlic sprouts and the growth period of garlic.
One, garlic sprouts stretch fertilizer
Garlic pods grow during the period of top-dressing, which means that they begin to differentiate from garlic cloves and top dressings before convulsions. This period of time is the period when garlic sprouts and garlic grow in parallel, and it is also an important period for the formation of dry matter in garlic. Before and after Ching Ming, garlic entered the period of differentiation of garlic sprouts and garlic cloves. It entered the convulsions period before and after May 1st. In this period, the growth of garlic sprouts overlapped with the early growth of garlic, and it was in a period of vigorous growth. At this time, all the leaves have grown, the growth of the above-ground part of the plant reaches a maximum, and the yield of the underground garlic head has formed close to 50%. The roots begin to expand laterally, and the amount of growth and the absorption of fertilizer gradually reach the peak, so the fertilizer is applied at this stage. The amount should account for about 40% of the total fertilizer. Each acre with high nitrogen and potassium fertilizer 30 kg plus fish protein organic fertilizer 3-4 kg, with water flushing. The use of fish protein liquid organic fertilizer can keep the soil loose, speed up the absorption and utilization of nutrients in the root system, promote garlic convulsions and enlargement of garlic, and obviously increase the yield and quality of garlic sprouts.
Second, garlic growing fertilizer
Before harvesting the garlic bulbs, the growth of the garlic bulbs was mainly to increase the volume. After the garlic bulbs were harvested, the growth of the garlic bulbs was mainly weight gain. The average daily weight gain was about 1 g, and the diameter increased by 0.06 cm. In the growth period of garlic should be mainly available nitrogen fertilizer, with the application of phosphorus and potassium fertilizers. The topdressing amount should account for 25% - 30% of the total top dressing. This period should be topped with high nitrogen, high potassium and low phosphorus fertilizer 20 kg plus fish protein organic fertilizer 3-4 kg.
The method of top dressing of garlic is generally applied in the form of application with water or buried. When chemical fertilizers are applied, they are usually applied by ditching or burrowing, covered with soil, watered, or poured with water, or sprinkled with rain.
Third, foliar fertilizer
Foliar fertilization allows nutrients to enter the plant body from the leaves, and is directly involved in the metabolic process of the plant and the synthesis process of organic matter. The effect is faster than the soil fertilization reaction, and it is an economic and effective fertilization. Farmers can spray 200 times fish protein organic fertilizer solution during the growth period of garlic sprouts, which can reduce the occurrence of maculopathy during the storage and storage of garlic sprouts and improve the quality of garlic sprouts. For foliar spraying, it can also be mixed with fungicides and insecticides at the same time, spraying successively 3-5 times, every 7-10 days.
