Early garlic time:
The yield of early-maturing garlic is lower than that of ordinary garlic, but the growth period is very short, belonging to very early-maturing garlic varieties, and the growth period is about 3 months.
The local garlic planting time is from early August to late August, from late February of 165438 to early February of165438, and garlic can be harvested in the first half of February next year.
After the rice is harvested, don't delay, plant garlic immediately, so that garlic shoots can be listed during the Spring Festival.
Training points:
Generally, the sowing depth of garlic is 3 ~ 4 cm. One is planting, that is, inserting seed petals into the soil and covering the soil after sowing, and the other is ditching and sowing, that is, digging a shallow ditch with a hoe and sowing seed petals in the soil.
After a ditch is opened, the soil opened at the same time covers the first row of seed petals. After sowing, the soil thickness is about 2 cm, and the feet are slightly practical, so water them. In order to prevent drought, you can cover the soil with two layers of straw or other moisturizing materials.
Planting should not be too deep, which will lead to late emergence, too long pseudostems, too much water-absorbing fertilizer in the roots and too fast growth, and it is difficult for garlic to expand when squeezed by soil.
However, the planting should not be too shallow. If it is too shallow, it is easy to "jump" when seedlings emerge, the rhizosphere is easy to lack water at seedling stage, the root system is underdeveloped, and it is easy to freeze to death in winter.
On-site management:
Although there is petal nutrition in the growth period of garlic seedlings, topdressing should be timely in order to promote the growth of seedlings and increase the vegetative area of plants.
Because the root system of garlic is weak in absorbing water and fertilizer, quick-acting fertilizer should be applied to prevent the tip of garlic from yellowing.
Topdressing:
Seedling-promoting fertilizer: When garlic seedlings are fully grown, apply 1 times of light human manure to raise seedlings, and avoid applying ammonium bicarbonate to prevent seedlings from burning.
Filling fertilizer: after 60-80 days of sowing, apply decomposed human and animal fertilizer and chemical fertilizer 1 times, 20-30 loads per mu, ammonium sulfate 10 kg, and 5 kg of potassium sulfate or potassium chloride.
Early-maturing varieties should be driven early, and late-maturing varieties should be driven late to promote the vigorous growth of seedlings, strong stems and leaves, and few or no yellow shoots.
Fertility: After planting garlic, flower buds and scale buds gradually differentiate into flower stem elongation period. During this period, the old roots are aging and a large number of new roots appear. At the same time, the stems, leaves and garlic bolts are also rapidly elongated, and garlic begins to swell slowly and needs more nutrients, so it is necessary to use available potassium and nitrogen fertilizers for re-application.
(compound fertilizer is better) 10 ~ 15 kg.
Apply it about half a month before the end (you can peel the seedlings and observe the short stems under the false stems) to meet the needs and promote the rapid and vigorous growth of garlic bolts.
Garlic swelling fertilizer: early-maturing and early-middle-maturing varieties, because the temperature is not high when garlic is swollen; Garlic swelling period is relatively long, in order to promote garlic hypertrophy, it is necessary to topdressing available nitrogen and potassium fertilizer before garlic bolting.
