Key points of planting techniques of garlic

Garlic was introduced into China from the Western regions in the Qin and Han dynasties. After artificial cultivation and breeding, garlic has the effect of anti-cancer and is loved by the public. Garlic has strong growth, strong cold tolerance, high bolting rate and storage resistance, so it is suitable for planting in autumn. I. growth habits

Garlic is a string-shaped whisker root; the ability to absorb water and fertilizer is weak, and the bulb grows and expands in the soil, so garlic should be cultivated in fields with loose soil, good drainage and rich organic matter. Although garlic has great adaptability, it is better to use sandy loam. Because the sandy loam soil is loose, suitable for root development, turn green early, bolting early, garlic is big and spicy, and it is easy to start garlic.

1. Temperature: like cold and cool, the suitable temperature is-5-26 ℃. Garlic seedlings have the strongest cold tolerance at 4-5 leaf stage, which is the most suitable for overwintering Miaoling.

2.Illumination: the garlic that finished the spring flower began to differentiate the flower bud and scale bud under the condition of more than 13 hours of long sunshine and higher temperature, and was only suitable for stem and leaf growth in the short-day and cool environment.

3. Moisture: like dampness and fear drought

4. Soil and nutrition: the requirement of soil is not strict, but the fertile loam which is rich in organic matter, loose and permeable, strong water retention and drainage is more suitable. Second, planting preparation

Plots growing garlic should be ploughed and dried immediately after the previous crop is harvested, and the land should be prepared before sowing. Base fertilizer should be applied before ploughing. Garlic because of its long growth period, high population density and large amount of fertilizer, the general application of high-quality organic fertilizer such as manure, manure, barnyard manure and so on 50008000kg; and with 20kg 30kg phosphorus and potash fertilizer. Organic fertilizer should be fully mature, if raw fertilizer is used, garlic root will be burned during fermentation, and it will also cause underground insect pests, especially the serious occurrence of maggots.

1. Land preparation. Ploughing depth is generally about 20cm, to fine ploughing, raking flat, raking solid, there is no obvious bumpy, to achieve "neat, loose, broken, clean". According to the water source, the length of the border can be 80-100m long and 4.2-4.4m wide, and that of 40m-50m long and 4.2-4.4m wide.

2. Seed selection. Peel and break the peel manually, remove the trays and stem plates of garlic, and grade them according to large, medium, small and garlic hearts. according to the specific conditions, the seed selection requirements of small garlic cloves are pure white without red tendons, no scars, no saccharification and no bare skin. The principle requires that each grain weighs about 5g. Seed size is the key to high yield.

3. sow seeds at the right time. Garlic should be sown at the right time. The planting time is at the end of Bailu and the beginning of the Autumn Equinox (late September and early October), and the temperature is about 17 ℃. The garlic cloves should be dried for 1-2 days before sowing.

4. Reasonable close planting. General row spacing 20cm, plant spacing 16~17cm, about 20 000 plants per 667m2. The method is to use a rake or trench opener to open the ditch, the ditch depth is about 5cm, cover the soil above the garlic about 1cm after planting, and remember to water when planting.
