How to manage the garlic field? Garlic field management technology

1, garlic field topdressing

Although the garlic seedlings have a kind of petal nutrition in the growth period, in order to promote the growth of the seedlings and increase the nutrient area of ​​the plants, the fertilizer should be applied at a proper time. Because the garlic roots have weak ability to absorb water and fertilizer, the topdressing fertilizer should be applied with quick-acting fertilizer to avoid yellowing of the tip of the leaf. Garlic topdressing is generally 3-4 times, divided into:

Promote seedling fertilizer: After the garlic is out of the seedlings, apply 1 time of clearing the water to raise the seedlings, avoid applying ammonium bicarbonate to prevent burns of the seedlings.

Sheng Changfei: After 60-80 days of sowing, re-apply 1 time of decomposed clear manure water + urea, 20-30 ounces per acre. Early-maturing varieties are chased early, and late-maturing varieties are lately chased, which promotes the growth of young seedlings, thick stems and leaves, and less yellow tips or yellow tips when rotten mothers.

Pregnancy and fat: After the garlic is smashed, the flower buds and buds gradually differentiate into the flower stem elongation period. In this period, the old roots are aging, and new roots occur in large numbers. At the same time, the stems and leaves and garlic stalks also rapidly elongate, and the garlic begins to slowly expand, so it needs more nutrients and 10-15 kg of compound fertilizer. It is applied in the first half of the month before the end of the tail (the short stalks in the lower part of the pseudo-stem can be observed in the peeling seedlings) to meet the needs, and the garlic stalks are quickly and vigorously grown.

The garlic is swollen and fat: early maturing and early-maturing varieties, the temperature is not high when the garlic is inflated; the garlic expansion period is correspondingly longer. In order to promote the garlic head hypertrophy, it is necessary to apply the quick-acting nitrogen and potassium fertilizer before harvesting the garlic. Such as: nitrogen and potassium compound fertilizer application 5-10 kg, if the application of urea, 5 kg or so can not be applied too much, otherwise it will cause the formed garlic cloves to return to green, and then re-long leaves and consume the garlic clove nutrients . Topdressing should be carried out before harvesting garlic. When the garlic is harvested, it has rich nutrients to promote the expansion of the garlic. If topdressing is carried out after harvesting garlic, it will easily lead to reduced production of greed. If the field is fatter and the garlic leaves are thicker, the fertilizer may not be applied. Due to the late twitching, the temperature of the middle and late-maturing varieties is high. After harvesting, the garlic is generally collected for about 20-25 days, so it is also possible to avoid the swelling of the fat.

2, garlic field water management

Qi seedling period: generally seeded for 1 week, Qi Miao. After chasing Qi Miaofei, if the soil is dry, it can be irrigated once to promote seedling growth.

In the middle and late stages of seedlings: it is marked by the end of wintering and the end of withdrawal. This stage is longer, and it is also an important period for the growth of garlic. If the soil is dry, it should be watered once; after winter, the temperature will gradually rise, and the seedlings will begin to grow vigorously. Water should be poured in time to promote the growth of garlic leaves and thickening of pseudo stems.

The twitching period: the leaves of garlic differentiation have all been exhibited, the leaf area has reached the peak, the root system has also expanded to the maximum extent, and the growth of garlic stalks is accelerated. This period is the period when the amount of fertilizer and water is the largest, and it should be timely watered after the recovery of cockroach Pumping water. After the “now tail”, water should be continuously watered to promote the seedlings with water, and the water should be stopped 2 to 3 days before the harvest to facilitate storage and transportation.

The period of expansion of the garlic: the garlic is immediately watered after harvesting to promote the rapid expansion and weight gain of the garlic. Before harvesting the garlic. Stop watering for 5 days, control the growth, and promote the assimilation of the leaf parts to accelerate the transfer to the garlic.

Finally, Xiaobian reminds everyone that the green food garlic base should be far away from the city, industrial and mining areas and major transportation routes, and there are no “three wastes” emission enterprises in the base area and surrounding areas. The farmland has a good atmospheric environment, and the irrigation water quality and soil environmental quality must conform to the Environmental Quality Standard for Green Food Producing Areas. The soil suitable for the growth of garlic should have a deep plough layer and fertile soil. The organic matter content is above 1.0%, and the loam is the best.
