What are the key points of moisture management for garlic?

1. Fertilizer management

(1) Apply sufficient base fertilizer

“If the base fertilizer is not applied well, garlic will be like a grass.” Base fertilizer has a far-reaching effect on increasing garlic production. Higher than top dressing. Usually, the following two methods can be used to apply sufficient base fertilizer: ① Repeated cropping land: apply 80-120 kg of Jinzheng 5 15 high-concentration humic acid complex functional fertilizer per mu; ② New cropping land: apply 2-3 cubic meters of decomposed chicken manure or other per mu 6-8 cubic meters of farmyard manure, 80-100 kilograms of 3 15 compound fertilizers, 20 kilograms of Garlic Dikang or Jindi Kang.

(2) Seedling-stimulating fertilizer

Seedling-stimulating fertilizer is usually carried out about 15 days after emergence. Generally, 15 kg of Ladomei 24-10-16 long-acting chelated fertilizer can be used per mu. +4kg Gaimei 101 is spread or poured. Watering or irrigation is required in time after spreading. However, if the fertility is higher and the base fertilizer is sufficient, it is not necessary to apply seedling fertilizer.

(3) Greening fertilizer

Generally, it is applied in spring when the temperature rises and the heart leaves and roots of garlic begin to grow. The appropriate dosage is 10-15 kg of standard nitrogen fertilizer.

(4) Head-strengthening fertilizer

The fertilization time is a few days before and after the garlic planting. The purpose of applying strong-head fertilizer is to promote the expansion of the garlic and increase the yield of the garlic. This top dressing is Mainly nitrogen fertilizer, combined with a small amount of phosphorus and potassium fertilizer, the dosage is 20-30% of the total top dressing.

Water management

Garlic requires a lot of water, and generally needs to be watered 4 times during the entire growth period.

(1) Covering water: Garlic needs to be watered promptly after sowing, watering enough to ensure that no one plant leaks, and 100 cubic meters of water per 667 square meters. This water not only meets the needs of garlic planting, but also provides convenience for covering with mulch.

(2) Water to strengthen seedlings: Watering is generally done around early April or when the ground temperature is above 15°C.

(3) Water for moss emergence: Pour this water as soon as the garlic moss emerges.

(4) Swelling water: Pour this water after pulling out the garlic moss.

Although garlic leaves are highly drought-tolerant, their root systems have shallow penetration and weak absorptive capacity. Therefore, garlic requires higher soil moisture, and different growth periods have different effects on soil moisture. Require. Especially in the seedling stage and early growth stage of garlic, watering is very particular. This is also the key to promoting good growth of garlic. The field is relatively dry, so it should be watered once to promote the growth of seedlings. Do not water until it is dry to prevent flooding and pay attention to The fields should be drained promptly after autumn rains. In addition, in * soil seal
