Earth warm pit production garlic yellow 5 points

First, choose the best species

Choosing Cangshan White Garlic has good quality and high yield. It is an ideal variety for planting garlic yellow.

Second, build a warm cellar

Digging warm cellar, the general height of 2 ~ 2.5 meters, into the soil depth of 1 meter, exposing the ground height of 1 meter, cell length 7 meters, width 7 meters (cultivation area control in about 50 square meters), with a wooden frame or The bamboo poles are well-supported (it must be firmly fixed and the soil is to be covered), and then corn, straw, wheat straw, or ragweed etc. are covered, and the top is covered with clay, and the thickness is about 40 cm. Leave a ventilation window. Dig the entrance, the width of 40 to 50 cm, both sides with a good barrier. The cultivated bed soil is preferably made of organic-rich loam. The thickness of the soil layer is 10 to 12 cm. The surface of the cultivation pond should be flat, and the sand or sandy loam soil should be about 6 cm.

Third, placed garlic species

Treatment is done prior to sowing by stripping the bulb's skin, the base stem plate, and some or all of the garlic peel. Before sowing, low temperature treatment of 0~4°C should be carried out. After low temperature treatment, the kind of garlic can emerge in advance. In addition, soaking in fresh water before sowing, so that the kind of garlic fully absorb water and accelerate germination. In order to increase the yield per unit area, the method of close planting should be used as far as possible when planting. When planting, the garlic should be planted closely in a planting pot, one by one. Immediately after sowing, the clay was covered with 3 to 4 cm thick, covered with a gauze on the bed of the accompany culture. The gauze was about 30 cm from the surface and supported with bamboo poles and wooden sticks. Covering gauze is mainly used to support garlic yellow, which can play a role in preventing lodging. After pouring a permeable water, cover the shade.

Fourth, Putian management

The key to management is timely and adequate watering, control of soil moisture and promotion of rapid leaf growth. Minimize watering. Usually, it is poured once after planting, maintains high humidity, and guarantees that garlic grows quickly. Later, according to the outside temperature, soil moisture, garlic yellow growth conditions, flexible watering, can not make the humidity in the warming cellar too high. In the early stage of growth, the amount of water spray should be small and gradually increase in the middle and later stages. Spraying potassium dihydrogen phosphate foliar fertilizer can increase the yield and improve the lodging resistance. Before the harvest, a small amount of water is poured once again to ensure that the yield and quality of garlic yellow, but also to lay the foundation for continued growth after harvest. After the beginning of the winter, the outside temperature is significantly reduced. To raise the temperature in the cultivating pits to keep the temperature normal, when the daytime temperature exceeds 20°C, it is necessary to cool the air and prevent the high temperatures from being long.

Fifth, timely harvest

Garlic can be harvested when it reaches a height of 35 to 45 cm. In general, garlic yellow takes 25 days from planting to cutting knife, and the second knife can be collected in about 20 days. Harvest it when it is harvested. Do not root it up. The garlic garlic harvested is tied into bundles and basks in the sun, turning the garlic leaves from white to golden. In the production process, the sowing date should be determined flexibly according to the harvest period so as to maximize the economic benefits.
