Laying the bed for multi-layer garlic planting has the advantages of low fuel consumption, good greenhouse heat storage performance, high space utilization rate at the production site, and significant economic benefits, which is of great significance for solving the winter vegetable supply problem. Here we talk about the cultivation method of this kind of garlic.
1, the garlic greenhouse selection method
The greenhouse used for the cultivation of multi-layer beds of garlic seedlings is basically the same as the general solar greenhouse. The south slope of the greenhouse is covered with a plastic film covering the grasshopper at night. Each 200m2 greenhouse can be equipped with 4 warming stoves. The flue is made of iron chimney or a fire wall.
2, erection bed method garlic planting
Bed position and materials. The front and rear of the greenhouse are relatively short, with a 2-tiered bed, and a 3-tiered upper shelf with a 80-centimeter spacing. The materials used for the bed are wooden poles, straw, plastic film, iron wire and red brick. During the erection of the bed, the wooden rods must be firmly tied to prevent watering from falling during the growth of garlic sprouts.
3, garlic planting management methods
(l) The choice of garlic. Choose white heads with large heads, many flaps, and short resting periods.
(2) Dipping garlic bulbs. Garlic in a larger container and then soaked in water at 20°C for 30 hours to allow the garlic to swell. Drain the drain after wet and dig the stem.
(3) Put garlic pressure sand. About 15 kilograms of garlic per square meter. The tighter the garlic is, the better. Garlic gap filled with loose garlic. Garlic covered with 3 cm thick fine sand, and then shoot. Every three days before shooting again, so as not to garlic "jump garlic."
(4) Water Management. The growth of garlic sprouts depends on their own nutrition. In addition to the temperature, the water that has the greatest impact is the water. Water temperature should not be less than 15°C, preferably about 20°C. General early stage of growth (after planting garlic) pouring water, the middle stage of growth (15-19 cm seedling height) pouring water, late growth (4 days before harvest) pouring water. The bed garlic sprouts are exposed in the space, the water loss is fast, and the number of watering depends on the dry and wet conditions of the bed soil to maintain the degree of moisture.
(5) Temperature management. Keeping the film surface clean can increase the light transmittance in the greenhouse and increase the source of heat. If the indoor temperature is lower than 16°C during the day and the temperature is lower than 12°C during the night, it is necessary to add heat and heat. Raised garlic temperature control range: After planting garlic, 26-28 °C/24-26 °C (day / night); Miao Qi, 27-24 °C / 20-22 °C; seedling height 15 cm, 20-22 °C /18—20°C; before harvest, l8-20°C/14-16°C.
4, timely harvest of garlic
When the garlic grows to 35 cm in height and the seedling leaves are slightly tilted, they should be harvested in time. The garlic seedlings were planted from garlic to harvest the first knife for about 20 days. After the first knife is harvested, the young seedlings will heal and grow and then water. About 20-22 days later, when the seedling grows to a height of about 30 centimeters, the second knife is harvested. Each kilogram of garlic can be 1.1-14 kilograms of garlic.
