Autumn sowing garlic film cultivation techniques

1, fine selection, timely planting. The best choice for virus-free varieties such as: VF selection 1, VF05, VF06 and so on. According to the size and grade of garlic, cultivation was carried out: 500 g/100 flaps were first grade, 400 g/100 flaps were second grade, and 300 g/100 flaps were third grade. The soil with large alkaline soil can not be peeled when garlic is planted, so as to prevent alkali corrosion of the species flap. The appropriate sowing date for autumn sowing of garlic is 5 cm and the temperature is 18 to 20°C. It is appropriate to sow in early October.

2, Shizu base fertilizer, intensive cultivation. Autumn sowing garlic After the harvest of the crop, the fertilizer is applied together with the organic fertilizer on the surface, deep-turned over 25 centimeters, so that the fertilizer is evenly distributed in the soil, and then planted at an interval of 5 to 7 days. The dosage of organic fertilizer is 3,000-5,000 kilograms per mu, and it must be thoroughly cooked to prevent garlic sprouts from occurring. Chemical fertilizers can be selected from 18 to 20, 16-12-20, 16-16-16, etc. sulfur-based compound fertilizers, 70-80 kg per mu. The soil lacking trace elements, combined with the application of organic fertilizer, applied 2 kg of zinc sulfate per acre, 1 kg of borax, and 5 kg of ferrous sulfate per acre for alkaline soil. In the salt-free, good permeability soil can also be used 19-19-19, 18-18-18 and other types of chlorine-containing fertilizer.

3, correct planting, timely rupture membrane. Groove sowing method: The width is 2 to 3 meters wide, 8 to 12 rows each sowing, 15 to 20 cm spacing by row, ditch, the species flap 15-18 centimeters by planting into the soil, keep upright, seeding should be made The dorsal-ventral connection of the petal is parallel to the furrow so that the leaves and rows of the garlic sprouts are perpendicular to each other. About 35,000 acres are planted and 160-180 kg are used. After planting cover soil 1.5 to 2 cm, irrigated with water. At intervals of 2 to 3 days, spray the herbicide Gore (Estrofluthorax) or Shi Tianbu, the amount and concentration should be strictly in accordance with the instructions for use of pesticides, and then cover the membrane. Planted after 5 to 7 days of emergence, most garlic sprouts can be topped off the film surface exposed, a small number of garlic seedlings need to artificially assist seedling. This period should be checked once a day and it is found that garlic sprouts are not exposed on the membrane surface and are gently patted with a broom.

4, reasonable watering, appropriate fertilizer. Watering should be controlled before emergence until winter. If the soil moisture is too high, garlic will rotten the mother early and affect root development. Before and after the vernal equinox the following year is rotten mother, combined with pouring back to Qingshui, chase Shi Mei Sheng Fei 18-12-20 or 20-12-16, 20-25 kg per acre, can avoid or reduce the yellow tip phenomenon. After the growth of garlic into the long-term, pouring water once every half months, before picking 3 to 4 days to stop watering. Before convulsions should be combined with water per acre chase after 20 to 25 kilograms of Shijia Jiaji Fertilizer, timely watering after convulsions, keep the soil see dry see wet, to 5 to 7 days before harvest to stop watering. After spring, each top dressing can be flushed.

5, clove garlic mature, timely harvest. Garlic pods can be harvested in mid-to-late May. The signs of ripening are that the scapes become larger, the color becomes whiter, and the tops of the pods are bent into big hooks. After 18 to 20 days after the pod lifting, the leaves of the plants have mostly dried up and the pseudostems become soft. The garlic can be harvested at this time, the harvest is too late and it is easy to split the petals.
