Interplanting garlic in cotton field

Interplanting garlic in cotton fields can produce 93 kilograms of lint and 1300 kilograms of garlic per mu, with an benefit of about 3300 yuan per mu.

I. Cotton

Insect-resistant hybrid cotton varieties such as Kemian 3 and Kemian 6 were selected. Before sowing, the soil was ploughed 25 cm deep, and 3000 kg of rotten livestock and poultry manure and 60 kg of potassium sulfate compound fertilizer were applied per mu of ploughed land. Apply 5% phoxim granules 2-3 kg per mu to control underground pests. The suitable sowing time of cotton in Pizhou City is around April 3, the seedlings are raised in double-film nutrition bowls covered with sunny days, about 3000 bowls per mu of field are made, and dry seeds are sown after pouring enough bottom water on the seedbed, and about 0.35kg of cotton seeds are needed to be coated in each mu of field. After completing the seedlings, ventilate and reduce humidity in time, control diseases and insect pests, and cultivate strong seedlings. Around May and December, cotton seedlings were transplanted at 4-leaf stage and planted with equal row spacing. The row spacing was 1.2m, the plant spacing was 33cm, and about 1700 plants were planted per mu. In the middle and last ten days of May, 15-20 kg urea, 50 kg calcium superphosphate and 20 kg potassium chloride were applied per mu. Around July 20, 30 kg of urea and 15 kg of potassium chloride were applied per mu according to the growth of cotton. In the first ten days of August, long pick fertilizer was applied, and 7.5-10 kg of urea per mu. Pay attention to spraying boron fertilizer, potassium dihydrogen phosphate and other micro-fertilizer solution. Use zymophorin chemical control 4 times, use 1-1.5 grams per mu in full bud stage, 2-2.5 grams per mu in early flowering stage, 3-4 grams per mu in full flowering stage, and 3-5 grams per mu after topping. Hit the top around August 6th. Pay attention to the control of the third generation of cotton bollworm, cotton aphid, blind Toona sinensis, red spider, Bemisia Tabaci and other pests. Pull out the cotton stalk in the middle of November.

Second, garlic

Select the variety of Pizhou white garlic. In late September, cotton was sown in trenches between rows, with row spacing of 20 cm, hole spacing of 15 cm, seed consumption of 125kg per mu, and fixed seedlings of 2.5-28000 plants per mu. After sowing, cover 2-3 cm thick fine soil, spray garlic field herbicide, cover with plastic film. Pour frozen water before winter and melt it after overwintering. Water in time according to soil moisture from April to May. Combine with watering to apply good seedling fertilizer, and sprinkle it with 10 kg urea per mu. Bolting fertilizer is applied with 25-30kg compound fertilizer per mu. Pay attention to the control of garlic leaf blight, white rot and garlic maggots. Garlic bolts were harvested in the middle and late May, and garlic was harvested when most of the leaves dried up and the pseudostems became soft 18-20 days after bolting.
