1. Strictly choose the ground and apply enough base fertilizer. The soil layer is deep and fertile, and drainage and irrigation are convenient. There is no cotton field (the first two are not used for ginger) in the cotton field. Before winter, it is fully deep-turned and 1,000 kg of organic manure such as cow dung and crop straw are planted in the ginger planting pots for every one acre, in order to cultivate fertility.
2, a reasonable allocation, the standard to do. Appropriately widen the row spacing of the cotton, and carry out planting on the same line, with a width of 70 cm (including a ditch), 1 row of cotton and 1 row of ginger.
Second, cotton management requirements
Cotton varieties should use insect-resistant hybrid cotton varieties. Before the planting, the land was turned 25 centimeters deep and combined with arable land to apply basal fertiliser and mus applicator 5% phoxim granules 2-3 kilograms to control underground pests. The suitable sowing date for cotton is in early April, and the sunny days are covered with double-film nutrition seedlings. In the first half of May, 3,400 plants were transplanted per mu. Other management measures are the same as conventional cotton fields, but care must be taken to control and spray boron fertilizer, potassium dihydrogen phosphate, and other solutions with the help of mesitride.
Third, ginger cultivation techniques
1, select ginger seeds, fine processing. 1 Seed selection: In early March, ginger seedlings will be grown in the pit, and the ginger seeds that are hypertrophic, non-injury, disease-free, insect-free, and non-color-changing will be selected. 2 Shaizhong smoked species: The selected ginger seeds will be dried in the sun for 2-3 days, and then put on the top of the stove fire (commonly known as the smoker's eye) for about 20 days, which can be sterilized and prevented. 3 germination: smoke after the hot bed germination. First spread 20 cm thick cowshed manure and keep it practical, place 7-9 cm thick loam on it, then put into ginger seed, then cover 3 cm thick fine soil on ginger seed, cover it with agricultural film, and use soil around Compaction, heat preservation and germination. After the shoots grow to 4 cm, the buds will be split into 3-5 pieces. Each piece must have 1-2 buds and weigh 50-100 grams. At the same time, the buds with black base, red eyes, and more fibers after the chin were removed and then transplanted.
2, to ensure quality, standard transplanting. Transplanting ginger in late April is done by first opening a transplanting trench 25 cm wide and 9 cm deep, arranging ginger at a spacing of 20-50 cm, and planting a ginger density of 3500-4000 plants per acre. Cover the buds.
3, strengthen management, cotton and ginger take into account. Ginger management: First, topdressing. When the height of seedlings is 30 cm, 25 kg of carbonic amine and 15 kg of dried cake are mixed per acre, and 7-10 cm of furrows are planted 10 centimeters away from the ginger plant. It is forbidden to put urea, carbon amine, and unrefined human feces. Urine is applied directly to the plants. Before and after the beginning of the fall, 25 kilograms of dried fruit and 10 kilograms of urea were applied to each point of the ginger. The second is timely watering and drainage. After the ginger is drained, it is necessary to pour solid water in time in case of drought. In the mildew season, it is necessary to clear the drain. In case of drought, it is necessary to dilute the water, so that it can be filled with water for 7 days or so to keep the soil moist. The third is to prevent ginger rickets. Ginger disease focuses on prevention. It can be soaked with compound Bordeaux 1000 times for 20 minutes during transplanting, and sprayed with compound Bordeaux 500 times for 7-10 days in June-July. Once the diseased plant is found, it should be removed as soon as possible. Disinfect lime around diseased plants to prevent the spread of disease.
At the same time, we must do a good job in field management such as ripping, weeding, earth-cultivation, lateral buds, and picking ginger.
