Diversified and multi-dimension three-dimensional planting is a high-yield and high-efficiency agricultural production form and supporting comprehensive technical system that conforms to the biological group structure. The development of diversified and multi-dimensional three-dimensional planting can achieve good economic, social and ecological benefits.
I. The mechanism of developing multi-dimensional and multi-dimensional planting of cotton in Huaibei area
1, according to local conditions, pay attention to efficiency. The three-dimensional cultivation of cotton involves a variety of crops, a variety of factors, and a variety of disciplines, and it has a strong temporal, regional, comprehensive, and scientific nature. Therefore, in order to combine the conditions of land and climate in Huaibei area, we must select appropriate time and species for cultivation.
2. Optimize the configuration and improve the utilization of light energy. The multi-dimensional multi-crop planting of cotton can be used to compose a compound group with the arrangement of crops such as tall stalks and dwarfs, grasses and legumes, narrow and broad leaves, shade and shade, so as to increase the photosynthetic area per unit area and increase the photosynthetic rate. effectiveness.
3. Use the growing season to improve land utilization. Through the intercropping of multi-medium cotton crops, the total number of days of crop growth is reduced, so that the growth period of different crops during the symbiotic period will advance. Overlapping overlaps can avoid the time spent on planting from planting to harvesting, matching different crops and varieties, and avoiding weaknesses, so as to give full play to their respective advantages and achieve mutual benefit and complementarity.
Second, the mouth arrangement. After the crop was let in, from late September to mid-October, the land was ploughed, the base fertilizer was applied, and the whole bread crumb was 310 cm wide. In late October, 70 cm of wheat was planted in the middle and 4 rows of green vegetables were planted on both sides. The plant spacing was 25 centimeters and 20 centimeters, and 12,900 plants were planted per hectare. The potato was incubated with moisturizing and preserving germination in late January. In mid-February, the cabbage was harvested and fertilized. The soil was ridged on both sides (80 centimeters in ridge width and 60 centimeters in ridge width). The plant spacing was 90 centimeters and 20 centimeters. Hectares were planted with 64,500 strains; harvesting was conducted between mid-May and late May. In early April, the cotton was nursed by seedlings. After the potatoes were harvested in late May, they were transplanted in rows of 100 cm in width, 55 cm in narrow rows and 30-35 cm in plant spacing.
Third, the main cultivation techniques
1. Vegetables: Overwintering vegetables are selected from high-quality, low-drinking and low-cold varieties. 2250 grams per hectare of field crops were planted in late September and transplanted in late October. During the growth period, pay attention to fertilizer and water management, adhere to light irrigation, ground pouring, and apply diluted fertilized water to raise the seedlings after waking the tree; apply antifreeze water before and after the onset of the cold current; apply heavy fertilizer once more; use 22,500 kg of decomposed manure per hectare to pour the water. Shi, collected before and after the Spring Festival.
2. Potatoes: Potatoes use precocious detoxification varieties. One month before sowing, the disease-free seed potato with smooth epidermis, colorful appearance, buds and eyes were selected, and the potato chips were cut into about 25 grams to induce germination. Before sowing, 37,500 kg of organic fertilizer was applied per hectare and 25% of compound fertilizer was 750 kg. After sowing, the pesticide was sprayed (1000 times 50% acetochlor solution) and covered with plastic film. After emergence, break the film in time and top up a small amount of diluted manure. The seedling height is more than 10 cm and then manure is applied once more, combined with soil, and promote seedlings and strong trees. Tubers are infested during the expansion period and should be watered and moisturized. Sheng Lei at the beginning of flowering stage, spraying 1-2 times of 50 mg/kg paclobutrazol for seedlings, reasonably adjusting the plants, accelerating the photosynthetic products to run underground, and picking up the market in mid-and-late May.
3, cotton: in early April for nutritional seedlings nursery, in mid-May transplanting planting. During transplanting, the deep ponds are planted according to the predetermined spacing of the plants. After the plants are planted, sufficient water is poured and the soil is compacted to improve the quality of transplanting, shorten the period of seedling sowing, rationally apply fertilizer, apply sufficient basic fertilizer and lightly apply Miaofei. More Shi Lei fertilizer, re-apply Hua bell fertilizer, Pu Shi cover top fertilizer.
