Crop rotation cultivation method of eggplants harvested in winter and spring and rice

Abstract

The invention discloses a crop rotation cultivation method of eggplants harvested in winter and spring and rice. The method comprises the steps of selection of rootstocks and scions, matrix preparation, sowing and seedling raising, processing of eggplant planting field blocks and field planting, plant management, harvest in winter, broken branch regeneration, regenerated plant management, harvest in spring, rice planting and the like. According to the method, sowing and seedling raising are conducted in early of middle of July, and field planting is conducted during mid-to-late September and early October, not only is the seedling age short, but also the influence on eggplant growth by low temperature in winter can be effectively avoided. Furthermore, by adopting the method, double-season harvest in winter and spring is achieved, the total yield of two seasons can reach 9000-11500 jin/mu, the total benefits reach 9000-12500 yuan/mu, and the yield and the benefits increase by 22-28%.

Description

technical field [0001] The invention relates to a crop rotation method, in particular to a cultivation method for crop rotation of eggplant and rice harvested in winter and spring. Background technique [0002] Eggplant early spring cultivation technology is under the "rice vegetable" rotation mode, select early-maturing low-temperature and low-light varieties, use eggplant greenhouse cold-bed seedling cultivation technology, use seedling beds to sow seedlings from the end of September to early October, and fake planting to 10cm × in early and mid-November The 10cm nutrition cup adopts mulch + small arch shed + greenhouse to survive the winter, the beginning of spring - rainwater older seedlings are planted, and the eggplant bud stage uses growth regulators to preserve flowers and fruits, and the eggplant will be on the market in mid-April. Using this method not only has a long seedling age and high management costs, but the seedling period from seedling cultivation to plant...
