Sparse planting and pruning method for producing eggplants in winter

Abstract

The invention belongs to cultivation of vegetable crops, and specifically relates to a sparse planting and pruning method for producing eggplants in winter. The method comprises the following steps: sparse planting, four-trunk pruning, cultivation with a lifting rope and the like. The method solves the disadvantages of high planting cost, poor fruit coloration, high disease incidence, low fruit-setting rate and the like in the prior art. The method can obviously improve ventilation and light transmission conditions in fields, and is beneficial to enhancing quality and economic benefits and reducing expenditure of the eggplants; and the obtained eggplants have the advantages of outstanding continuous fruition capability, high yield, uniform fruit coloration, good commodity property, low disease incidence, economy in labor and time, lower planting cost and the like.

Description

Technical field [0001] The invention belongs to the cultivation of vegetable crops, in particular to a method for sparsely planting and pruning eggplants in winter. Background technique [0002] Eggplant is one of the important nightshade vegetables. With the continuous advancement of science and technology, the production of eggplant in protected areas has made great progress. Compared with other forms of protected areas, the overwintering stubble of eggplant solar greenhouse is the most technically difficult, and a large number of eggplants are on the market in winter, which can achieve higher economic benefits. However, due to the different climate every year, low temperature and low sunlight have become a major bottleneck restricting the stable and high yield of eggplant solar greenhouses over winter. At present, in addition to selecting suitable varieties and adopting grafting technology for overwintering eggplant production in solar greenhouses, the general planting ...

AI Technical Summary

Problems solved by technology

Under the conditions of low temperature and little light in the solar greenhouse in winter, the disadvantages of using conventional density, double-pole or single-pole pruning are: first, the planting density is high, the labor intensity of seedling raising and grafting is too high, labor-intensive and time-consuming, and the cost is high. This is especially true for pruning; the second is that the density is high, the ventilation and light transmission are poor, the fruit coloring is not good, and the incidence of diseases is high; the third is that the potential of improving the quality and efficiency of the eggplant cannot be fully utilized, the fruit setting rate is low, the yield is low, and the appearance is poor.
