Special integrated cultivation mode combining complete nutrient solution and organic substrate for summer squash

Abstract

The invention relates to a special integrated cultivation mode which combines a complete nutrient solution and an organic substrate for a summer squash. The special integrated cultivation mode comprises the steps that organic waste, such as crop straws, waste residues after edible fungi cultivation, excrement of animals and the like, is subjected to innocent treatment as a culture substrate for the summer squash instead of soil; and a water soluble fertilizer is used for producing the complete nutrient solution according to a nutrient element absorption ratio of the summer squash, and water and nutrient elements are supplied to the root system area of the summer squash in a manner of integration of water and fertilizer. The cultivation mode provided by the invention is adopted to plant the summer squash, and has the characteristics of safety in fertilizer application, water saving, labor saving, low cost, easiness in obtaining of raw materials of the substrate, high fertilizer and water utilization ratio, prevention of soil-borne diseases, and the like; compared with planting in common soil, the summer squash produced by the technical mode provided by the invention has the characteristics of low abortive fruit ratio, high yield, fine flesh, good taste, abundant nutrition, low pesticide residue, neat fruit twig, few malformed fruits, high commodity rate and the like; summer squash with high yield and high quality can be produced in places, such as severe saline-alkali soil, mountain ridge poor land, abandoned mining lands and the like where normal agricultural production cannot be performed.

Description

(1) Technical field [0001] The invention is a supporting technology suitable for cultivating zucchini in greenhouses or plastic greenhouses. (2) Background technology [0002] Zucchini is one of the solanaceous vegetable crops with a large winter cultivation area in greenhouses in northern China. Large-scale and specialized production of zucchini has caused many years of continuous cropping and other disadvantages, and has produced zucchini root-knot nematodes, fusarium wilt, root rot, Soil-borne diseases such as bacterial wilt have seriously affected the yield, quality and income of vegetable farmers of zucchini. In order to maintain high yields, vegetable farmers have to rely on extensive use of pesticides to control zucchini diseases. On the other hand, concentrated planting and long-term unreasonable fertilization ratios make the ratio of nutrients in the soil unbalanced, and the utilization rate of fertilizers continues to decline. Vegetable farmers must rely on large ...

AI Technical Summary

Problems solved by technology

On the other hand, concentrated planting and long-term unreasonable fertilization ratios make the ratio of nutrients in the soil unbalanced, and the utilization rate of fertilizers continues to decline. Vegetable farmers must rely on large amounts of fertilizers to maintain high yields of zucchini. This not only increases production costs year after year, but also causes Accumulation of soil salt and excess fertilizers have also caused serious environmental problems
