Special full-value nutrient solution and organic substrate integrated cultivation mode for cucumber

Abstract

The invention relates to a special full-value nutrient solution and organic substrate integrated cultivation mode for a cucumber, which comprises the steps that organic waste such as crop straws, waste residues after edible fungi cultivation and animal excrement serves as a raw material, and serves as a cucumber cultivation substrate to replace soil through innocent treatment; a full-value nutrient solution is prepared by a water soluble fertilizer according to a fertilizer requirement rule of the cucumber; and moisture and nutrient elements are supplied to a root area of the cucumber in a water and fertilizer integration manner. The cultivation mode for the cucumber has the characteristics that the cultivation mode is safe in cultivation, water-saving, labor-saving, low in cost, and high in fertilizer utilization rate, avoids soil-borne diseases, and the raw substrate is easy to get; compared with common soil cultivation, the cucumber produced in the technical mode has the characteristics that the cucumber is high in yield, rich in nutrition, low in pesticide residue, straight in shape, light green in color, less in deformation and high in commodity rate, and people have no unsmooth feel when eating the uncooked cucumber; and the high-yield and high-quality cucumber can be produced in places where normal agricultural production cannot be conducted, such as heavy saline-alkali land, poor ridge land and abandoned industrial and mining land.

Description

(1) Technical field [0001] The invention is a supporting technology suitable for cultivating cucumbers in winter-warm solar greenhouses or plastic greenhouses. (2) Background technology [0002] China is the country with the largest cultivation area and the highest total output of cucumber in the world, with an annual planting area of ​​about 1 million hectares 2 About (China Agricultural Statistics). Cucumber is a solanaceous vegetable with a large winter cultivation area in solar greenhouses in northern China. Specialized cucumber production, especially greenhouse cucumber production, has become one of the main profitable agriculture in many areas. Due to the needs of large-scale and specialized production, there are generally disadvantages such as high multiple cropping index and continuous cropping for many years, and therefore it is very easy to produce soil-borne diseases such as root-knot nematodes, fusarium wilt, root rot, and bacterial wilt. In order to maintain ...

AI Technical Summary

Problems solved by technology

In addition, concentrated planting for successive years and long-term unreasonable fertilization ratios lead to an imbalance of soil nutrient ratios, and the utilization rate of fertilizers continues to decline. Vegetable farmers must rely on large amounts of fertilizers to maintain high yields of cucumbers, which not only increases production costs, but also causes accumulation of soil salinity. Become secondary saline soil, endangering the sustainable production of cucumber
