Transplanting-free floating plate and application of transplanting-free floating plate in leek floating cultivation

Abstract

The invention provides a transplanting-free floating plate and application of the transplanting-free floating plate in leek floating cultivation. The hydroponic floating plate comprises a floating plate body, a plurality of cultivation holes are distributed in the floating plate body in a rectangular array manner, each cultivation hole is designed to be large in top and small in bottom, namely, each cultivation hole is composed of an upper hole and a lower hole, and the diameter of each upper hole is larger than that of the corresponding lower hole. The upper holes can be cylindrical holes; and the lower holes can be inverted-circular-truncated-cone-shaped holes, the upper diameter of each inverted-circular-truncated-cone-shaped hole is larger than the lower diameter of the corresponding inverted-circular-truncated-cone-shaped hole, and the diameter of the cylindrical holes is larger than the upper diameter of the inverted-circular-truncated-cone-shaped holes. According to the novel floating plate designed and developed by the invention, direct seeding of leek floating cultivation is realized, transplanting is not needed, green moss can be effectively reduced, and growth of leek ispromoted.

Description

technical field [0001] The invention relates to a transplant-free floating plate and its application in leek floating cultivation, belonging to the field of leek hydroponic cultivation. Background technique [0002] Leek (Allium tuberosum R.) is widely cultivated in various parts of China, and is a special vegetable in my country, which is deeply loved by consumers. Soil cultivation, as a traditional cultivation method, suffers from pests such as leek maggots, and is difficult to control. A large amount of or highly toxic pesticides are often used in the production process, resulting in the problem of pesticide residues in leek products. Soilless cultivation, as a new and efficient way to solve problems such as soil continuous cropping obstacles, has gradually been applied in the production of leeks. The root system of nutrient solution culture leeks grows in the nutrient solution, which fundamentally eliminates the growth environment of leek maggots. It can well prevent le...

Problems solved by technology

[0004] Aiming at the existing leek floating production needs seedling transplanting, severe green moss and weak growth, the present invention provides a new type of hydroponic floating plate, by designing the hole in the form of a large top and a small bottom, and using a sowing sponge and Cover perlite to realize the free transplanting and less green moss of leek floating cultivation, combined with supporting nutrient solution and management technology, realize high-quality and efficient production of leek
