Muskmelon seedling growing substrate

Abstract

The invention discloses a muskmelon seedling growing substrate, and belongs to the technical field of seedling growing substrates. The muskmelon seedling growing substrate is prepared from thoroughly-decomposed maize straw, thoroughly-decomposed chicken dung, turfy soil, vermiculite, antagonistic actinomycetes and chitosan, and the mass ratio of thoroughly-decomposed maize straw to thoroughly-decomposed chicken dung to turfy soil, vermiculite to antagonistic actinomycetes to chitosan is 1:(0.08-0.12):(0.8-1.2):(0.8-1.2):(0.04-0.06):(0.06-0.1). According to the muskmelon seedling growing substrate, the substrate contains antagonistic actinomycetes, the antagonistic actinomycetes has the good colonization capability in rhizosphere soil, the good inhibiting effect is achieved for greenhouse soil-borne diseases, and the continuous cropping obstacle can be effectively repaired; the PPO activity of muskmelon seedling stage leaves and roots is improved, and the muskmelon plant disease resistance is improved; the substrate is a compound substrate, the substrate is loose and good in water binding capacity, the total-P, total-K, quick-acting N, quick-acting P and quick-acting K contents arehigh, the fruit quality can be improved, and the fruit yield can be increased.

Description

technical field [0001] The invention belongs to the technical field of seedling-raising substrates, and in particular relates to a melon seedling-raising substrate. Background technique [0002] For a long time, my country has always been the largest country in the production and consumption of melons. The area of ​​melons accounts for more than 45% of the world's total area, and the output accounts for about 50%. Melon has become an important economic crop in my country, and the development of the melon industry has played an important role in increasing farmers' income. The quality of melon seedlings directly affects the yield of melons. As the saying goes: "Seventy percent of the harvest is strong." Under the same management conditions, the seedling substrate plays an extremely critical role in the quality of the seedlings. [0003] At present, in the process of raising traditional melon seedlings in China, most farmers use "big field soil" for configuration. The grain...

AI Technical Summary

Problems solved by technology

[0003] At present, in the process of raising traditional melon seedlings in China, most farmers use "big field soil" for configuration. Particles are not harvested; farmers who have the conditions buy peat soil for seedling cultivation. However, peat soil is a non-renewable resource. Excessive exploitation will cause environmental damage, and it has no preventive effect on soil-borne diseases, and the quality of seedling cultivation is also average.

For industrialized large-scale seedling cultivation, the special seedling substrate synthesized from various raw materials sold on the market is purchased. The effect is much better than that of "field soil" and peat soil, but it does not have any effect on the soil-borne diseases and continuous sitting obstacles that melon farmers talk about. Control effect

[0004] Moreover, after the seedlings are planted in the shed, the high-quality, cost-effective functional melon seedling substrate that can still overcome soil-borne diseases and sit-up obstacles has not been seen yet.

There is also the low seedling quality of the common seedling-raising substrate, which only plays the role of seedling raising, and cannot increase fruit quality and output.
