Continuous cropping resistant composite soil improvement agent special for facility agriculture

Abstract

The invention relates to the fields of agricultural planting and soil improvement agents and in particular relates to a continuous cropping resistant composite soil improvement agent special for facility agriculture. Agricultural wastes, namely wheat straws, are taken as a principle component and a carrier of the continuous cropping resistant composite soil improvement agent, multiple natural phytoncides and insecticides are screened, the formula composition is subjected to proportional optimization, and finally the continuous cropping resistant composite soil improvement agent composed of thewheat straws, garlic extract, radix stemonae extract, heartleaf houttuynia herb extract, nano chitosan and composite trace elements is obtained. The soil improvement agent disclosed by the inventionis low in cost, convenient to operate, safe to use, stable and long-acting, provides a novel pathway for recycling of the wheat straws and contributes to saving natural resources, easing the energy crisis and protecting the ecological environment.

Description

technical field [0001] The invention relates to the field of agricultural planting and soil improver, in particular to a compound soil improver for anti-heavy cropping specially used for facility agriculture. Background technique [0002] As the largest agricultural producer in the world, my country ranks first in the world in the possession of crop straw resources. In 2016, the straw output reached about 840 million tons, accounting for 17.29% of the world's annual straw output. Therefore, China has also become the world's largest straw producer. Among all kinds of straw, the annual output of wheat straw is close to 150 million tons, but the comprehensive utilization rate of wheat straw is still less than 30%. There are many problems such as weak support, shortage of supporting equipment, difficulties in implementing support policies, and unsound collection and storage systems. The traditional incineration treatment method will not only cause serious pollution to the enviro...

Problems solved by technology

Among all kinds of straw, the annual output of wheat straw is close to 150 million tons, but the comprehensive utilization rate of wheat straw is still less than 30%. There are many problems such as weak support, shortage of supporting equipment, difficulties in implementing support policies, and unsound collection and storage systems. The traditional incineration treatment method will not only cause serious pollution to the environment, but also a huge waste of organic resources.

[0005] At present, most of the anti-stubble soil amendments used in protected agricultural production are beneficial microbial preparations, but because of their disadvantages such as high price, complicated production process, unstable living products, short retention time, and difficult operation, their large-scale application is greatly limited. promotional use of

[0006] Through long-term vegetable planting and cultivation experiments, we have developed a very simple compound anti-stubble compound soil improver. It does not add additional chemical antibiotics and preservatives to its formula. It is safe to use and will not affect the growth and development of plants and crops. The quality of the product produces any adverse effects, and the anti-repeated cropping composite soil improver of the present invention has the advantages of low cost, easy to use (just apply it to the soil), stable and long-lasting, and the anti-repeated cropping compound soil similar to the present invention Improvers have not been applied in current facility agricultural production
