Abstract

The invention relates to nutrient soil with broad-spectrum insecticidal property and good water retention capacity. The nutrient soil is characterized by being prepared by the following steps: firstly extracting and separating sophocarpidine by virtue of an ultrasonic extraction-microwave extraction combined technique and trichloromethane extraction; and then carrying out microwave heating on attapulgite, vermiculite and zeolite so as to increase effective apertures of the attapulgite, the vermiculite and the zeolite, and introducing the sophocarpidine into the apertures of the attapulgite, the vermiculite and the zeolite; and finally carrying out cross-linking polymerization on acrylamide, as a monomer, and the attapulgite, the vermiculite and the zeolite under the catalysis of potassium persulfate, so as to obtain spatial reticular inorganic mineral-polymer particles, namely the nutrient soil with the broad-spectrum insecticidal property and the good water retention capacity. The nutrient soil disclosed by the invention has the broad-spectrum insecticidal property, is capable of improving a soil structure, improving soil organic matters and adjusting a soil microenvironment and is applicable to plantation of flowers and nursery stocks.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a nutrient soil with broad-spectrum insecticidal properties and good water retention performance and a preparation method thereof. Background technique [0002] Among agricultural pollution sources, pesticide pollution is the most serious aspect. Extensive use of highly toxic and high-residue broad-spectrum chemical pesticides not only causes serious pesticide content in farmland and agricultural products to exceed the standard, but also often causes human and animal poisoning incidents, threatening people's lives and health. In order to fundamentally change this situation, it is necessary to use high-efficiency, low-toxic or non-toxic, low-residue or no-residue botanical pesticides. Many types of plants contain components that kill diseases and insect pests, and after industrial extraction, they can be used as pesticides, that is, botanical pesticides. The vast majority ...
