Root-protecting base fertilizer and preparation method thereof

Abstract

The invention relates to the technical field of planting and particularly relates to a root-protecting base fertilizer and a preparation method thereof. The root-protecting base fertilizer contains an organic fertilizer and a plant source pesticide in a weight ratio of (50-70) to (8-15), wherein the plant source pesticide includes an active component and an auxiliary component which is 1%-3% of weight of the active component. The active component is extracted from ground melon seeds, thermopsis lanceolata, Chinese wisteria leaves, radix phytolaccae, falsehellebore root and rhizome, chili and onions and matched with the active component so as to prepare the plant source pesticide with a porous structure. The plant source pesticide is added into the organic fertilizer to form the root-protecting base fertilizer, and the root-protecting base fertilizer is applied to the soil, so that the soil fertility is increased, meanwhile, the active component can be slowly released, multiple crop pests and pathogenic bacteria in the soil can be effectively inhibited and killed, the injury caused the pathogenic bacteria and the pests to roots of plants is effectively avoided, the nutrient absorption capacity of the roots is enhanced, the growth of plants is promoted, and the yield is increased.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of planting technology, in particular to a root mulching base fertilizer and a preparation method thereof [0003] 【Background technique】 [0004] Base fertilizer, also called base fertilizer, is generally applied before sowing or transplanting, or perennial fruit trees for the first time in each growing season. It mainly supplies the nutrients needed by plants throughout the growth period and creates good soil for crop growth and development. It also has the effect of improving soil and fertilizing soil fertility. Most of the fertilizers used as base fertilizers are late-acting fertilizers. Barnyard manure, compost, and livestock manure are the most commonly used base fertilizers. Phosphate and potassium fertilizers of chemical fertilizers are generally used as mulch base fertilizers. Nitrogen fertilizers of chemical fertilizers, such as ammonia water, liquid ammonia, and Ammonium bicarbonate, precipitated c...

Problems solved by technology

[0005] The main function of the existing base fertilizer is to provide nutrients to the plants. When the plants are planted, the roots are located in the soil. The soil environment is complex, and there are a large number of pests and bacteria, which will eat and infect the roots of the plants, which is not conducive to the growth of the roots. Absorption is blocked, resulting in poor plant growth
