Technique for preventing and controlling dead seedlings and rotten plants of crops through combined formula of chemicals and two bacteria

Abstract

The invention discloses a technique for preventing and controlling dead seedlings and rotten plants of crops through a combined formula of chemicals and two bacteria. The technique method comprises the following steps: performing basal application of bacillus subtilis at a ratio of 100-200 kg / mu to to-be-conditioned soil, and performing initial conditioning on the soil. The technique has the advantages that continuous cropping can be prevented effectively, dead plants can be treated, the crop growth is promoted, and the crop immunity is improved; meanwhile, when the crops suffer from cold damage, drought damage, flood damage, hail damage, pesticide damage, wind damage and other natural disasters, new roots of the crops can grow rapidly through combination of compound ammonium nitrate and Paenibacillus polymyxa, and the crops can be quickly recovered, so that loss is reduced, the yield is ensured, and the yield and income of farmers are improved; and the technique is suitable for multiple crops in all seasons within a year, the application amount of fertilizer can be reduced by 20-30%, crop planting, soil improvement and green agriculture development are facilitated, and economy andenvironmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of preventing and treating dead seedlings and rotten trees of crops, in particular to a technology for preventing dead seedlings and rotten trees of crops with a combined formula of a medicine and two kinds of bacteria. Background technique [0002] In recent years, the area of ​​cultivated land in our country has been decreasing. In order to improve the utilization rate of cultivated land, continuous farming has become the main cropping system at present. With the increase of the multiple cropping index of arable land, the phenomenon of dead plants and rotten seedlings of crops is increasing, reducing crop yield, and in severe cases, it will lead to crop failure and greatly reduce the economic value of crops. In addition, due to the extensive use of chemical fertilizers, not only increased Planting costs, and it is also not conducive to planting, raising land, and developing green agriculture.
