Description

Organic fertilizer with insecticidal effect

The technical field is as follows:

the invention belongs to the technical field of potato breeding, and particularly relates to an organic fertilizer with an insecticidal effect for producing potato breeder seeds.

Background art:

the potato stock is the preferable potato seed for modern potato planting, and is obtained by screening high-quality potato seeds, detoxifying the potato seeds, performing virus detection, starting tissue culture and rapid propagation to obtain tissue culture seedlings, performing water culture on the tissue culture seedlings to form strong seedlings, and cutting 10-15cm long high-strong potato seedlings for field planting after 10-15 days. At present, the original stock is obtained by cutting the detoxified seedling on a special substrate in a greenhouse for culture. Because the soil is directly used for planting the detoxified seedlings, the detoxified seedlings are generally difficult to survive or have extremely low survival rate, so that the original stock seeds are generally planted and produced by planting the detoxified seedlings by using a composite matrix consisting of vermiculite, organic fertilizer, soil and the like in an insect-proof net room at present.

The pest control in the breeding process of the original breeder seeds mainly controls aphids and early and late blight. Potato diseases represented by potato late blight and potato early blight seriously affect the yield and quality of potatoes, and become key and difficult points of prevention and control of the potato diseases and pests. Regularly and irregularly spraying, preventing, controlling and preventing imidacloprid, acetamiprid, pirimicarb, abamectin and other medicaments inside and outside a net room and in the surrounding environment, and timely treating the imidacloprid in the aphid migration hazard period; the metalaxyl manganese zinc, the jarosite, the Yinfari, the fast inhibitor, the Kelu and other medicaments are alternately sprayed to prevent, control and prevent the early and late blight. Although the traditional pesticide has a certain effect on preventing and treating plant diseases and insect pests, improper dosage or improper type of the traditional pesticide easily causes phytotoxicity, crops become more sensitive and are easy to generate drug resistance, and meanwhile, the potential threat of pesticide residues to the environment and human beings cannot be ignored.

The organic fertilizer is a fertilizer containing organic substances, which can provide various inorganic nutrients and organic nutrients for crops and can also fertilize and improve soil. Most of them are made of local materials by farmers and accumulated by oneself. Urban pollutants can also be changed into organic fertilizers through treatment. The organic fertilizer replaces inorganic fertilizer or is mixed with the inorganic fertilizer for application, so that the environmental problem can be effectively improved, and the environment and production waste can be effectively utilized to change waste into valuable. Various special crops such as sophora alopecuroide, purslane, selenium-containing fructus trichosanthis, medlar, narrow-leaved oleaster and the like are grown or planted in various areas of Ningxia, wastes generated in the processing process can increase the processing cost and cause environmental burden, and the inherent value of the crops needs to be reasonably processed and developed.
