Abstract
The invention belongs to the technical field of agriculture, and particularly provides a whole-course health management method for rice production and application thereof, wherein the whole-course health management method for rice production at least comprises any one or more of the following steps: a. seed dressing before sowing; b. the seedbed is put into the field with medicines; c. sealing and weeding before transplanting rice seedlings; d. sealing and weeding after transplanting and turning green; e. weeding stems and leaves in the growing period of rice; f. insect prevention, disease prevention, quality improvement and yield increase in the growing period. The invention adjusts the growth and yield increase of rice from the omnibearing angles of insect pest, disease, grass pest, crop nutrition, adjustment and the like. A complete solution is provided from seed coating to the last booting stage.
Description
Technical Field
The invention relates to the technical field of agriculture, in particular to a whole-course health management method for rice production and application thereof.
Background
With the development of economy and the improvement of living standard, the demand of people for rice is no longer satisfied in quantity, but a higher demand for quality is put forth. At present, common diseases of seedbeds: damping off, soft rot, bacterial wilt, bakanae disease, etc. Major weeds: barnyard grass, moldavica dragonhead, glossoides gloriosa, arrowhead (donkey ear), longhead (orchid), oriental waterplantain rhizome (Chinese cabbage), acalypha australis, polygonum caryophyllum, eclipta alba, cyperus rotundus, scirpus aculeatus, scirpus planiculus and the like. "three vegetables in paddy field", rice Lei's grass, wild rice (Jiang Bai), reed, fluorescent rush (herba Alii Fistulosi), scirpus planiculus, etc. Major diseases in the growing period: rice blast, banded sclerotial blight, false smut, bacterial brown spot and the like.
