Method for producing rice capable of realizing disease and pest prevention, weed control and fertilizer reduction based on ducks and frogs

Abstract

The invention belongs to the technical field of rice weed prevention and control, and discloses a method for producing rice capable of realizing disease and pest prevention, weed control and fertilizer reduction based on ducks and frogs. The method comprises the following steps of planting green manure astragalus smicus in autumn and winter, performing plowing when the astragalus smicus is close to the maximum flowering biomass, performing anhydrous dry plowing, performing drying in the sun for 7-10 days, performing retting for 3-5 days, performing land preparation and rice transplanting by amachine, and performing irrigation with a depth of 7-10cm; after rice seedlings are transplanted for 15 days, putting 15 rice ducks, namely 15 Dongting little sheldrakes, which are 15 days old, per mu; then, according to the weed occurrence condition in the field, putting a proper amount of duck feed into an area with a high weed occurrence density, so as to solve the problem of hybrid damage. Themethod can efficiently solve the whole-process weed damage, the monocotyledonous weed generation amount can be reduced by 99.7% and the dicotyledonous weed generation amount can be reduced by 52.8% in the early stage, and compared with ''one-sealing two-killing three-supplementing'' conventional chemical weeding of middle-season rice in the later stage, the method can reduce the monocotyledonousweeds by 65.6%, and reduce the dicotyledonous weeds by 100%, and reduce the monocotyledonous weeds and the dicotyledonous weed by 92.1% in total.

Description

technical field [0001] The invention belongs to the technical field of rice weed prevention and control, and in particular relates to a method for producing rice by using duck frogs to prevent diseases, insects, insects, control weeds and lose weight. Background technique [0002] At present, rice production refers to a production system that does not use chemically synthesized fertilizers, pesticides, growth regulators and other substances during the entire growth period of rice, nor does it use genetically engineered organisms and their products. Its core is to establish and restore a virtuous circle of agricultural ecosystems to maintain the sustainable development of agriculture. Rice production is to improve soil fertility through the use of organic fertilizers and appropriate farming and breeding measures, and to control diseases, insects, and weeds through natural methods, such as reasonable crop rotation, agricultural control, biological pest control, and protection ...

AI Technical Summary

Problems solved by technology

In the case where herbicides cannot be used, in many cases only the method of manual weeding can be used

However, manual weeding has low efficiency, high labor intensity and difficult working conditions

[0003] In summary, the problems in the prior art are: low efficiency of manual weeding, high labor intensity, and difficult working conditions

Now farmers have accounted for 1 / 3-1 / 2 of the field labor in weeding, especially now that rice dry-seeding is widely promoted, weeds are reborn everywhere, and weeds also affect the efficiency of cultivated land and prolong working hours
