Embodiment 1

[0041] A green rice planting and fish polyculture method, comprising the following process steps:

[0042] (1) Rice field construction:

[0043] a) Rotate the exposed rice field with a rotary tiller first, and level the farmland with a laser leveler;

[0044] b) Build a 0.8m-high cofferdam around the paddy field (widening and strengthening), as if the rice is planted in a basin, excavate a ring-shaped fish breeding ditch along the inner side of the paddy field stalk, the ditch is 1.0m wide and deep 1.5m (a step is designed every 30 meters of ditch length to prevent farmers from drowning);

[0045] c) Dig ditches and build culverts in the middle of the paddy fields, dig a "well" or "day"-shaped field ditch, the width of the field ditch is 0.7m, the depth is 0.6m, the length, width and depth of the culvert are 7×7×1.6m, and the circular fish breeding ditch The area of ​​Hetian fish breeding ditch accounts for about 10% of the total area of ​​rice fields;

[0046] d) The paddy f...

Abstract

The invention discloses a green rice planting and fish mixed culture method, and relates to the technical field of rice breeding. The method comprises the procedures of paddy field construction, greenrice planting, fish culture in the paddy field, and rice and fish harvesting. The mixed culture method adopted by the invention not only can prevent disease and insect pests, but also can achieve theeffect that each mu of paddy field produces 200-300 jin of fish and 850-1200 jin of rice; in the paddy field for fish culture, the rice yield is 5-10%; because fish is cultured in the paddy field, bio-organic fertilizer and biological biogas slurry fertilizer are used, herbicide is not used, quick-acting chemical fertilizer and the like are not used, pesticide pollution is effectively controlled,water quality is purified, ecological balance is promoted, and a good agricultural environment is guaranteed.

Description

technical field [0001] The invention relates to the field of handicraft surface treatment, in particular to a green rice planting and fish polyculture method. Background technique [0002] Rice is a kind of herbaceous Oryza genus, and it is also the most important and oldest one as food in Oryza genus. Originally produced in China, rice was planted in the Yangtze River Basin of China seven thousand years ago. The existing rice planting is generally planted under the condition of a certain water depth, the method is relatively simple, only rice is planted, and there is no mixed breeding with other crops or fish, shrimp, etc., plus the long-term use of industrial fertilizers, Not only has it led to the degradation of soil resources, but also the disease resistance of rice has not been improved, and pests and diseases are more frequent. [0003] Chinese patent application No. 201610873807.5 discloses a method for symbiotic deworming of rice and grass carp, which includes the ...
