Embodiment 1

[0023] Zheyou No. 12 early indica rice was sown on April 15th and transplanted, and it was planted from May 12th to May 14th; from May 14th to June 10th, loach seedlings were stocked and loach feed was put in. Among them, loach The size of the seedlings is 80 / kg, and the stocking density is 100kg / 667m 2 ;From August 5th to August 10th, early indica rice was harvested; from August 10th to August 20th, fish fry were stocked, and the stocking density of fish fry was 25,000 / 667 m 2 , and put in fish feed; in October, catch loach and some fry, and catch mature fish, that is, those with a single fish weighing more than 2 catties are called mature fish, and the remaining smaller and immature fish continue to be raised until the next year In early April, it was harvested before the sowing of early indica rice.

[0024] The feeding time of loach feed and fish feed is the same, both are 8:00 in the morning and 17:00 in the evening, wherein the protein content in the loach feed is 38% (m...

Embodiment 2

[0027] On April 10th, Zhongjiazao No. 32 early indica rice was sown and transplanted. From April 25th to May 10th, it was planted; from May 14th to June 5th, loach seedlings were stocked and loach feed was put in. Among them, The specification of loach seedlings is 80 / kg, and the stocking density is 80kg / 667m 2 ; From July 15th to July 25th, early indica rice was harvested; from August 10th to August 20th, fish fry were stocked, and the fry stocking density was 30,000 / 667 m 2 , and put in fish feed; in October, catch mature fish and all loaches, that is, those with a single fish weighing more than 2 catties are called mature fish, and the remaining smaller and immature fish will continue to be cultured until the next year. In the first ten days of the month, it was caught before the sowing of early indica rice.

[0028] The throwing time of loach feed and fish feed is identical, is 8:00 in the morning and 17:00 in the evening, wherein protein content is 38% (mass ratio) in the...

Abstract

The invention discloses a rice-loach-fish coupling interplanting and crop rotation method, belonging to the technical field of culture condition improved water culture methods. The method comprises the following steps of: planting early indica rice, and transplanting; breeding loaches in a suitable place; harvesting the early indica rice; putting fish fries into the farmland; and capturing fishes and the loaches. The rice-loach-fish coupling interplanting and crop rotation method provided by the invention can be applied to the planting of rice and early rice and has the advantages of high yield, high quality, high benefit and the like.

Description

technical field [0001] The invention relates to a rice-loach-fish coupling intercropping rotation method, belonging to the technical field of hydroponic methods for improving cultivation conditions. Background technique [0002] Traditional agricultural production not only has low production efficiency and low income for farmers, but also relies on a large amount of pesticides and chemical fertilizers, causing a series of problems such as pesticide residues in rice fields, environmental pollution, rice quality decline, and increased resistance to pests and diseases. It is very fragile, which poses a serious threat to the sustainable development of agriculture and rural economy (Zhen Ruohong et al., 2004; Sun Gang et al., 2006). The extensive use of chemical fertilizers and pesticides in agriculture has excessively interfered with the rice field ecosystem, resulting in agricultural chemical pollution, which is extremely serious in many watersheds. The application of chemical...
