Problems solved by technology

The application of chemical fertilizers and pesticides also greatly reduces the quality and safety of crops, causing great harm to human health, such as the occurrence of cancer (Dich et al., 1999)
Although there is a method of mixing fish and rice in the existing ecological polyculture methods, the fish fry have relatively harsh requirements on the breeding conditions, especially when the rice is harvested, it still needs continuous water supply, which is a serious waste of water resources and fish prices. The rise is limited, and the future economic outlook is not ideal

Embodiment 1

[0023] Zheyou 12 early indica rice was planted on April 15 and transplanted, and planted from May 12 to May 14; loach seedlings were stocked from May 14 to June 10, and loach feed was put in, among them, loach The size of the seedlings is 80 / kg, the stocking density is 100kg / 667m 2 ; From August 5th to August 10th, harvest early indica rice; from August 10th to August 20th, stocking green prawns, the stocking density of green prawns is 30,000 / 667 m 2 And put shrimp feed; in October, catch loach and some blue prawns, catch mature blue prawns, that is, autumn prawns. The remaining smaller, immature blue prawns will continue to be cultivated until early April of the following year, and planted in early indica rice. The green prawns caught at this time are spring prawns.

[0024] Loach feed and shrimp feed are put in at the same time, both at 8:00 in the morning and 17:00 at night. The protein content of the loach is 38% (mass ratio), and the daily feeding amount of the loach accounts...

Embodiment 2

[0027] Zhongjiazao 32 early indica rice was sown on April 10 and transplanted, and planted from April 25 to May 10; loach seedlings were stocked from May 14 to June 5, and loach feed was put in, among which, The size of the loach seedlings is 80 / kg, and the stocking density is 80kg / 667m 2 ;July 15th to July 25th, harvest early indica rice; August 10th to August 20th, stocking blue prawns, the stocking density of blue prawns is 35,000 / 667 m 2 And put shrimp feed; in October, catch mature blue prawns and all the loach, mature blue prawns are autumn shrimps, and the remaining smaller, immature blue prawns will continue to be cultivated until early April of the following year, in early indica rice Caught before planting, the green prawns caught at this time are spring prawns.

[0028] Loach feed and shrimp feed are put in at the same time, both at 8:00 in the morning and 17:00 at night. The protein content of the loach is 38% (mass ratio), and the daily feeding amount of the loach acc...

Abstract

The invention discloses a rice-loach-shrimp 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 freshwater shrimps into the farmland; and capturing the freshwater shrimps and the loaches. The rice-loach-shrimp 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-mahi-shrimp coupled intercropping cultivation 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 number of pesticides and fertilizers for agricultural production. This has caused a series of problems such as pesticide residues in rice fields, environmental pollution, degradation of rice quality, and increased resistance to pests and diseases, which has changed the structure and function of farmland ecosystems. 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). A large number of chemical fertilizers and pesticides are used in agriculture, which excessively interferes with the rice field ecosystem, cau...
