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

[0021] 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 , the stocking density of frog seedlings is 2000 / 667 m 2 ; From July 5th to July 10th, early indica rice is harvested; in October, loach and mature frogs are captured, and the remaining smaller and immature frogs continue to be raised until early April of the following year, before the early indica rice is sown. capture.

[0022] The throwing time of loach feed and frog feed is identical, is 8:00 in the morning and 17:00 in the evening, wherein protein content is 38% (mass ratio) in the loach feed, and the daily feeding amount of loach feed accounts for loach gross weight 1.5%; The protein content in the frog feed is 50%, and the daily feeding amount of the frog feed is 40% h...

Embodiment 2

[0025] On April 10, Zhongjiazao No. 32 early indica rice was sown and transplanted, and it was planted from April 25 to May 10; from May 14 to June 5, loach seedlings and frog seedlings were stocked, and loach feed was put in and frog feed, among which, the size of loach seedlings is 80 / kg, and the stocking density is 80kg / 667m 2 , the stocking density of frogs is 4000 / 667 m 2 ; From July 15th to July 25th, early indica rice was harvested; in October, mature frogs and all loaches were captured. The mature frogs were called autumn frogs, and the rest of the smaller and immature frogs continued to be raised until the next year's April. In the first ten days of the month, before the sowing of early indica rice, the frogs caught at this time are spring frogs.

[0026] The throwing time of loach feed and frog feed is identical, is 8:00 in the morning and 17:00 in the evening, wherein protein content is 38% (mass ratio) in the loach feed, and the daily feeding amount of loach feed ...

Abstract

The invention discloses a rice-loach-frog coupling intercropping crop rotation method, belonging to the technical field of cultivation condition improvement by a hydroponic method. The rice-loach-frog coupling intercropping crop rotation method comprises the following steps of: sowing and planting early indica rice; transplanting; breeding loaches and little frogs; feeding the frogs and the loaches; harvesting the early indica rice; and capturing the frogs and the loaches. The rice-loach-frog coupling intercropping crop rotation method can be applied to rice and early season rice cultivation and has the advantages of high yield, good quality, good benefits and the like.

Description

technical field [0001] The invention relates to a rice-loach-frog 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...
