New ecological and cycling cropping-breeding mode for continuous cropping of crawfish, paddy rice and precocious Chinese cabbages

Abstract

The invention provides a new ecological and cycling cropping-breeding mode for continuous cropping of crawfish, paddy rice and precocious Chinese cabbages. The mode is characterized in that after finishing catching crawfish in the field, one-season quality rice can be planted according to an organic planting mode; after harvesting of rice, one-season precocious Chinese cabbages are planted; by adjusting the sowing period of precocious Chinese cabbages, flowering Chinese cabbages are harvested in the parcels of the field four to five times from Spring Festival to the following year; the reminders of flowering Chinese cabbages can be used as fodder for crawfish; and the reminders of crawfish that is eaten can be used as green manure. The new ecological and cycling cropping-breeding mode for continuous cropping of crawfish, paddy rice and precocious Chinese cabbages has the following beneficial effects: resources of parcels in the field can be fully used; the multiple crop index is increased while culture cost is saved; the reminders of Chinese cabbages that are eaten by crawfish can be used as organic fertilizers so that the content of organic matter in soil is improved; the cropping-breeding mode is high in benefit, low in production cost and high in utilization of parcels in the field; the ecological benign cycle is formed; and the green, eco-friendly and low-carbon cropping-breeding mode for crawfish in the field is formed.

Description

technical field [0001] The invention relates to the field of ecological breeding, in particular to a new mode of continuous cropping ecological circulation of shrimp, rice and early-maturing cabbage. Background technique [0002] The comprehensive farming mode of shrimp and rice co-cropping adopted by farmers is mainly characterized by low investment, low risk, short cycle, quick effect, good benefit and easy operation. Taking shrimp and rice as an example, the yield of high-quality rice per mu (organic rice quality) is about 500kg, and the income of shrimp is increased. Generally, the yield of crayfish per mu is 75-100kg, and the yield of cabbage and cabbage is more than 500 kg. The total output value per mu is 7000-9000 yuan, and the net profit per mu More than 3,500 yuan, which is more than 3,000 yuan more than the net income per mu of ordinary rice planting. [0003] In recent years, the demand for crayfish in the domestic market has been increasing day by day, showing ...

Problems solved by technology

[0005] However, the ordinary shrimp and rice breeding mode has the problem that the farmland is idle for about 3 and a half months after the rice is harvested and before the field is watered in the second year. The farmland is idle for a long time and the resources are not fully utilized.
