A method suitable for ecological utilization of straw in rice and shrimp fields in northern Jiangsu

Abstract

A method suitable for the ecological utilization of straw in rice and shrimp fields in northern Jiangsu, including the following steps: straw treatment, planting aquatic plants, and water regulation. The short-term deterioration of the water quality in the shrimp field has resulted in the death of Procambarus clarkii and its seedlings, causing major losses. By improving the method, quantity and utilization of straw returning to the field, water quality control, aquatic plant layout and benthic organism cultivation, etc. Technical measures have realized the full return of straw in rice and shrimp fields, zero discharge of water in the whole process, and more than 150Kg of Procambarus clarkii seedlings per mu.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method suitable for the ecological utilization of straw in rice and shrimp fields in northern Jiangsu. Background technique [0002] Straw returning to the field is an important link in the process of rice and shrimp breeding, and is the basis for realizing the ecological cycle. In the rice and shrimp breeding mode in northern Jiangsu, from late autumn to early spring (from mid-October to the end of April of the following year) is not only the time period for rice straw to be decomposed and returned to the field after harvesting, but also the time period for the breeding of broodstock and shrimp seedlings of Procambarus clarkii. During this period, if the method of straw returning to the field is unscientific, it is likely to cause the water quality of the rice and shrimp fields to deteriorate in a short period of time, resulting in the death of Procambarus clarkii and it...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problems in the background technology, the present invention studies a method suitable for the ecological utilization of rice and shrimp field straw in northern Jiangsu, and mainly solves the problem that the water quality of the rice and shrimp field may deteriorate in a short period of time when the straw in the rice and shrimp field is filled with water. , leading to the death of Procambarus clarkii and its seedlings, and causing major losses. By improving the way, quantity and utilization of straw returning to the field, and taking technical measures such as water quality control, aquatic plant layout and benthic organism cultivation, the straw in rice and shrimp fields can be realized. The whole amount is returned to the field, and the whole process is filled with zero discharge of water, and the average mu of Procambarus clarkii shrimp seedlings is more than 150Kg
