Ratoon rice storage cultivation method suitable for southern rice-fish symbiotic system

Abstract

A ratoon rice storage cultivation method suitable for a southern rice-fish symbiotic system comprises the steps of field treatment, wherein 75 kg of quick lime is applied to each mu for sterilization, 500 kg of organic fertilizer is applied, 40 kg of ternary (N15, P15, K15) compound fertilizer is applied, and then ploughing is conducted for transplantation preparation; placing fries after transplantation, wherein after rice seedlings are transplanted for 7-10 days, rice fish fries are put in; managing first rice crops, wherein as the rice seedlings and fries grow, water level is increased, and after rice matures, rice is harvested with water left and proper straw height reversed for ratoon rice growth; managing ratoon rice, wherein after first rice crops are harvested, pests are controlled and leaf fertilizer is applied in time, harvesting is conducted when ratoon rice matures by 90%, and rice fish is harvested. By the adoption of the method, annual yield of rice is increased greatly, rice-fish symbiotic time is prolonged, the positive rice-fish symbiotic effect is fully realized, resource utilization efficiency is improved, production and income are increased, the nation and the people are benefited, and economy-society-environment joint development is achieved.

Description

technical field [0001] The invention relates to the technical field of rice regeneration cultivation and paddy field cultivation, in particular to a regeneration rice storage and cultivation method suitable for the southern rice-fish symbiosis system. Background technique [0002] Fish farming in rice fields has a long history in China and has a large scale of production in southern rice areas. The rice-fish symbiosis system located in the southern mountainous area of ​​Zhejiang Province has existed widely in Lishui Qingtian, Jingning, Longquan, Wenzhou Yongjia, Ruian, etc. for at least 1,200 years. The Qingtian rice-fish symbiosis system was listed in the first batch of global important Agricultural cultural heritage (GIAHS) has multiple meanings of society, economy, ecology, politics and culture. Rice-fish symbiosis uses rice and field fish ecological breeding, which is a typical model of paddy-fish farming suitable for the natural conditions in hilly areas. Rice is used ...

Problems solved by technology

Judging from the production practice in the past few years, there is still room for innovation and reform in the rice-fish symbiosis system, that is, the heat conditions of single-crop rice-fish symbiosis rice have not been fully utilized after harvesting, an
