Efficient and green polyploid rice, taro, frog and loach co-breeding ecological system

Abstract

The invention provides an efficient and green polyploid rice, taro, frog and loach co-breeding ecological system. The efficient and green polyploid rice, taro, frog and loach co-breeding ecological system is characterized by comprising steps of a, carrying out field planting on polyploid rice fine varieties; b, growing taro improved varieties on ridges of rice fields; c, erecting insect frequencyoscillation trapping and killing lamps in the air; d, moderately artificially introducing and naturally immigrating sufficiently multiplied insect pests and natural enemies between rice and allowing the insect pests and natural enemies to live on rice plants; e, breeding frogs and loach under the rice; f, forming the efficient and green polyploid rice, taro, frog and loach co-breeding ecological system. The efficient and green polyploid rice, taro, frog and loach co-breeding ecological system is based on the outstanding polyploid rice and is centered on whole-course stereoscopic biocontrol, and the rice, taros, the frogs and the loach are harvested products of the efficient and green polyploid rice, taro, frog and loach co-breeding ecological system. The efficient and green polyploid rice,taro, frog and loach co-breeding ecological system has the advantages that stereoscopic control and full-green production can be comprehensively implemented if the efficient and green polyploid rice,taro, frog and loach co-breeding ecological system is applied, chemical pesticides are omitted in whole course, and accordingly harmful effects of the chemical pesticides on production, human bodiesand environments can be prevented; the high-quality and high-value products such as the high-grade rice, the improved-variety taros, the hybrid frogs and the superior-variety loach can be harvested, agricultural product types can be enriched, and the production benefit can be increased.

Description

technical field [0001] The invention relates to the construction of a highly efficient and green polyploid rice, taro, frog and loach co-cultivation system, belonging to the technical field of ecological agriculture of modern agriculture. Background technique [0002] my country has a population of more than 1.3 billion, and the current food self-sufficiency rate is 80% to 85%. In recent decades, since the advent of the hybrid rice Shanyou 63, the increase in rice production has been less than 1% per year. It is far from meeting the requirement of increasing production by 5% between 2030 and 2050. How to ensure food security and food safety is of great significance, but it is very difficult. For this reason, Cai Detian, Yuan Longping, and Lu Xinggui proposed a new strategy of "breeding super rice using the dual advantages of distant hybridization and polyploidy", which is not only a new way to develop evolutionary breeding, but also has the ability to pass wild diploids lik...

AI Technical Summary

Problems solved by technology

[0003] After 20 years of research, after overcoming the bottleneck problem of low seed setting rate of polyploid rice and breeding two polyploid meiotic stability (PMeS) high-fruiting lines, more than 5,000 polyploids have been bred Materials, more than 200 excellent strains, more than 10 strains that can apply for regional trials, but still meet the food demand of population development

[0004] A large number of chemical fertilizers, pesticides, fungicides and herbicides are used in my country's existing grain production, which affects environmental safety
