Problems solved by technology

In this patent, three rice varieties with close growth periods are selected for mixed sowing. Although the complexity of planting and field management is reduced to a certain extent, the rice yield is still low, less than 600kg / mu, and the genetic background of different varieties of rice Large differences lead to large differences in the quality and nutrition of rice, and the obtained rice has problems of uneven quality and nutrition

Embodiment 1

[0024] Embodiment 1 Based on high-quality indica rice Yangdao No. 6 rice mixed planting method

[0025] The basic variety selected in Example 1 is the high-quality indica rice "Yangdao No. 6" and its disease-resistant, insect-resistant, high-stem, multi-tiller mutant rice.

[0026] The basic variety "Yangdao No. 6" was bred by the Agricultural Science Research Institute of Lixiahe District, Jiangsu Province. It was approved by the Crop Variety Approval Committee of Jiangsu Province, Anhui Province, and Hubei Province in 1997, 2000, and 2001. A prominent mid-indica late-maturing conventional rice variety, which can be purchased from Jiangsu Lixiahe Regional Agricultural Science Research Institute.

[0027] The disease-resistant mutant rice "Zhemidao No. 1" is a rice with extremely compact plant type and strong resistance to sheath blight, which was bred by Zhejiang University's mutagenic Yangdao No. 6. It can tolerate high-density cultivation conditions and show increased yield...

Abstract

The invention discloses a rice companion planting method, comprises the steps of selecting a rice variety with excellent comprehensive characters as a basic variety and selecting mutants of different types from the basic variety as a match variety for companion planting, wherein at least one different excellent agricultural character exists among the mutants of different types; mixing the basic variety and the match variety, nursing seedlings and transplanting; performing field management and harvesting. According to the rice companion method, a rice group has multiple excellent agricultural characters, the resistance of the rice group to insect diseases is improved, the rice yield is improved and rice with uniform quality and nutrition can be obtained.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, in particular to a method for mixed rice cultivation. Background technique [0002] Mixed planting of rice biodiversity usually takes advantage of the difference in height and height between different rice varieties to fully coordinate light, temperature and fertilizer resources. Through mixed interplanting, the diversity of rice farmland varieties can be enriched, the ecological stability of farmland can be enhanced, the physiological quality of rice can be enhanced, the ability to resist diseases and insect pests can be improved, and the harm of diseases and insect pests can be effectively reduced. It not only reduces the amount of pesticides, but also reduces the pollution of agricultural products. It is an effective way to develop high-yield and high-efficiency agriculture at present. It is a practical technology for farmers to increase production, income and efficiency. It has very ...
