Problems solved by technology

[0005] The purpose of the present invention is to provide a new method for mixed planting of rice varieties, which realizes mechanized planting through mixed seedling raising and mechanical transplanting of varieties, thereby realizing mixed planting of rice in the true sense, with reduced workload, easy operation, and lower production costs than manual ones. The planting can be greatly reduced; at the same time, the orderly planting of seedlings by machine transplantation solves the problems of uneven seedling emergence in mixed direct seeding, difficulty in group disorder regulation, shallow root growth of plants, and premature aging and lodging in the later stage, so as to increase production and efficiency, which is beneficial to Large-scale promotion and application

Abstract

The invention belongs to the technical field of rice planting, in particular to a rice yield increasing planting method which increases the yield through intervarietal mixed cultivation. According to the rice yield increasing planting method, rice varieties with different resistance properties are fully combined to form a stable ecological system suitable for rice to survive, and the high yield of rice is realized through potential maximization. According to the rice yield increasing planting method, rice varieties with similar growth periods, similar agronomic traits and different resistance properties are selected for raise rice seedlings, and then the rice seedlings are mechanically transplanted at the same period. The different resistance properties of the rice varieties interact to give full play to the production potential of all the rice varieties; meanwhile, a three-dimensional community is built, so that stability of a field ecological system is improved, common diseases, pests and weeds are effectively controlled without applying pesticides or applying a small number of pesticides, and green production of rice is realized.

Description

technical field [0001] The invention belongs to the technical field of rice planting, and specifically relates to a method for increasing yield through mixed cultivation among varieties. The method fully combines the resistance of different rice varieties to form a stable and suitable ecosystem for rice survival , to achieve high rice yield by maximizing potential. Background technique [0002] Rice production is of great significance to ensuring food security in my country. With the rapid development of my country's economy and the increasing level of science and technology, new varieties of rice continue to emerge, and the output has been greatly increased. However, due to the selection and breeding of excellent varieties, the local varieties continue to decrease, which reduces the genetic diversity of rice, and the quality traits tend to be the same, and the outbreak of diseases, insect pests and weeds is easy to occur. Dramatic decline in biodiversity of rice population...
