Method for increasing cropping index while improving tomato breeding field soil

Abstract

The invention provides a method for increasing a cropping index while improving tomato breeding field soil. The method comprises the steps that in a solar greenhouse, a matrix is placed in a seedling disc, tomatoes are sown, and the seedling disc is covered with the matrix and a plastic film sequentially after sowing; after 80 percent of seed leaves come up, the plastic film is removed, and tomato seedlings continue to be cultivated; after the tomato seedlings grow with two leaves and one core, flat furrows are arranged outside the solar greenhouse in the east and west direction, the tomato seedlings are transplanted to the flat furrows, and the flat furrows are provided with an arch shed covered with double layers of plastic films; after the tomato seedlings grow with the plant height ranging from 20 cm to 30 cm, the tomato seedlings are planted to a plurality of cultivation furrows, two ears of inflorescences are reserved for each tomato seedling, and cultivation continues after pinching, wherein the distance between every two adjacent cultivation furrows ranges from 35 cm to 45 cm; after the tomato seedlings bloom and bear fruit, corns are interplanted between the cultivation furrows. According to the method, the cropping index can be increased, the land utilization efficiency can be improved, and the soil is improved.

Description

technical field [0001] The invention relates to the field of breeding, in particular to a method for improving the soil of a tomato breeding field while increasing the multiple cropping index. Background technique [0002] In the process of tomato breeding material separation and generation selection, a large amount of land is used. In the case of limited land for selection, continuous cropping is carried out for many years, resulting in obstacles to continuous cropping, which makes tomato prone to viral diseases, and tomato planted in the open field is prone to sunburn. How to improve the economic benefits of breeding fields on the basis of improving soil, reduce breeding costs, improve land use efficiency, prevent sunburn and reduce the occurrence of viral diseases are of great value to material selection for tomato breeding. [0003] At present, measures to improve soil include: crop rotation, which requires a large amount of land; high-temperature disinfection of soil is...

Problems solved by technology

[0003] At present, measures to improve soil include: crop rotation, which requires a large amount of land; high-temperature disinfection of soil is costly; improving soil texture is labor-intensive and time-consuming

The main disadvantages of the above measures are firstly that crop rotation cannot be carried out in the case of limited land, and secondly, it is only one-sided prevention and control of diseases and insect pests, which increases the cost of scientific research and has no obvious effect on improving soil structure or nutrient composition.

Therefore, it is impossible to improve the soil while improving the multiple cropping index, prevent tomato sunburn and reduce the occurrence of viral diseases
