Culture method of vegetable interplanting in rapeseed plants in mountain area zone

Abstract

The invention discloses an efficient culture method of vegetable interplanting in rapeseed plants in a mountain area zone. The rapeseed varieties with strong individual advantages and great yield increase potential are selected; the big and strong seedlings are cultured in advance; board and narrow plane distance ultralow density transplanting is used; vegetable varieties which can be harvested before the rapeseed plant bolting and cannot cause damage on the land during the harvesting are selected and are interplanted between rapeseed plants with wide rows and plant distances at the same period; sufficient base fertilizers are used; organic fertilizers are used as major fertilizers; composite inorganic fertilizers are matched; the top application is performed in time; according to the seedling condition, leaf fertilizers are properly sprayed; the prevention and treatment on plant diseases and insect pests are well made. By aiming at the problems of terrain, climate, human resources andthe like in the mountain area zone, the invention comprehensively provides a culture mode; the individual production potential of the rapeseed plants is sufficiently achieved; the single plant effectpod number is greatly improved; the group effective pod number is ensured; the rapeseed plant yield increase and yield stabilization are realized; the vegetables are interplanted in gaps of the rapeseeds; the bare land before the row sealing is reasonably utilized; the income of one season vegetable can be increased; the rapeseed planting benefits and field block utilization efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and relates to a cultivation method for interplanting rapeseed vegetables in mountainous areas. Background technique [0002] Rapeseed is the largest oilseed crop in my country, with an average annual planting area of ​​about 7 million hectares. The main production areas of rapeseed in my country are mainly concentrated in the Yangtze River Basin. [0003] The mechanization of the whole process of sowing and harvesting is the mainstream direction of rapeseed breeding and cultivation in recent years. Rapeseed direct seeding increases the planting density, generally 350,000 to 500,000 plants / hm 2 , so that the rape plants become shorter, the stems become thinner, and the maturity period is relatively consistent, which is suitable for mechanical harvesting. Sichuan, Chongqing, Yunnan, and the southwestern part of Hubei, which are located in the middle and upper reaches of the Yangtze Rive...

AI Technical Summary

Problems solved by technology

However, traditional seedlings are transplanted, and the transplanting density is 90,000 to 120,000 plants / hm 2 , the transplanting process is labor-intensive. Before flowering, it is necessary to keep the middle and lower parts of the rapeseed ventilated and light-transmitting by threshing leaves, and the economic benefits are low. In recent years, when a large number of migrant workers go out to work and the shortage of rural labor force, farmers' enthusiasm for planting rapeseed has been declining.
