A kind of intercropping method of Chinese cabbage and forage oat

Abstract

The invention discloses a method for intercropping baby cabbage and forage grass oat. In particular, a baby cabbage and forage grass oat intercropping mode is adopted, so that field weeds growing at the seedling stage of baby cabbage can be restrained effectively, field closure of baby cabbage is reduced, the utilization ratios of the resources of light, temperature, water and soil are increased, and the yield of forage grass is increased. The method comprises the following steps: controlling inter-row weeds of the baby cabbage at the seedling stage of the baby cabbage by adopting forage grass oat, and preserving soil and water; selecting an upright forage grass oat variety having the characteristics of cutting resistance, high reproducibility and large leaf amount, cutting in time at the vegetative growth phase of oat, and controlling the stubble height to ensure regeneration of oat in order to avoid field closure of baby cabbage; harvesting the baby cabbage, scattering residual stems and leaves onto baby cabbage lines to realize straw turnover; after harvesting baby cabbage, applying urea in time to promote the growth of he oat, wherein the residual fertility of the baby cabbage lines can be effectively utilized by oat. By adopting the method, the problem of diseases of the baby cabbage caused by abnormal temperature in winter can be relieved, the spare seasons after the harvest of vegetables are effectively utilized, the popularization of the oat in winter fallow farmlands in southern areas is promoted, and forage grass supply in winter and spring in the herbivorous livestock in southern areas is ensured.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for intercropping Chinese cabbage and forage oats. Background technique [0002] As an excellent forage crop, forage-type oat has good palatability and feed value, and can be grazed and mowed. At present, we have successfully screened out mowing-resistant and strong regeneration varieties suitable for the hilly areas of Sichuan and Chongqing. Winter planting of forage oats is a winter agricultural model with broad prospects for promotion in the south, which effectively alleviates the shortage of forage grass caused by the rapid development of large-scale herbivorous animal husbandry represented by the dairy industry in the south. The economic benefits of grass are relatively low, and farmers are not motivated to produce. [0003] Winter vegetables are an important mode of high-efficiency agriculture in the hilly areas of Sichuan and Chongqing in winter. D...

Winter planting of forage oats is a winter agricultural model with broad prospects for promotion in the south, which effectively alleviates the shortage of forage grass caused by the rapid development of large-scale herbivorous animal husbandry represented by the dairy industry in the south. The economic benefits of grass are relatively low, and farmers are not motivated to produce

[0003] Winter vegetables are an important mode of high-efficiency agriculture in the hilly areas of Sichuan and Chongqing in winter. Due to the relatively short growing season of vegetables, there are often 2-3 months of idle time that cannot be effectively utilized after the harvest of vegetables and the sowing of spring crops. At the same time, there are many cloudy and rainy weather in autumn and winter in this area, and the problem of weeds in the field of Chinese cabbage is serious: the temperature in this area changes greatly in winter, and the field of monocropping Chinese cabbage is severely closed. virus disease etc.
