A kind of intercropping method of children's cabbage and multi-flowered ryegrass

Abstract

The invention discloses a baby cabbage and Italian ryegrass intercropping method, and particularly relates to a baby cabbage and Italian ryegrass intercropping mode through which field weeds growing at the baby cabbage seedling stage are restrained, the baby cabbage field crown closure is reduced, the climate and land resource utilization rate is increased, and forage grass yield is increased. The Italian ryegrass is utilized at the baby cabbage seedling stage to control the baby cabbage field weeds and conserve water and soil, the strong regeneration capability of the Italian ryegrass after mowing is utilized, the Italian ryegrass is mowed in time, and baby cabbage field ventilation is guaranteed. The residual steam leaves are laid on baby cabbage ridges after the baby cabbage is harvested, and the straw mulching is achieved. After the baby cabbage is harvested, dressing of urea is carried out in time according to the nitrophilous characteristic of the Italian ryegrass, the growth of the Italian ryegrass is promoted, and the land resources are effectively utilized. After the baby cabbage is harvested, the Italian ryegrass can effectively absorb the manure on the baby cabbage ridges through the developed root system of the Italian ryegrass. The baby cabbage and Italian ryegrass intercropping method can solve the problem of the plant disease, caused by the abnormal winter temperature, of the baby cabbage, the forage grass yield can be increased by effectively utilizing the free seasons after the baby cabbage is harvested, and meanwhile the forage grass supplying of the southern herbivorous animal husbandary in winter and spring is guaranteed.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for intercropping Chinese cabbage and multiflora ryegrass, in particular to an intercropping mode of Chinese cabbage and multiflora ryegrass. Background technique [0002] Taking advantage of climate resources in southern my country to vigorously develop winter agriculture and effectively develop and utilize winter fallow fields is an effective way to increase farmland output and alleviate the pressure on food security in the south. Winter planting of multiflora ryegrass is a winter agricultural model widely promoted in the south, which can effectively alleviate the shortage of forage grass caused by the rapid development of herbivorous animal husbandry. However, due to the low economic benefits of planting grass, farmers are not very enthusiastic about production. [0003] Winter cabbage is an important mode of high-efficiency agriculture in the hilly area...

Winter planting of multiflora ryegrass is a winter agricultural model widely promoted in the south, which can effectively alleviate the shortage of forage grass caused by the rapid development of herbivorous animal husbandry. However, due to the low economic benefits of planting grass, farmers are not very enthusiastic about production

[0003] Winter cabbage is an important mode of high-efficiency agriculture in the hilly areas of Sichuan and Chongqing in winter. Because the growing season of cabbage is relatively short, there are often 2 to 3 months of idle time between the harvest of cabbage and the sowing of spring crops, which cannot be effective At the same time, there are many rainy weather in autumn and winter in this area, and the problem of weeds in the vegetable field is serious: the temperature in this area changes greatly in winter, and the canopy is serious in the field of vegetable crops. When encountering a sudden increase in temperature, it is very easy to have rotten roots, excessive growth, virus disease etc.
