Embodiment 1

[0050] The test site is located in the hilly and dry slope land of Wushe, Gaogu Village, Dingjia Town, Bishan County, Chongqing City, with sandy loam soil, soil organic matter content of 21.53g / kg, total nitrogen 1.46g / kg, total phosphorus 0.37g / kg, total potassium 16.13g / kg kg, alkaline hydrolysis ammonia 137.33mg / kg, available phosphorus 2l.00mg / kg, available potassium 33.00 mg / kg, the previous crop was corn, and decomposed cow dung was applied for 3 consecutive years.

[0051] The experiment set up 6 treatments:

[0052] Treatment 1, oat monoculture (row spacing 30cm, seeding rate 120kg / hm 2 ):

[0053] Treatment 2, child menu operation (row spacing is 60cm, point spacing is 50cm);

[0054] Treatment 3, 1 row of vegetable intercropping and 2 rows of oats (the hole distance of vegetable is 50cm; the row spacing of oats is 30cm, the actual sowing area is 120kg / hm 2 ;The distance between children's vegetables and oats is 50cm);

[0055] Treatment 4, 4 rows of oats intercro...

Embodiment 2

[0064] The production site is located in the hilly slopes of Gaogu Village, Dingjia Town, Bishan County, Chongqing City, in a paddy and dry rotation field, and the previous crops are rice and sandy loam. A large-scale production comparison was made between single-planting vegetables and "two rows of vegetables intercropping four rows of oats". The row spacing of the menu is 60cm, and the hole spacing is 50cm; 2 rows of vegetables are intercropped with 4 rows of oats, the row spacing of vegetables is 60cm, the hole spacing is 50cm, the row spacing of oats is 30cm, and the actual sowing area is 120kg / hm 2 The distance between children's vegetables and oats is 50cm. The production area of ​​both modes is 0.3hm 2 . The variety of Ercai is an early-maturing local variety in Dingjia Town, Bishan County, and the variety of oats is "Baiyan No. 7". On September 5, 2012, the seedlings were sown; on October 10, the nests were opened and oats were sown; on October 20, when the seedling...

Embodiment 3

[0069] The production site is located in a long-term vegetable field in Taichuan District, Chongqing City. It is a summer fallow, purple soil, and medium fertility. For 5 consecutive years, it has been only grown as a vegetable in winter, and viral diseases have occurred seriously. A large-scale production comparison was made between single-planting vegetables and "two rows of vegetables intercropping four rows of oats". The row spacing of single cropping vegetables is 60cm, and the spacing of holes is 50cm; the pattern of intercropping 2 rows of vegetables and 4 rows of oats is 60cm, the spacing of holes is 50cm, the row spacing of oats is 30cm, and the actual sowing area is 120kg / hm. 2 , The distance between children's vegetables and oats is 50cm. The production area of ​​both modes is 0.5hm 2 . The variety of Ercai is an early-maturing local variety in Dingjia Town, Bishan County, and the variety of oats is "Baiyan No. 7". On September 10, 2012, the seedlings were sown; ...

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...
