Embodiment 1

[0027] (1) Planting environmental conditions: The experiment was carried out from July 25 to October 15, 2014 in Songshan District, Chifeng City, Inner Mongolia Autonomous Region. The area has a temperate semi-arid continental monsoon climate with four distinct seasons, annual sunshine hours of 2,800-3,100 hours, annual average temperature of 4-7°C, frost-free period of 120-145 days, and accumulated temperature of ≥10°C of 1,800-3,000°C·d. The terrain of the test site is flat, with good light and ventilation conditions. The soil available nitrogen is 50.89mg / kg, the available phosphorus is 22.99mg / kg, the available potassium is 70.56mg / kg, and the soil organic matter is 9.23g / kg;

[0028] The experimental multi-planting area is 9 mu, and the non-replanting summer and autumn idle land is used as the control, which is close to the experimental multi-planting plot, with an area of ​​9 mu, and the climate and soil conditions are the same as the multi-planting plot. The cultivated ...

Embodiment 2

[0048] (1) planting environmental conditions: with embodiment 1. The test area of ​​multiple cropping is 9 mu, and the area of ​​control without multiple cropping is also 9 mu. The cultivated wheat varieties and cultivation management of the previous stubble are the same;

[0049] (2) Soil preparation: 3 days after the harvest of spring wheat, use a tiller to carry out deep plowing, 30cm deep plowing, and then use a disc harrow to harrow and grind the land to form a soft and fine cotton soil condition with empty top and solid bottom bottom;

[0050] (3) Irrigation: Irrigate after site preparation, and the irrigation depth reaches 30cm in the soil layer;

[0051] (4) Drying: After irrigation, dry for 2 days, so that the water can fully penetrate into the soil plow layer, so that the soil can not stick to hands and the surface is not dry before sowing;

[0052] (5) Seed selection: Qingyan 1 and Linna were selected as oat varieties;

[0053] (6) Sowing: Sowing on July 29; using...

Abstract

The invention discloses a method for planting oat in a spring wheat field vacant in summer and autumn. According to the method for planting oat in the spring wheat field vacant in summer and autumn, through a series of technical means such as soil preparation, irrigation, sun-curing, seed selection, sowing, field management and harvesting, the problems that due to the fact that the spring wheat field is vacant in summer and autumn, the land utilization rate is low, cultivated land waste is caused, the soil moisture status deteriorates, and conflict between grass and livestock is caused are solved, grain is grown in the spring wheat field in spring, grass is grown in the spring wheat field in summer and autumn, the light resource, heat resource and water resource are fully utilized, the multiple crop index and land equivalent are increased, the contradiction between people and land is relieved, the land utilization rate can be increased, the soil water content and soil nutrient content are increased, high-quality forage is provided for the development of animal husbandry, the yield of high-quality oat hay can be 600-800 kg/667 m<2>, economical benefits can be increased, and compared with the prior art that multiple cropping is not conducted, the net income can be increased by 580-900 yuan per mu.

Description

technical field [0001] The invention relates to a multi-cropping production mode of planting grain in spring and grass in summer and autumn, in particular to a method for multi-cropping oats in spring wheat fields in summer and autumn. Background technique [0002] China's spring wheat planting areas are mainly distributed in Xinjiang, Gansu, Qinghai, Ningxia, Inner Mongolia, Jilin, Heilongjiang and other northern mid-to-high latitudes and relatively high altitude areas, which are areas with more than one season and less than two seasons. The planting area of ​​spring wheat in my country shows a downward trend year by year, the idle land in summer and autumn is underutilized, and the planting income is small. In the "13th Five-Year Plan" agricultural science and technology, among the problems to be solved, it is proposed to realize the goal of expanding the area of ​​cultivated land and agricultural land by excavating and utilizing the existing cultivated land. The light an...
