Embodiment 1

[0020] Embodiment 1 alfalfa and millet mixed sowing establishment

[0021] In 2011, in Arukorqin Banner, Chifeng City, Inner Mongolia, alfalfa and millet were mixed and planted. The variety of alfalfa is Aohan alfalfa (purchased from Beijing China Animal Science and Technology Co., Ltd., and the place of production is Aohan Banner, Chifeng City), and the variety of millet is the local variety of Alu Horqin Banner.

[0022] The specific planting method is as follows:

[0023] 1 site preparation

[0024] Because alfalfa seeds and millet seeds are small and have weak ability to top the soil, the land must be leveled and fined before sowing. Before the experiment, the stubble was plowed, and then the soil clods were broken with a disc harrow.

[0025] Base fertilizer (also known as basal fertilizer) plays an important role in ensuring the sustained high yield of alfalfa. Before plowing, apply 22.5 tons of organic fertilizer and 600 kg of superphosphate per hectare, and apply i...

Embodiment 2

[0034] Embodiment 2 alfalfa and millet mixed sowing establishment

[0035] In 2011, in Arukorqin Banner, Chifeng City, Inner Mongolia, alfalfa and millet were mixed and planted. See Example 1 for the varieties of alfalfa and millet.

[0036] The sowing row spacing is 30cm, and the sowing depth is 4cm. The amount of seeds used is 15.0 kg of alfalfa seeds per hectare, and the amount of mixed seeds is 3.0 kg of millet seeds per hectare. The sown area is 2 hectares. See embodiment 1 for the specific planting method.

[0037] Effect evaluation: the success rate of alfalfa planting in the sandy land was significantly improved, and all the test plots were successfully planted; the overwintering rate of alfalfa in the year of planting was significantly increased, and the overwintering rate in some plots increased by more than 20%; The yield of the first crop of alfalfa can be increased by more than 10%. The results of the field test are greatly affected by the local natural condi...

Embodiment 3

[0038] Example 3 Mixed planting of alfalfa and millet

[0039] In 2011, in Arukorqin Banner, Chifeng City, Inner Mongolia, alfalfa and millet were mixed and planted. See Example 1 for the variety of alfalfa, and the variety of millet is a local variety used by farmers in Aru Horqin Banner.

[0040] The sowing row spacing is 30cm, and the sowing depth is 3cm. The amount of seeds used is 15.0 kg of alfalfa seeds per hectare, and the amount of mixed seeds is 1.5 kg of millet seeds per hectare. The sown area is 2 hectares. See embodiment 1 for the specific planting method.

[0041]Effect evaluation: the success rate of alfalfa planting in the sandy land was significantly improved, and all the test plots were successfully planted; the overwintering rate of alfalfa in the year of sowing was significantly increased, and the overwintering rate in some plots increased by more than 20%; The yield of the first crop of alfalfa can be increased by more than 10%.

Abstract

The invention provides a method for sowing and planting alfalfa in the sandy field and particularly relates to a method for sowing and planting alfalfa and millet together. The alfalfa and the millet are not sowed in spring so that the environmental pollution caused by raised dust in spring is reduced and the growth of the seasonal alfalfa is not affected. The ground cover is formed in winter to increase temperature and preserve soil moisture, and annual grass seeds sowed together can not manure in the season so that the weeds can not obtained in the next year to affect the growth of the alfalfa. The stems of the grass growing up from the seeds sowed together are still upright when the grass turns green in the next year so that the wind speed and the raised dust on the surface of the sandy field are reduced. The stems of the grass are short so that the quality of the alfalfa harvested for the first time is not affected. The method has the advantage that the use frequency of the machine for large-area planting is not increased, and the method is very suitable for the large-area planting of the alfalfa in the sandy field.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a method for establishing and planting mixed sowing of alfalfa on sandy ground. Background technique [0002] Alfalfa is known as the king of pastures. It is a perennial leguminous pasture with high yield and nutritional value, and the crude protein content reaches more than 20%. Due to the small area of ​​arable land in our country and the problem of food security, it is impossible to plant alfalfa on a large scale in farmland. However, the demand for high-quality forage for the development of the dairy industry is increasing, and there is a huge domestic demand for high-quality alfalfa hay. demand, the current value of hay per ton has reached 2,200 yuan, and many northern sandy areas in my country have seen business opportunities and carried out large-scale alfalfa planting. On the one hand, it can prevent wind and fix sand, and on the other hand, it can provide high-quality...
