2022-12-18 04:05:15
In recent years, with the rise of grass heat in the country, planting grass and raising livestock has become an important part of the restructuring of the agricultural planting industry. The area of ​​grass has been continuously expanding, and grass-eating livestock and poultry have developed rapidly, starting from “agricultural efficiency increase and farmers’ income increaseâ€. A certain role. However, the cultivation of pasture has a certain degree of scientificity. There are still many misunderstandings about how to plant good grass and raise good livestock. Now we will briefly discuss several issues that should be noted:
First, the selection and treatment of pasture seeds
The selection and treatment of pasture seeds is a prerequisite for the success of forage cultivation. The following points should be noted: 1. Forage seeds should be selected from more than two qualified seeds, without moldy, degenerate seeds. 2. Remove impurities, insufficient seeds and weed seeds before planting. 3. Spread the seeds before planting and soak in the sun for 2-3 days before sowing to promote the ripening of the seeds, break the dormancy of pasture seeds, and increase the germination rate. 4, soaking with warm water, so that the seeds fully absorb water, speed up the germination germination. 5. The use of pesticide seed dressing can prevent birds and soil pests from eating pasture seeds and prevent some diseases (such as smut and smut of grasses). 6, some leguminous hard seeds (red clover, white clover, alfalfa) due to seed coat outside a layer of dense columnar stone cells, water is not easy to immerse, must be scratched seed coat to increase the germination rate. 7. The initial cultivation of leguminous grasses must be vaccinated with dedicated rhizobial bacteria to increase the yield of pasture.
Second, the choice of pasture planting plots
Forage planting is not the same as crop planting. There are certain requirements for the selection of plots. First, the acidity and alkalinity of the land must be consistent with the biological characteristics of pasture. For example, alfalfa needs to be alkalined, and the soil with too much acid can't be planted; second, it can't use low-lying fields with stagnant water. Most pastures are not tolerant to moisture, such as plots that are too low, and it is prone to rot-root dead seedlings after rain. Therefore, land plots with a slightly lower terrain must be excavated and drains should be cleared in time to prevent wet damage.
Third, the sowing time of pasture
To determine the appropriate time for pasture sowing, should consider the following aspects: First, the type of pasture, the pasture is a cold season or pasture season grass, usually grain pods, bitter vegetables, Pennisetum, Ning Hybrids No. 3 and No. 4 can only be sowed in spring. When the ground temperature exceeds 10° C. in the spring sowing, the area south of the Yangtze River is in early April, Huanghuai area is in mid-April, and the area north of the Yellow River is in the middle-late April. sowing. Lolium multiflorum, winter rye 70, wolfberry fruit, and grass hibiscus are only suitable for autumn sowing. The suitable time for the area south of the Yellow River is September. Rumex K-1 hybrid sorrel, alfalfa, red clover and white clover can be sown in spring as well as in autumn. The second is the climatic factor. Grass sowing should avoid continuous rainy weather and dry seasons. It is best to sow the seed on the second day after the rain stops.
Fourth, livestock and poultry common herbage supply and feeding issues
What kind of herbivores and livestock are not planted indiscriminately? In order to ensure that the cultivated pasture is suitable for the taste of livestock and poultry, and to meet the needs of the pasture throughout the year, the common pasture planting patterns are as follows:
