Description
The feeding value of Vetch vetch is equivalent to that of Vetch vetch. Cows, sheep, pigs and rabbits are all fond of food. Green feed is dominated in agricultural areas in my country. It is used as hay or silage in the United States, and also as green forage or grazing. Harvested at the budding stage, the yield of fresh grass per mu is 2000-3500kg. If harvested in stages, the lower leaves can be prevented from yellowing or mildew due to thick grass, and the grass is relatively tender. In the Jianghuai area, if sowing in September, it can be harvested in late March and early May. If the planting surface grows well in mid-August, it can be harvested in winter, early spring and early summer, or it can be densely planted. The harvesting is done in batches to increase the frequency and output of harvesting. Forage quality is higher before budding stage, with chemical composition shown in Table 74. According to the analysis of the grassland workstation in Liangshan Prefecture, Sichuan, the crude protein in the dry matter of the whole grass reached 30.69%, the crude fat 9.7%, the crude fiber 22.82%, the nitrogen-free extract 28.05%, and the crude ash during the branching stage. 8.74%, calcium 1.48%, phosphorus 0.24%. Vetch vetch is also a good green manure and cover crop. Its hard seeds (usually 10-15%) can be used to grow spontaneously every autumn in the orchard, and cover in March to June. It can also be used as a pioneer crop for reclaiming wasteland. It has a good effect of suppressing weeds and improving soil. When it is used as green manure in farmland, it is the pre-crop of rice, cotton, corn and other crops. The composition of fresh grass fertilizer is as follows: total nitrogen 0.50%, phosphorus pentoxide 0.13%, potassium oxide 0.43%. Vicia glabra is also a good nectar plant, with a flowering period of up to 1 month and good nectar quality. 1 mu can provide about 25kg of nectar.
