Knowledge Introduction: In recent years, grasslands and livestock have developed rapidly. Farmers regard grass as a grain species, and use grass as a food source to obtain considerable economic benefits. This has become the current trend in the adjustment of agricultural industrial structure. If we can correctly grasp the technology of pasturage and animal husbandry, it will be beneficial to improving the efficiency of planting grass, increasing the income of farmers, protecting the ecological environment and promoting the production of pollution-free livestock products.
1. Choose excellent grass for planting. It is necessary to grow high-quality pasture varieties that have strong adaptability, high nutritional value, high yield, and have been cultivated artificially. When purchasing seed, it is necessary to purchase it in a place where it is specialized in supplying grass seeds, and to learn about pasture variety introduction, cultivation techniques, and pest and disease control.
2. Because of different livestock, choose different pasture varieties. When feeding different livestock and poultry, according to their different eating habits and digestive characteristics, they should choose suitable forage species. Pigs are omnivorous animals, like to eat tender and juicy leafy pasturage, such as grain pods, bitter leeks, pine cone herbs, chicory, etc.; cattle as herbivorous large livestock, good sperm tolerance, large appetite, hi Forage herbivores, ryegrass, hybrid pennisetum, sudangrass, imperial bamboograss, etc. should be planted; sheepskins should eat short and dry pastures, and ryegrass, tall fescue, white clover and alfalfa should be planted; Rabbit loves foliar pastures, suitable for planting ryegrass, grain pods, hairy wolfberry fruit, red and white clover, etc.; goose leafy vegetables with less stems or leguminous plants, suitable for planting buckwheat, chicory, alfalfa and other varieties .
3 intensive cultivation, timely sowing. Planting pasture, like growing crops, has a suitable sowing season. Except for grain pods, Sudan grass, Emperor bamboo grass, and Mexican corn for spring sowing, most forage grasses are suitable for autumn sowing. Forage seeds generally have small seeds, and they must be intensively ploughed before sowing, and sufficient base fertilizer should be applied to facilitate rapid and uniform seed emergence.
4. Strengthen management and promote its growth. The first is to break the surface of the table. After the pasture is sown and before emergence, the surface of the soil tends to form a compaction, which affects the sprouting and must be removed in time. The second is to remove field weeds. According to the actual situation of pasture varieties and area, choose the appropriate herbicide. Third, reasonable irrigation and fertilization, adequate water and fertilizer are the key measures to give full play to the potential of high quality forage grass production. Under normal circumstances, high-quality forage grass and dampness are afraid of flooding, and irrigation and drainage must be performed in time. The number of irrigations and the amount of irrigation vary depending on the type of grass and irrigation conditions. The basic fertilizer should be applied before planting, and the basic fertilizer should be based on basal fertilizer. The seed fertilizer should be applied to the seed fertilizer at the same time. The amount of seed fertilizer should be small. Inorganic phosphorus and nitrogen fertilizer should be used as the main fertilizer. Fertilizer should be topdressing after seedling emergence. Topdressing fertilizer is generally based on fast-acting inorganic fertilizer. The first topdressing should be carried out before the start of growth until delivery, with nitrogen as the main fertilizer, followed by phosphate fertilizer to increase the tillage of the pasture. The second topdressing should be applied before the harvest, potassium, nitrogen fertilizer, without applying phosphate fertilizer. Summer fertilization is carried out after the first use. N, P, and K fertilizers are applied to promote the regeneration of forage grasses. In the autumn fertilization, adequate potassium and phosphate fertilizers can be applied without the need of applying nitrogen fertilizer to ensure the need for hibernation and regeneration of pastures.
5. Timely cutting, effective use. The time of pasture cutting is generally determined according to the feeding target and needs, but the growth of pasture itself must also be considered. Castrate too early, low yield; late cutting, rough old grass, reduced nutrients, unfavorable regeneration: most leguminous pastures are mostly in the early flowering stage, grasses are grazing in the early earing stage, which can have higher yield At the same time, it is also rich in nutrition. Can not be castrated to keep the earthworms too low and the frequency of castration, leaving the earthworms too low will affect the growth of pasture, generally stay 10cm (King bamboo grass, hybrid Iris leaves 15cm). Over-frequency mowing can lead to the decline of pastures and grasslands. According to the purpose, the number of mowing should be used to control their quality and yield. If the grass is tender and the amount of leaves is large, the number of cuttings will be increased; if silage is used, it needs to be more. With high yields, the number of cuts is reduced, and even when silage is cast only once.
6. Raising grass and livestock to improve efficiency. Farmers must determine the species and area planted for pasture based on the number of livestock and poultry raised. Under normal circumstances, planting one hectare of annual ryegrass can produce 7.5-15 million kilograms of fresh grass, raising geese and rabbits 1200-1800, raising 150-225 sheep, and 15 sheep.
Cauliflower (Brassicaoleraceavar.botrytis) is an annual or biennial herb of the cruciferous family, and the edible part is its stem and leaves, also known as cauliflower, lotus cabbage, broccoli, watercress, and broccoli (green). There are two kinds of cauliflower, white and green. The green one is also called broccoli and broccoli. The hometown of cauliflower is in Western Europe. The origin originates from the Mediterranean coast of Europe. It was introduced to my country in the middle of the Qing Dynasty. It was popularized and popularized after 1949 and became a popular vegetable. Now it is cultivated all over the country. Cauliflower is one of the ingredients with the most flavonoids. In addition to preventing infections, flavonoids are also the best blood vessel clearing agents. Regular consumption can reduce the risk of heart disease and stroke. Cauliflower has a reputation in Europe as "a godsend medicine" and "the poor man's doctor".
