Xincheng county cattle and sheep forage status quo

1. Feed material composition

At present, the forage grass sources in this county are mainly composed of corn straws, sugarcane leaf tails, forage mulberries and grassiness. The corn straw and the sugarcane leaf tail are rich in resources, the elephant grass type yield is high, and the elephant grass type yield is a main forage grass resource for cattle and sheep (Table 2).

TABLE 2 comparative analysis of straw Nutrition composition (air drying base)

2. Forage yield and straw utilization condition

Rice resource: the planting area of rice in county is 18 ten thousand mu, most of the rice is planted in small plots of households, and rice straw is produced 9 ten thousand tons each year. The straw resources can not be utilized at present due to the lagging of the harvesting equipment.

Mulberry resource: the mulberry resources in counties are mainly used for picking leaves and breeding silkworms, the variety is 'Lun educing 40', the planting area is 26 ten thousand mu, and 20.8 ten thousand tons of straws are planted in annual mulberry. After each leaf picking, although the residual mulberry leaves and mulberry branches exist, the mechanical harvesting cannot be applied for planting planning reasons, and the existing domestic equipment for crushing the mulberry branches into feed falls behind, so that the effect is not good. Moreover, the cost of manual collection is high, so that the mulberry leaf and mulberry twig resources cannot be utilized.

Corn straw and sugarcane tail tip resources: the planting area of the corn in the whole county is 16 ten thousand mu, and 4.8 ten thousand tons of corn straws can be produced each year. The planting area of the sugarcane is 8 ten thousand mu, and 3.2 ten thousand tons of tail leaves of the sugarcane can be produced. The number of the machine-harvesting parts of the corn straws is small, but the machine-harvesting parts of the corn straws and the sugarcane tail tips are not large, the current manual collection cost is high, the efficiency is low, and the seasonality is obvious. And the mechanical processing technology of the corn straw and the sugarcane tail tip which cannot be mechanically harvested is not mature enough, and more uncontrollable factors exist, so that the corn straw and the sugarcane tail tip can be processed into a small amount of high-quality forage grass.

Forage grass resources: the existing pasture grass has the defects of small planting area, insufficient planning, insufficient scientific planting technology, low yield, no mechanical seed collection, low production efficiency and far distance from the localization and quality improvement of the forage grass in the county.

According to the statistics data of agricultural rural bureau in Xincheng county in 2018, the feed resources in the county are 82.6 ten thousand tons, the feed utilization rate is 4.5 ten thousand tons, and the utilization rate is only 5%.

Based on the fact that the forage grass has high biological yield and can be harvested in four seasons, the forage grass planting is mainly used as a forage grass guarantee for breeding beef cattle and mutton sheep in the county all the year round, straw feed resources such as corn straws and sugarcane leaf tails are fully utilized in seasons, and the planting income of farmers is increased. And constructing a pasture and grass high-quality planting demonstration base. Coordinating local governments and breeding enterprises, organizing farmers to adjust land or organizing established land cooperative society, putting the land into stock, and implementing land leveling through government support (equivalent to forward agricultural planting subsidy) to achieve three-way leveling. The forage production enterprises are responsible for organizing and planting, professional technical teams follow technical guidance to carry out scientific and modern field management, fertilization and high-quality mechanical harvesting, the forage planting achieves high yield, high quality and high efficiency, existing land of farmers is put into stocks and fixed income, the forage cost of the breeding enterprises is reduced, and the economic benefit is obviously increased; the industry realizes the high-quality development of agricultural efficiency improvement, farmer income increase and financial income increase.

4. The processing technology of the innovative forage is improved, and the quality of the forage product is improved. The method has the advantages that the quality of feed products is improved by integrating a briquetting technology, a puffing technology, a microbial technology and the like, in the aspect of crop straw feed, a composite microbial inoculum with high activity and strong suitability is screened out, the processing technology is optimized, low-moisture briquetting silage and full-price pellet feed are popularized and applied in a county, the formula and the processing technology of daily ration of cattle and sheep are continuously improved, the conventional single silage of the first generation, the low-moisture mixing briquetting of the second generation and the full-price pellet feed of the third generation can be completely replaced by the traditional daily ration of 'forage + concentrated feed', the cattle and sheep are raised like pig raising chickens, the labor intensity and the cost are reduced, the industrial production of the cattle and sheep feed is realized, and a foundation is provided for the intelligent automatic precise feeding of the next step.

Thirdly, realizing the analysis of the localization and the optimization of the forage grass industry benefits

The localization and the optimization of forage grass need government support, enterprise responsibility, technical follow-up, farmer cooperation, multi-aspect effect, multi-win effect and obvious economic, social and ecological benefits. The localization and the optimization of forage are realized, the situation of win-win is reached by governments, farmers and enterprises (cultivation and planting), and the benefit analysis is detailed in the table 4.

Farmer (cooperative): in the form of land circulation or stock entry, land rent and bottom guarantee is 600 yuan/mu/year + yield is 10 yuan/ton, and income per mu of land per year is more than 750 yuan.

Government: the construction period is 5 years, the stable price of the high-quality forage is guaranteed within 5 years, the sustainable development of the industry is guaranteed, and the industrial development, the income increase of farmers and the financial increase of the capital are realized.
