Precipitation weather occurred in most parts of Inner Mongolia in mid-July, especially in the northeastern region, which was conducive to the growth of pasture. Due to low precipitation and poor pasture growth, the pastoral areas in the central and western pastoral areas are particularly poor. In particular, the pastures in the west of Xilin Gol League and Baiqi, Siziwangqi and Damaoqi are extremely poor. In these areas, the pastures are already yellow, and the livestock are not full and need to be supplemented. In recent years, the drought in spring and summer has been more serious. Judging from the height map of pasture in mid-July, there is currently no grassing condition in these places. After the rain in mid-July, there was another high-temperature and dry weather with continuous rain in the central and western regions, which was very unfavorable for grassland vegetation growth.
The farmer said: "Futiancao, winter treasure, full nutrition, good taste", which means that only timely harvesting of pasture can improve the nutrients of pasture. The autumn (yellow) grass has a low nutritional value. The forages fed by winter animals are only full and cannot be full, resulting in the so-called "winter, lack of spring" and even death. In order to maximize the preservation of the nutrients in the forage, the optimum grassing period is the flowering period of the main pasture in the grass group, because the grass in this period is not only high in nutrient content, but also high in grass yield, and the utilization efficiency of pasture. Feeding effects are the best. The grassland in Inner Mongolia is generally concentrated in Hulunbeier City and Xilin Gol League. The average growth characteristics of grassland pastures in these two years, as well as the average annual growth height and the average flowering period of several main forage species, are as follows. forecast.
Drafting forecast results
According to the current pasture growth and weather conditions, the pastures in the main grassland areas in the central and eastern regions are better growing, and the flowering period of the pastures will be extended. The grassing period should start from the flowering period of most pastures. In mid-July, the heights of the pastures of Hulunbeier City, Xing'an League, Tongliao City, the west and south of Chifeng City, the eastern part of Xilin Gol League, Wulanchabu City Chayouqian Banner and Wuzheng Call are higher than 30cm and the maximum height is above 50 cm. These areas can catch the fine weather to fight grass; the height of the forage in the central and western parts of Xilin Gol League, the central part of Chifeng City, and the western part of Hulunbeier City is 15~30cm, and it is only necessary to play grass in early August.
Production Proposal
The grass season is in the rainy season, the grass has high water content, and the hay is prepared to prevent mold and rot. At present, there are many thunderstorms in Inner Mongolia, which brings certain difficulties to the grass-planting work. All localities should adjust the grass-scissing period in time according to the local weather conditions. The areas where grass has been implemented should be bundled in time.
