Problems solved by technology

[0005] Although China's corn silage silage has a long history in animal husbandry, long-term uni-sow planting has led to a decline in the ability to resist pests and diseases within the group, a decrease in yield, unbalanced nutrition, high acidity, and reduced feeding quality. During production, it is necessary to add urea to supplement the deficiency of non-protein nitrogen content, so it is difficult to ensure the quality of feeding, resulting in a decline in the quality of livestock products

Abstract

A silage corn and fodder soybean mixture sowing method includes firstly, preparing farmlands which are few in weeds and easy to realize mechanical operation; secondly, sowing at the beginning and the middle of May according to the parameters of 30-37.5kg / hm<2> of silage corns and 48-60kg / hm<2> of fodder soybeans, by the detail steps of preparing the farmlands in the autumn, removing weeds by means of rotary tillage and applying organic fertilizer, flatting and ridging with the row space of 70cm, and then sowing in drill by a precision dibbler for mixture sowing, sowing the two kinds of seeds along different lines in different holes; thirdly, performing field management by detail steps of turning up the farmland and weeding in the seedling stage, eliminating tall weeds manually without chemical herbicides, and then intertilling 1-2 times in the jointing stage, and applying urea fertilizer; and fourthly, harvesting green grass mixedly in the wax ripening stage of the silage corns. The silage corn and fodder soybean mixture sowing method has significant yield increasing effect as compared with that of the clean culture method; yield of the stem leaves of the fodder soybeans is increased after the mixture sowing; and nitrogen elements are continuously supplied to the silage corns in the growing period by rhizobia of the fodder soybeans through nitrogen fixation, and effect of promoting yield increasing mutually is achieved.

Description

technical field [0001] The invention relates to a technology for mixing silage feed raw materials, mainly a method for mixing silage corn and fodder beans. technical background [0002] my country is not only a large traditional agricultural country, but also a large animal husbandry country. However, due to the national conditions of a large population and little land, the shortage of feed and grain has always been a key problem that plagues the development of animal husbandry in our country. Heilongjiang Province is an important milk source base in the country. There are more than 2 million dairy cows in stock. In addition to the Wandashan Group in this province, dairy groups such as Nestlé, Guangming, Mengniu, and Yili have successively settled in Heilongjiang Province. With the implementation of the 10 million tons of milk project in Heilongjiang Province, a large amount of low-cost, high-yield, high-quality forage grass and fodder supply is required. Silage corn is an ...
