Method for improving quality of silage corn feed based on vine forage soybeans

Abstract

The invention provides a method for improving the quality of silage corn feed based on vine forage grass soybeans. The method for improving the quality of the silage corn feed based on the vine forage grass soybeans comprises the following steps of preparing soil and applying fertilizer, selecting high-quality varieties, treating seeds, spraying 50% acetochlor emulsion soil before sowing, simultaneously sowing the vine forage grass soybeans and silage corn seeds, intertilling and weeding in a side hole sowing mode or a mode of sowing in the same row at intervals, irrigating in a jointing booting stage, a tasseling and flowering stage and a filling stage of silage corn, killing insects in the initial stage of budworms, red spiders and corn borers, simultaneously harvesting the whole silage corn and the whole vine forage grass soybeans in the middle and later stage of wax ripening of silage corn kernels, and ensiling after harvesting to obtain silage. According to the method for improving the quality of the silage corn feed based on the vine forage grass soybeans, the vine forage grass soybeans and the long-stalked crop silage corn are compositely planted by utilizing the habit of vine winding upward growth of the vine forage grass soybeans, and the whole plants of the vine forage grass soybeans and the long-stalked crop silage corn are mixed to harvest the silage in the dough stage of the corn kernels, so that the yield and crude protein content of the silage corn feed are increased, and the defects of low protein content and poor quality of single silage corn are overcome.

Description

technical field [0001] The invention belongs to the technical field of silage corn feed, and in particular relates to a method for improving the quality of silage corn feed based on creeping forage soybeans. Background technique [0002] At present, the number of major domestic animals such as cattle and sheep in my country is about 180 million, and they are fed according to standardized rations. The minimum demand for silage is about 740 million tons, while the current production of silage is only about 290 million tons, and the gap is relatively large. Large; if further considered from the perspective of high-quality feeding, the silage gap rate reaches 83%. [0003] Silage corn is one of the important sources of silage. However, the crude protein content of the whole silage corn plant is only 6% to 7%, which is far from meeting the needs of ruminants for plant protein, and additional soybean meal is needed to supplement the protein content in the feed. The raw material f...
