Problems solved by technology

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

Embodiment 1

[0032] In 2020, the experimental research on compound planting of trailing forage soybean (Fenmu Green No. 9) and silage corn (Ningyu 53) will be carried out in the experimental base of the Institute of Crops, Ningxia Academy of Agriculture and Forestry. Species as a control (planting area of ​​240 square meters).

[0033] The method for improving the quality of silage corn feed based on trailing forage soybeans of the present embodiment is as follows:

[0034] S1, soil preparation and fertilization: in the autumn of the previous year, the land was deeply plowed by 20cm, filled with winter water, and the soil was prepared by mechanical rotary tillage before sowing in spring, and basal fertilizer was applied; the basal fertilizer was 15kg / mu of urea, 15kg / mu of diammonium phosphate and compound fertilizer 35kg / mu; N, P in the compound fertilizer 2 O 5 , K 2 The mass fraction of O is 16%;

Abstract

The invention provides a method for improving the quality of silage corn feed based on trailing forage soybeans. The method comprises the following steps: soil preparation and fertilization, selection of high-quality varieties, seed treatment, and 50% acetochlor milk soil spray treatment before sowing; The method of hole-sowing or peer-separated seeding is to simultaneously sow, cultivate, and weed the trailing forage soybean and silage corn seeds, and irrigate the silage corn at the jointing and booting stage, the tasseling flowering stage and the grain-filling stage, and kill the heartworm, red spider, and corn borer at the early stage of occurrence. Insects, the silage corn kernels are in the middle and late stages of wax ripening, and the whole plant silage corn and the whole plant creeping forage soybean are harvested at the same time, and silage is obtained after harvesting to obtain silage. The invention utilizes the habit of growing upwards in the vines of the trailing forage soybeans, and the trailing forage soybeans and the high-stalk crops silage corn are compounded, and the whole plant of the two is mixed to harvest the silage at the wax maturity stage of the corn grains, thereby increasing the yield and coarseness of the silage corn feed. The protein content makes up for the shortcomings of low content and poor quality of single silage corn protein.

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 trailing forage soybeans. Background technique [0002] At present, the number of cattle, sheep and other major livestock in my country is about 180 million heads. They are fed according to standardized diets. The minimum demand for silage is about 740 million tons, while the current production of silage is only about 290 million tons. The gap is relatively large. If we further consider 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 plant of silage corn is only 6% to 7%, which is far from meeting the demand of ruminants for vegetable protein, and additional soybean meal needs to be added to supplement the protein content in the feed. The raw material for...
