specific Embodiment approach 1

[0009] Specific embodiment one: the mixed planting method of lentils and silage corn in this embodiment includes site preparation, application of base fertilizer, sowing, replanting, transplanting, intertillage weeding, top dressing, pest control and harvesting; lentils and silage corn seeds are sown simultaneously or in stages Sowing; silage corn seeds are sown in the soil completely thawed, the soil temperature of the 5-10cm plow layer in the farmland is 6-10℃, the sowing depth is 5-6cm, the ridge distance is 65cm, and the hole distance is 25-30cm; lentil and silage corn seeds Planted in the same hole; the variety of lentils is Longyin Lentil No. 1.

[0010] The fresh biomass yield of single planting silage corn is 60-70 tons / ha, and it is difficult to increase the yield per unit area by means of existing technologies; and the fresh biomass yield reaches more than 75 tons / ha by using the present embodiment.

specific Embodiment approach 2

[0011] Specific embodiment two: the difference between this embodiment and specific embodiment one is: lentils and silage corn seeds are planted in stages: the emergence rate of silage corn is 80% sowing lentil seeds, and 2 grains of lentil seeds are sown in every hole. Other steps and parameters are the same as those in Embodiment 1.

[0012] The present embodiment has a high seedling preservation rate and a large yield increase range.

specific Embodiment approach 3

[0013] Specific embodiment three: the difference between this embodiment and specific embodiment one is: the grain number ratio of lentils and silage corn seeds in the same hole is 1~2:2~3. Other steps and parameters are the same as those in Embodiment 1.

Abstract

The invention relates to a method for planting hyacinth beans and silage corns in a mixed manner, in particular to a method for planting hyacinth beans and silage corns. The method solves the problems that the present silage corn feed contains low content of protein, and the economic cost is high for adding extra protein feed. The method comprises the following steps of preparing land, applying subsoil, sowing, replanting, transplanting, intertilling, weeding, topdressing, preventing and controlling diseases and insect pest and reaping. The seeds of the hyacinth beans and the silage corns aresowed in the identical hole, and the variety of the hyacinth beans adopts No.1 Longyin hyacinth beans. By adopting the method, the hyacinth beans with high protein content and the silage corns are planted in a mixed way, therefore, not only the output of the fresh biomass is improved by more than 10 percent, and the protein content of dry basis of the silage is improved by 2 to 2.5 percent. Because the hyacinth beans and the silage corns for are planted in a mixed way, the content of the crude protein in the silage is increased, the nutritious component of the silage is improved, and the economic cost of the feed is also reduced.

Description

technical field [0001] The invention relates to a planting method of lentils and silage corn. Background technique [0002] Silage corn is the main silage for dairy cows and other livestock. Due to the low protein content of silage corn, which only accounts for 7% to 10% of the dry weight of silage corn, it cannot meet the protein demand of dairy cows and other livestock. At present, additional protein feed is used to make up for the lack of crude protein content of silage corn feed, but this method has the problem of high production cost. Contents of the invention [0003] The purpose of the present invention is to solve the problem of low protein content of current silage corn feed and high economic cost of additional protein feed, and to provide a method for mixing lentils and silage corn. [0004] The mixed planting method of lentils and silage corn includes site preparation, application of base fertilizer, sowing, replanting, transplanting, intertillage weeding, top ...
