Problems solved by technology

If the traditional planting mode is adopted, the arable land cannot be effectively used, and the highest economic benefits cannot be achieved. Moreover, the land consumption during the growth of silage corn is very large, which greatly increases the amount of fertilizer used.
[0004] In addition, silage corn is mainly for the purpose of harvesting nutrients, which is different from the cultivation and harvesting methods of the existing grain-corn intercropping legumes, so only the existing cultivation methods of grain-corn intercropping legumes cannot meet the demand
In addition, the planting density of corn and leguminous plants also has a greater impact on it. If the density is small, the land utilization rate will not reach the highest level, making the economic benefit poor; The utilization efficiency of water, air, fertilizer and other factors will be affected, and it will easily lead to insect damage

Embodiment 1

[0025] The intercropping cultivation method of silage corn and green beans includes soil preparation, application of base fertilizer, sowing, equalization of seedlings, intertillage and weeding, top dressing and harvesting.

[0026] Soil preparation: The land is arranged as an intercropping cultivation method, that is, the cultivation method of green beans intertwined between rows of silage corn, and the sowing method is hole sowing, so the distance between rows of silage corn is set to 50cm, and each row is adjacent to each other. The distance between the two silage corn holes is set to 40cm, and the row spacing of green beans and silage corn interplanted between rows of silage corn is 8-15cm.

[0027] Apply base fertilizer: the base fertilizer of the present invention is applied in two ways. First, apply 300kg / hm 2 ~600kg / hm 2 of compound fertilizer; second, apply 22500 kg / hm 2 ~45000kg / hm 2 Decomposed farmyard manure. What applied in this embodiment is 400kg / hm 2 comp...

Embodiment 2

[0035] The difference between this embodiment and embodiment 1 is only: the applied base fertilizer is different from the top dressing, and the base fertilizer applied in this embodiment is 36000kg / hm 2 Farmyard manure after decomposing, the topdressing fertilizer is 75kg / hm 2 of urea. The difference of this embodiment is also that the density of healthy seedlings after uniform seedlings is about 62000 strains / hm 2 .

Embodiment 3

[0037] The difference between this embodiment and Example 1 is only: the base fertilizer applied is different from the top dressing, and the base fertilizer applied in this embodiment is 28000kg / hm 2 After decomposing farmyard manure, the topdressing fertilizer is 23000kg / hm 2 decomposed farmyard manure. The difference of this embodiment is also that the density of healthy seedlings after uniform seedlings is about 61000 strains / hm 2 .

[0038] After testing, the yield of fresh organisms harvested is 134.42 t / hm using the planting method of the above embodiment 1 2 , Compared with the harvest of silage corn in the prior art, it has increased by 85.54%, wherein the protein content has increased by 51.98%, and the digestibility has increased by 2.32%.

Abstract

The invention discloses a method for intercropping silage corn with kidney bean, which includes land preparation, base fertilizer application, seeding, seedling evening, intertillage for weeding, topdressing and harvesting. The method is characterized in that the kidney bean is intercropped among rows of the silage corn, the row spacing of the silage corn is 40-50cm, the spacing between one silage corn row and one kidney bean row is 8-15cm, and seeding depth is 3-5cm. The method has the advantages that land is effectively utilized, biological yield is increased, crop quality is improved, cost is saved and the like.

Description

technical field [0001] The invention relates to a cultivation method, in particular to a cultivation method of silage corn and kidney beans. Background technique [0002] Silage Corn ( Zea mays L.) is the most widely used silage in the world, and it is also one of the indispensable and important basic feeds for the breeding industry, especially the cattle breeding industry. However, the protein content of silage corn is generally low, generally accounting for 6%-9% of its dry matter, and contains more lignin, semi-lignin, cellulose compounds and other components that are difficult to be digested by animals, and the content of fermentable carbohydrates is low. , so that the overall nutritional level of the ruminant roughage supply system decreases. Kidney bean is an annual vine herb of the leguminous family with wide adaptability. It is widely cultivated especially in southern agricultural areas. It is one of the most common vegetables with high economic value. Kidney bean...
