CCTV news: Walking into the Central Plains large granary Henan, look at the first year of large-scale demonstration and promotion of corn and soybean compound planting, the new planting mode is matched with new agricultural machinery and equipment, bringing new changes here.
Soybean corn interplanting ushered in a concentrated harvest season
Wang Yidan, reporter of the main station: This is a soybean and corn ribbon compound planting field in Xinzhengxindian Town, Henan. Behind me were rows of corn and soybeans out of sight, and four harvesters were busy harvesting. In the field behind me, although the density of corn planting is relatively high, the distance between one corn plant is relatively narrow, according to our planting specifications of 8-12 cm, but the size of the corn on the cob is not affected, we peel it and see, the corn grains in it are also relatively full, the arrangement is also very neat, there is no lack of grains. There are also a lot of pods on a soybean stick, and the pods are also full.
If corn yields are not reduced, one more season of beans will be harvested, and the income will increase by 600 yuan per mu
This compound planting mode is to increase the corn planting row spacing, reduce the plant spacing, make room without reducing the amount of corn planting, and plant soybeans between the corns. This planting mode can be said to make full use of the edge advantage of corn, the so-called side advantage is that in a corn field, the closer to the corn on the side, the better the light and wind permeability, and the larger the cob. In this nesting mode, almost every row of corn can enjoy this edge row advantage. At the same time, soybean rhizobia has the functions of nitrogen fixation and fertilization, which has a positive effect on the fertility of the land and can provide nutrients for the growth of maize. As far as this land is concerned, this year's yield is 530 kilograms of corn per mu of land, which is equivalent to the yield of ordinary corn land, and at the same time, it will harvest 101 kilograms more soybeans, a net increase of 600 yuan per mu of land at market prices.
