Method for corn-soybean strip type interplanting

Abstract

The invention relates to the technical field of agricultural cultivation, and discloses a method for corn-soybean strip type interplanting. With the adoption of the method, corns and soybeans are planted alternately in a strip type. When corn grain milk lines reach 1/2 to 3/4, a stalk and leaves above three leaves of an ear are removed, the three leaves of the ear are reserved, and all leaves below the three leaves of the ear are sheared off adopting a leaf ring as a basic standard. According to the invention, the leaves below the three leaves of the ear, and the stalk and the leaves above the three leaves of the ear are removed timely and suitably, the original source library relationship of corn plants is broken, the transport direction of organics is changed, a new source library relationship is established, a carbon pool effect of source leaves is enhanced, nutrition provided for grains is improved, simultaneously, the growing environment of the soybeans in a strip type interplanting mode is improved, and the corns and soybeans have high yield at the same time.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for corn-soybean strip interplanting. Background technique [0002] Corn is the second largest grain crop in my country and the grain crop with the highest total output in the world. Maize has a large planting area and a wide distribution in China. It is the crop with the largest area and yield potential among dryland grain crops, and it is also one of the main grains for people in northern and southwestern mountainous areas of China. In addition to food, corn is also widely used in the fields of feed and industrial raw materials, such as the production of livestock feed, papermaking, brewing of shochu, and production of industrial alcohol. Because corn has outstanding advantages in many aspects, its demand is increasing, and it is one of the important crops in our country. Similarly, soybean is also an important crop in my country. It integrates food cro...

Problems solved by technology

[0004] However, in the current corn-soybean strip interplanting method, the mutual shading between the redundant leaves in the middle and late stages of corn filling not only causes field shading and poor light conditions, but also a large number of redundant leaves will excessively consume corn kernels. The transported energy and photosynthetic products are not conducive to the filling of corn kernels, resulting in a decrease in corn kernel weight and affecting the final yield of corn

At the same time, the dwarf crop soybean in the symbiotic period will be at a disadvantage in light energy interception, resulting in thin and thin seedlings, easy lodging, and reduced photosynthetic function, which is not conducive to the growth of soybeans and affects the final yield of soybeans

[0005] The existence of the above-mentioned production problems has prevented the strip interplanting method of corn and soybean from achieving high yields of the two crops at the same time, and even caused a sharp decline in crop yields, failing to take advantage of the efficient use of resources in the strip interplanting mode
