Integrated cultivation method for wheat and corn

Abstract

The invention provides an integrated cultivation method for wheat and corn. The integrated cultivation method comprises the steps of seed selection, land preparation, sowing and fertilization. The wheat is uniformly sowed in a ridgeless way at the sowing width of 45cm, the equal row interval of 25cm is adopted for sowing between the sowing widths of the wheat, wherein the corn seeds are sowed in the row interval of 25cm and are sowed by using the seeding method of single-seed strip cropping or alternate sowing of single and double seeds in each hole, and the equal row distance of 70cm is used. In the wheat sowing method, the current arable area is fully utilized, the strip cropping is changed into uniform ridgeless sowing, the sowing quantity is increased, the spike number per acreage is improved, the wheat growth space is fully utilized, the former intensive growth is changed into dispersed growth, the grain number per spike and grain weight are increased and the yield per unit area is improved. The corn is planted by using the optimal sowing method in international and domestic regions, where the row distance is expanded, the plant distance is reduced, the density is increased and the natural resources of light, gas and heat are fully utilized to improve the yield.

Description

technical field [0001] The invention relates to an integrated cultivation method of wheat and corn. Background technique [0002] Food is an important commodity related to the national economy and people's livelihood, and the foundation of economic development, social stability and national self-reliance. Ensuring national food security is always the top priority in governing the country. At present, there is a shortage of food in the world, and increasing food production has become a focus topic of common concern to all mankind. The increase in population, the reduction of land, the acceleration of urbanization and industrialization, the constraints of water and soil resources, and climate make it more difficult to increase food production continuously. How to use the existing It has become the general trend of the future development of agriculture to have land resources to greatly increase the yield per unit area! [0003] At present, the output levels of winter wheat and...

Problems solved by technology

The reform of planting methods can greatly increase the yield without increasing investment. At present, there is no standardized planting mode in winter wheat planting areas in my country

[0005] 2. There are the following reasons for the impact of corn production: first, the density is not enough, generally 3500-4500 plants, and the existing soil fertility and climatic conditions cannot be fully utilized; second, the extensive planting form of management is unreasonable; third, fertilizer application is unreasonable, and high-yield fields are insufficiently fertilized The ratio of nitrogen, phosphorus and potassium is unreasonable, there are many types of fertilizers, and the utilization rate of fertilizers is low.

The natural conditions of domestic summer corn, seeds, climate, and soil fertility meet the conditions of 900-950 kg. The current planting mode does not make full use of natural resources, and there is no complete cultivation mode

[0006] 3. The traditional planting methods of wheat and corn have many varieties, messy and miscellaneous, and there are few compact and dense-resistant types. It is difficult to exert the potential of wheat and corn to increase production, and cannot make full use of the light, gas and heat resources of wheat and corn.

Wheat and corn planting machinery is old and aging, resulting in unreasonable wheat row spacing and difficulty in increasing the density, causing corn to be planted on the last stubble of wheat. The phenomenon of lack of seedlings and ridges is serious, and the traditional planting mode is cumbersome and difficult to increase productivity.
