Problems solved by technology

However, due to its complex heredity and rich variety of variations, there are shortcomings in the conventional breeding process, such as too long cycle, too large coefficient of variation, and affecting the growth and development of offspring. Modern biological breeding technology not only overcomes the above-mentioned shortcomings and deficiencies, It also improves breeding speed and quality
[0003] During the entire growth process of crops, weed damage has always been a key issue affecting crop yield. If weeds are not removed in time, they will compete with growing crops for fertilizer and water, which will affect crop growth and reduce yield. , and if weeds are removed, it will take a lot of manpower and increase the cost. If herbicides are used to remove weeds, it will also affect the crops and cause environmental pollution, which is not conducive to environmental protection
Especially in some arid areas, weeds compete with crops for water seriously, and the cost of irrigation is high, so it is urgent to solve the problem of weeds

Abstract

The invention provides a corn cultivating method by using mulching films, and belongs to the technical field of planting. The corn cultivating method includes that a cultivation land is not watered before sowing, so that weed seeds in soil can be dried to death, and after sowing and the cultivation land is covered with the mulching films, the land is watered again, in this way, moisture can be controlled to permeate into seed positions only but cannot permeate further, water supplying to weed portions inside furrows is avoided, growth of weeds is restrained, and furtherly by restraining of the mulching films, growth of the weeds is completely eradicated. By means of sowing prior to watering, the problem of weed in the cultivation land is solved successfully, environment-friendliness is realized due to no use of farm chemical, corn yield is increased, and the amount of water is decreased. Compared with a traditional cultivating method, the corn cultivating method by using the mulching films has the advantages that the corn yield is increased by 15%, the amount of watering is decreased by 30%, and the growing weeds are reduced by more than 85%.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a film-mulching method for corn. Background technique [0002] Corn is an annual herbaceous plant of the grass family Zea genus. Alias: maize, stick, corn, rice, millet, corn, corn, pearl rice, bract reed, big milo. Maize is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop. It is also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. Corn has always been known as a longevity food, rich in protein, fat, vitamins, trace elements, cellulose, etc., and has great potential for developing high-nutrition, high-biological function foods. However, due to its complex heredity and rich variety of variations, there are shortcomings in the conventional breeding process, such as too long cycle, too large coefficient of variation, and affecting the...
