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

Example Embodiment

[0048] Example 1

[0049] (1) When the spring planting season comes, do not irrigate the land and keep the soil dry; plow the land to loosen and raked before planting, so that the soil is deep and finely broken, the soil is finely moistened, and the residual crops and stones are completely removed ;

[0050] (2) Ditching and trimming, so that the ditch is straight and flat, and the width of the border is 80 cm; a seeding ditch is opened along the extension direction of the border at 10 cm on both sides of the border, and the distance between the seeding ditch and the edge of the border is 10 cm , Apply 40 kilograms of nitrogen and phosphorus compound fertilizer per mu in the sowing ditch, and sow at medium intervals in the sowing ditch, with 2-3 seeds per hole, with a depth of 3 cm;

[0051] (3) After sowing, cover the border with a low-pressure high-density polyethylene colorless transparent film mulch with a width of 100 cm and a thickness of 0.005 mm. Cover with the plant. The mu...

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...
