Problems solved by technology

However, it is currently difficult to return straw to the field, and basically all of them are removed from the farmland or burned in the field, resulting in waste of resources and pollution to the environment.
The main problem of straw leaving the field is the decline of soil fertility. According to data reports, the soil organic matter drops by more than 0.01% every year; the second is serious soil erosion, mainly showing soil erosion (wind erosion and water erosion); ), the bottom of the plow is thick and hard, and it is difficult to maintain high yield and high efficiency

Embodiment 1

[0033] Location: Positioning test field in Gongzhuling Campus, Jilin Academy of Agricultural Sciences.

[0034] In the experiment, corn stalks were crushed and mixed, returned to the field with mulching, and straws were removed from the field. Except for the different methods of straw treatment and crushed and mixed sowing, the rest of the operations were exactly the same.

[0035] according to figure 1 The method shown is to carry out the crushing and mixing of corn stalks and return them to the field;

[0036] Straw covering and returning to the field: After the corn stalks are crushed, all the corn stalks are returned to the surface of the field;

[0037] Straw removal treatment: Remove all corn stalks from the corn field.

[0038] Test results: The treatment of crushed and mixed corn stalks can improve the water and heat conditions of the seeds. The ground temperature at 5cm is 0.6℃ higher, the soil moisture content is 2-5% higher, and the germination is fast, and the se...

Embodiment 2

[0041] Location: Positioning test field in Gongzhuling Campus, Jilin Academy of Agricultural Sciences.

[0042] The same treatment as in Example 1 was set up for corn stalks crushing and returning to the field, straw mulching and returning to the field, and straw leaving the field.

[0043] The test results are shown in Table 1. (1) For the growth height of corn in different ways of returning to the field, the straw crushing returning to the field is the best, followed by the straw leaving the field, and the straw mulching returning to the field is the lowest. This result is consistent with the trend of seedling survey results.

Embodiment 3

[0048] Location: Experimental Station of Xiangshan Village, Fanjiatun, Gongzhuling City, Jilin Province

[0049] The same treatment as in Example 1 was set up for corn stalks crushing and returning to the field, straw mulching and returning to the field, and straw leaving the field.

[0050]Test results: Straw mulched and returned to the field, the plant height is 206cm, the earing part is very low, only 79cm, the yield is not high, and the yield per hectare is 8969kg; the straw is mixed and returned to the field, the plant height is normal, 223cm, and the earing part is normal, 115cm , the highest yield was 9965.5kg per hectare, which was the highest compared with the other two treatments; the yield of straw mulching was lower, the yield per hectare was 8820.1kg, and the yield of straw leaving the field was 9356.6kg.

Abstract

The invention provides a corn tillage and cultivation method for northeast China, and relates to the technical field of crop cultivation. According to the method, through straw full-amount returning,a wide-width crushing and mixing technology is adopted, soil organic materials are added, the soil organic matter content is increased, soil is fertilized, the tilling property of soil is improved, the black land is scientifically and reasonably utilized, and the black land is protected. The scientific and technological means and technology are applied, starting from improvement of the agricultural resource environment, the problem about black land protection is solved, the black land quality is improved, the land production capacity is improved, agricultural resources are sustainably utilized, the virtuous circle of planting industry production is achieved, and the agriculture of the black land of northeast China is promoted to be developed to the direction of sustainability and high efficiency. Corn wide-narrow row convention planting is adopted, and the problems that during spring sowing, the soil water content is low, the soil moisture content is poor, and the seedling protection rate is low are mainly solved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for cultivating corn in Northeast China. Background technique [0002] Corn planting areas in the Northeast Plain of my country are rich in straw resources. However, it is currently difficult to return the straw to the field, and almost all of it is removed from the farmland or burned in the field, resulting in waste of resources and pollution to the environment. The main problem of straw leaving the field is the decline of soil fertility. According to data reports, the soil organic matter drops by more than 0.01% every year; the second is serious soil erosion, mainly showing soil erosion (wind erosion and water erosion); ), the bottom layer of the plow is thick and hard, and it is difficult to sustain high yield and high efficiency. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a kind of c...
