Wheat-corn interplanting method

Abstract

The invention relates to the technical field of agricultural planting and discloses a wheat-corn interplanting method. According to the wheat-corn interplanting method, wheat planting belts and corn planting belts are arranged in a alternate mode, wheat is planted prior to corn and at 4 rows each belt, the interval between the second row and the third row of every belt is 25-35 cm, the interval between every other two neighboring rows is 20 cm, and unplanted rows 125-135 cm wide are reserved between every two neighboring wheat planting belt for planting the corn belts; corn is planted at 2 rows each belt, the interval between every two neighboring rows is 45 cm, and the interval between neighboring corn and wheat is 40-45 cm. The wheat-corn interplanting method reduces the number of planting rows of wheat, achieves different planting row widths and reduces corn planting interval by 5 cm, thereby increasing the interval between wheat and corn, optimizing the planting environment during interplanting period of wheat and corn, reducing the shading effects of wheat on corn and meanwhile improving the yield per unit or wheat and corn.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a wheat-corn intercropping planting method. Background technique [0002] The four southwestern provinces (cities) of my country, Sichuan, Guizhou, Yunnan, and Chongqing, have a lot of people and little land, with a large proportion of dry land in hills and mountainous areas, and a high degree of multiple cropping. They are typical dryland and multi-crop agricultural areas in southern my country. The so-called multiple cropping refers to the planting method of continuously planting two or more crops on the same field in one year, such as wheat-jade twice a year, wheat-cotton twice a year, wheat-rice-rice three times a year, etc. ; In addition, there are three crops in two years, five crops in three years, etc. After the last crop is harvested, in addition to directly sowing the next crop on the ground of the previous crop, regeneration, transplanting, intercropping...

Problems solved by technology

[0004] However, in the wheat-corn symbiotic period using the "double three 0" planting method, wheat has a strong shading effect on corn seedlings, and the quality of corn seedlings is not high, which seriously affects the unit yield of corn. At the same time, the five rows of wheat are all equal The row spacing and the middle row wheat growth are at a serious marginal disadvantage. The wheat growth varies greatly between different rows, the population quality is poor, and the middle row is prone to lodging in the later stage, so that the unit yield of wheat is not high. These two reasons make the yield per mu of the two crops not tall

If the width of wheat is reduced at will, the number of rows is reduced, the row spacing of wheat is expanded, or the number of rows of corn planting is increased, the planting environment of wheat and corn will not conform to the natural law and the growth characteristics of the crops, and finally lead to a decline in the yield per mu of the two crops

This planting method of sacrificing one crop while ensuring the yield of another crop limits the economic benefits of the two crops, making the yield per unit of crops under the traditional wheat-corn intercropping planting method not high, which ultimately leads to low yield per mu and does not exert its full potential. Advantages of efficient use of resources in intercropping planting mode

[0005] In addition, because the number of rows of wheat in the "double three 0" planting method is too close, the distance between the openers of the agricultural machinery relying on the "double three 0" planting method is also closely spaced, and the openers are easily covered by stubble and debris during sowing operations. Grass and large clods are clogged, and the machine has poor passability, resulting in uneven seeding, lack of seedlings and broken ridges, and many pimple seedlings; secondly, the width of wheat is too large, and the crown width is too wide in the later stage. When sowing corn, the mechanical operation It is inconvenient, and even small machinery cannot drive in; third, the distance between wheat and corn is too small, corn is in the jointing stage when wheat is harvested, and mechanized harvesting of wheat is easy to damage corn
