Problems solved by technology

[0004] In order to solve the problems existing in the existing seed-cleaning cultivation technology: due to the tall plants and flat plant types, the four sides are closed, the group has poor ventilation and light transmission, and the photosynthetic effect of the middle and lower leaves of the plants is weakened, which is not conducive to the growth of the crops. The present invention provides a A high-yield crop rotation cultivation method with strong operability, high seedling rate in the field, good photosynthetic effect, and complementary fertilizer efficiency among crops, that is, a high-yield rotation cultivation method for short-stalk early-maturing sorghum and late-maturing corn or dwarf-stalk early-maturing soybean and late-maturing corn

Embodiment 1

[0064] Example 1 Cultivation Test of Late Maize / Dwarf Early Maturity Sorghum High Light Efficiency Rotation

[0065] According to the annual test plan and the market demand for red sorghum, this test is specially designed to improve the photosynthetic effect, rationally rotate crops, and create the best output value per unit area.

[0066] A kind of late-maturing corn / dwarf-stalked early-maturing sorghum high light-efficiency crop rotation cultivation method of the present invention is specifically realized through the following steps:

[0067] Step 1. Site selection

[0068] The test time is 2014; the test location: the experimental contracted field of Binhe Town, Nong'an County, Jilin Province; the area of ​​the experimental field is 100 square meters; the previous work of the experimental field: the annual yield of corn in this field is 10,000 kg per hectare.

[0069] Step 2: Soil preparation and fertilization

[0070] After autumn, deep rotation stubble removal and ridgi...

Abstract

The invention discloses a high-yield crop rotation cropping method, and relates to the field of agricultural planting. By means of within-year intercropping, next-year alternate husbandry and over-year rotation, late maize and short-stalked early-maturing sorghum (soybeans) are selected for intercropping, and ridge ratio is 2:2, 1:3, 3:3 or 2:3. Suppression and moisture conservation are performedafter sowing, double-effect herbicides for sealing are sprayed after maize sowing and before emergence, field seedlings are complete and uniform as required, weeds are eliminated, inter-tillage is performed when maize seedlings grow to achieve 7-8 leaves, nitrogen fertilizers are applied between lines of the maize and the sorghum, and insecticides are sprayed at the end of May to July to prevent corn armyworms and sorghum aphids. Dichlorvos are sprayed in the middle ten days of August to prevent soybean pod borers, and water supply is ensured in soybean flowering, podding and seed filling periods. When maize plants grow to an 8-leaf period and before tasseling, leaf fertilizers and special maize regulators yu-huang-jin are sprayed to perform chemical control and treatment. The high-yield crop rotation cropping method is strong in operability, high in field emergence percentage, good in photosynthetic effect and complementary in intercrop fertilizer efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a high-yield crop rotation cultivation method. Background technique [0002] In agricultural production, cultivation methods such as crop intercropping, interplanting, belting, and clearing are widely used. It is the main cultivation measure for agricultural production. The above-mentioned cultivation techniques played an important role in agricultural production in the past, however, along with the continuous innovation and development of crop breeding techniques, they also showed shortcomings. For example, in clear-seeding cultivation techniques, due to the tall plants and flat plant types of crops, the field canopy is closed, the ventilation and light transmission of the group is poor, and the photosynthetic effect of the middle and lower leaves of the plants is weakened, which is not conducive to crop growth; the ordinary intercropping cultivation technique is ...
