Select the optimal model to find "best partner" Guizhou Nannan carried out the soybean corn band -shaped composite and efficient planting suitable for regional characteristics

On July 12, the test demonstration base of the grain and oil crops of the Academy of Agricultural Sciences in Guiding Panjiang Town, in the fields of soybean corn band -shaped seeding, the straight lines were neatly planned.

As the scorching sun, the technician Zhao Zubin still inspected the field as usual. "The sun is too large, and the corn leaves are rolled up. Workers are arranged in the evening." Zhao Zubin said that from the current growth of the field, the "2+3" and "2+4" model is better. Good lighting, the Qian Dou 12, Guizhou Bean No. 10 and Corn in Soybean 988 and New Zhongyu 801 are better. These two corn varieties are compact types. Do not cover the light of soybeans, good ventilation, which is conducive to soybean pollination pods. Of course, now it is only the situation of field observation, and finally it depends on the data of the production and acceptance. "

"The density of this group of corn is too large, nutrition cannot keep up, the stems are thin, and the roots are not enough. If the wind is large in the later period, it may fall down, and it will also affect the growth of soybeans. It is better. The corn variety is compact. When planting, the lighting design and the spacing of the plant are more reasonable. The two varieties interfere with each other. "Zhao Zubin observed while commenting.

Soy corn band -shaped composite efficient planting technology test is the unveiling project of Qiannan Prefecture Academy of Agricultural Sciences. It mainly carries out the research on soybean corn band -shaped composite planting technology and full -process mechanized application research to conduct different varieties combinations, different density, different spacing mode and weight loss comparison. The test summarizes the soybean corn band -shaped composite planting high -yield cultivation technology that is most suitable for the geographical climate characteristics of Qiannan region, so that the benefits of soybean corn band -shaped composite planting are maximized.

The three -dimensional climate characteristics of Qiannan are obvious. Whether the species spacing, plant spacing and varieties formulated in the technical solution are suitable for Chiannan planting. It is necessary to speak with data. Program.

"2+3" mode of soy corn band composite efficient planting technology test

It is understood that in the Soyan and Cornblades composite planting technology test, the Qiannan State Academy of Agricultural Sciences selects 12 corn varieties and 7 soybean varieties for combination to carry out "1+1", "2+2", "2+3", "" 2+4 "4" density and 4 -spacing mode cultivation tests. Through comparison, the optimized variety combination, the most suitable cultivation density, intermediate set mode, and the most accurate fertilization amount.
