Embodiment 1

[0028] Example 1 Detecting the shade tolerance and shade tolerance of soybeans in different growth periods

[0029] The experiment was carried out in the teaching and research park of Sichuan Agricultural University in Yucheng District, Ya'an City, Sichuan Province.

[0030] The spring corn variety was Chuandan 418, and the soybean variety was Gongxuan No. 1, Guixia No. 3, Qiandou No. 3, and improved 8157.

[0031] The spring corn was sown directly on April 3, and cultivated in alternate wide and narrow rows, with a row spacing of 1.55m in a wide row, a row spacing of 0.45m in a narrow row, and a hole spacing of 0.35m. Three seeds were sown in each hole, and one seedling was established in each hole when it grew to three leaves. On the day of corn sowing, sow a row of soybeans in the middle of the narrow row, with a hole distance of 0.3m, sow 4 to 6 seeds in each hole, and when the soybeans grow to the second node stage, set 3 seedlings in each hole. The length of each soybea...

Abstract

The invention relates to the technical field of agriculture and discloses a method for detecting shade tolerance of soybeans in the field. The method comprises the following steps: planting spring corns in spring in a field in a manner of wide/narrow row alternation; planting to-be-detected soybeans in the narrow row of the spring corns in spring; alternatively planting the soybeans and the spring corns, and as a reference, purely planting the to-be-detected soybeans in spring; after maturing and harvesting, respectively detecting the grain outputs of the alternatively planted to-be-detected soybeans in spring and the purely planted to-be-detected soybeans in spring, thereby acquiring a first shade tolerance coefficient; planting the to-be-detected soybeans in the wide row of the corns in summer; inter-planting the soybeans with the corns, and as a reference, purely planting the to-be-detected soybeans in summer; after maturing and harvesting, respectively detecting the grain outputs of the inter-planted to-be-detected soybeans in summer and the purely planted to-be-detected soybeans in summer, thereby acquiring a second shade tolerance coefficient; and comparing the first shade tolerance coefficient with the second shade tolerance coefficient and then detecting the shade tolerance of the soybean. By using the detecting method, the tests for corn-soybean intercropping and corn-soybean inter-planting can be performed simultaneously in the same field, the shade tolerance and the strength of the shade tolerance of the soybeans at different growing stages can be detected, the practicability is excellent, and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for detecting shade tolerance of soybeans. Background technique [0002] In the hilly and mountainous areas of southern my country, soybeans are often intercropped or interplanted with corn. This three-dimensional planting method can not only improve the utilization rate of land, light, heat, water and other resources, but also maintain water and soil, improve soil fertility, and increase crop yield. Field surveys show that the planting of spring soybeans and summer soybeans is the most common type in the southern region, accounting for more than 95% of the total soybean planting area. Spring soybeans and spring corn are sown at the same time in spring, and soybeans are sown between corn rows, and harvested almost at the same time in summer and autumn. The two crops have a long symbiotic period, which is called corn-soybean intercropping; Sow soybeans betw...
