drug application time: 12 july 2016
test site: changqingyuan farm, huiji district, zhengzhou city
testers: wang haiting, yu zhaoli and wang jianwei
i. test purpose
field experiments were conducted to verify the effects of "short and more harvested soybeans" on plant height, leaf and plant growth, and to provide practical basis for the promotion and application of "short and more harvested soybeans" products.
ii. test materials
pharmaceuticals: "soybean is short and receives more than 1 1" (60g) water agent
pesticide application: 15kg manual sprayer.
iii. test design
3.1 dose setting
pharmaceutical treatment: "soybean is short and harvested more" (500 times liquid)
control: no medication was used.
spraying method: spraying uniformly on the leaf surface.
3.2 trial arrangements
one treatment was arranged: 500 times liquid.
processing area: 2 square meters, each processing and set three repetitions.
3.3 investigation methods and contents
method of investigation: five-point sampling method was used and five points (2 trees per point) were investigated for each treatment.
survey content: plant height, leaf and plant growth of soybean
survey time: july 19, 2016 (first survey).
iv. results investigation
effects of 4.1 on soybean leaves (see figure below)
effects of 4.2 on plant height of soybean (see figure below)
v. conclusion and discussion
before the first flowering of soybean, the r&d personnel of our company carried out the field experiment of controlling vigorous growth and increasing yield of soybean in order to verify the effect of "short and more harvest of soybean". according to the set test plan, 500 times of liquid foliage was sprayed on the short and more harvest of soybean, and 7 days after the use of this medicine, the results showed that the use effect of this product in the present growth stage of soybean was as follows: promoting the thick green leaves of soybean, significantly reducing plant height, and very much. good control of soybean growth, according to the current use of this product shows good results, in order to further verify the impact of soybean short and excessive harvest on soybean flowering and fruiting and yield, still need to continue tracking investigation.
