Embodiment Construction

[0008] Inhibition experiments of soybean meal on plant seed germination and rooting are given below.

[0009] Weigh 2 mg, 6 mg, 10 mg, 14 mg, 20 mg, and 28 mg of soybean meal powder with an electronic balance, put them into 100 mL Erlenmeyer flasks with double-layer filter paper at the bottom, add 2 mL of deionized water and shake repeatedly, so that the soybean meal The processing amount of flour according to the mass ratio (soybean flour: water) is: 1mg / mL, 3mg / mL, 5mg / mL, 7mg / mL, 10mg / mL, 14mg / mL. The experimental plants are listed in Table 2-1. The seeds of the tested plants were placed in Erlenmeyer flasks treated with different soybean meal, sealed with Parafilm and placed in a light incubator, with 2 mL of deionized water as the control, and each treatment was repeated 3 times. Culture conditions: 12 hours of light per day, temperature of 25°C, and light intensity of 1500 lx. Except for 16 days of cultivation of water centipede, the cultivation time of other plant seed...

Abstract

The application of bean pulp in preparing for weedicide relates to the bean pulp and the weedicide, in particular to the bean pulp which is an auxiliary product made from farm product has the effect of restraining plant seeds sprouting and rooting, which can be used for preparing for natural pre-emergence weedicide and is especially applied to preventing and curing lawn weeds. The invention provides the application of the bean pulp in preparing for the weedicide. The bean pulp is a side product obtained after soybean is processed for extracting bean oil. The shape of the bean pulp is irregular fragmentary shape generally with light yellow to sandy beige and the smell of baked soybean and is insoluble in water. The main components of the bean pulp are 40 to 48 percent of protein, 2.5 to 3.0 percent of lysine, 0.6 to 0.7 percent of tryptophan and 0.5 to 0.7 percent of methionine. A plurality of experiments in which the bean pulp restrains the plant seeds sprouting and rooting testify that the bean pulp has obvious restraining effect on plant seeds sprouting and rooting, so restraining the activity of the plant seeds sprouting and rooting by the bean pulp can be applied to preparing for a natural nuisanceless pre-emergence weedicide.

Description

technical field [0001] The present invention relates to soybean meal and herbicide, in particular to the inhibitory effect of soybean meal, an auxiliary product of agricultural product processing, on the germination and rooting of plant seeds, which can be used to prepare natural pre-emergent herbicides, and is especially used in the control of lawn weeds. Background technique [0002] Weed control is one of the main problems in agricultural ecosystems and urban lawn management. Chemical weeding methods are currently the most common weed control methods due to their cheapness, labor saving and high efficiency. However, as a large number of chemical pesticides are applied to the soil, causing environmental pollution, endangering human health and adverse effects on biodiversity, people began to seek environmentally friendly natural biosourced herbicides to control weeds, and some encouraging results have been achieved. Progress. Since the 1990s, Christians of Iwoa State Unive...
