preparation example Construction

[0028] The preparation method of eucalyptus allelopathic compound comprises the following steps:

[0029] (1) Take the root system of Eucalyptus, cut it into 4~8mm sections, soak in the nutrient solution for 10~12h according to the mass ratio of 1:4~7, wet ball mill at 300~350r / min for 30~45min at 35~45℃, filter, Wash the filter residue with 2 to 4 times deionized water to obtain a lotion, add the lotion to the filtrate to obtain a mixed solution, evaporate the mixed solution in a vacuum at 45 to 60°C, and concentrate under reduced pressure to 15 to 35% of the original volume to obtain Eucalyptus root extract, spare;

[0030] (2) According to the number of parts by mass, take 7~15 parts of eucalyptus root grass-free soil, 0.5~1 part of NaH 2 PO 4 , 30~50 parts of glucose, 1~3 parts (NH 4 ) 2 SO 4 , 5~10 parts of sodium glutamate, 16~25 parts of perilla oil, 3~8 parts of KCl, 0.2~0.6 parts of CaCO 3 , 0.4~0.8 parts of MgSO 4 ·7H 2 O, 0.1~0.3 copies of VB 12, 600~800 p...

Abstract

The invention discloses a rice herbicide, and belongs to the field of pesticides. The rice herbicide has the advantages that eucalyptus root systems are taken as a raw material, through culture of nutrient solution, wet ball-milling and other operation, leaching of phenolic acid substances secreted by the root systems is significantly improved, grass-free soil of the eucalyptus root systems is taken as a raw material, through rejuvenation and fermentation of various nutrients, various organic matters are generated, an allelopathic compound of eucalyptus can be combined with the surrounding growth environment to form a biological allelopathic system when being in use, the inhibiting effect on weed is significant, the ability of rice to absorb nutrients is strengthened, and the effect of biological weed suppression and weeding is achieved; and the rice herbicide solves the problems that an existing rice herbicide has large biotoxicity, and is not conductive to rice ears and fruits.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a rice herbicide. Background technique [0002] Rice is one of the most important food crops, but it needs efficient and green control of pests in production to prevent them from reducing food production. Among the weeds in paddy fields, there are many factors that lead to the reduction of rice production than weeds. At present, chemical weeding has become a common method, and there are many kinds of weeds in paddy fields. The corresponding herbicides can effectively control the impact of weeds on paddy fields. . Combined with the analysis of morphological differences, the weeds in rice fields can be divided into the following categories: the first is the monocotyledonous weeds, the second is the dicotyledonous weeds, and the grasses and Cyperaceae weeds It is a monocotyledonous weed, and broadleaf weed is a dicotyledonous weed. It is of certain reference value to choose different her...
