Problems solved by technology

However, how to conduct rapid quantitative monitoring of weeds under the cultivation and farming modes of rice-wheat, rice-rape, rice-green manure, and rice-winter field, and to select comprehensive weed control strategies based on quantitative monitoring to quickly reduce the density of weeds , there is no specific technology related to reducing the frequency and amount of herbicide use
In particular, how to quickly judge the dominance level (damage level) of weeds based on indicators such as the abundance and coverage of weeds in the field, there is no clear data index as a basis

Embodiment 1

[0044] Implementation time: 2016 - 2018.

[0045] Implementation location: Zhengyang planting professional cooperatives in Haocuan Township, Suqian City, Jiangsu Province.

Embodiment approach

[0046] Implementation: This test is a model of rice-Meclen mode, winter planting wheat, wheat varieties as "Huai Ma 26", planting amount is 35kg / mu, plant rice, rice varieties are "Lianyin No. 11", transplanting ( Machine transplantation) line spacing 30cm, strain of 20cm, 5 seedlings per hole. Before the experiment, the weeds were conventionally in the test field. "One closed + secondary stem" during wheat plantation, that is, the soil is closed before the seedlings, spray; in the 3 leaves of wheat, use stem herbicide spray treatment; after the wheat 4 leaves Before the pulling, the herbicide was treated with a stem leaf. During the rice planting, herbicides are used as "a two kills, three supplements", that is, in the seedlings of seedlings, the seedling agent is applied, and the seedling period (before the weed 3 leaves 1 heart) spray stem sheaves In the late stage of the seedlings, the stem treatment agent was supplemented.

Embodiment 2

[0053] Implementation time: 2016 - 2018.

[0054] Implementation location: Xiajiahu, Lingqiao Township, Huaiyin District, Huai'an City, Jiangsu Province.

[0055] Implementation: This test is a model of rice-Meclen mode, winter planting wheat, wheat varieties as "Huai Ma 26", planting amount is 35kg / mu, plant rice, rice varieties are "Lianyin No. 11", transplanting ( Machine transplantation) line spacing 30cm, strain of 20cm, 5 seedlings per hole. Before the experiment, the weeds were conventionally in the test field. During wheat plantation, "one closed + one stem leaf", that is, the soil is closed after the seedling of wheat, sprayed; in the 3 leaf of wheat, using stem shell herbicide spray treatment. During the rice planting, herbicides are used as "a two kills, three supplements", that is, in the seedlings of seedlings, the seedling agent is applied, and the seedling period (before the weed 3 leaves 1 heart) spray stem sheaves In the late stage of the seedlings, the stem tre...

Abstract

The invention discloses a quantitative monitoring method for weeds, which can be applied to guide the selection of weed prevention and control measures, belongs to the field of plant protection, and specifically relates to a four-level visual inspection method using seedling stage, growth stage Sample method, seven-level visual inspection method at maturity stage, soil seed bank survey before planting, rapid and quantitative monitoring of farmland weeds and weeds under different farming modes throughout the growth period, and implement according to the quantitative indicators of weeds and weeds Targeted weed control strategies to achieve the goal of continuous weed control. Continuous monitoring can clarify the occurrence and dynamics of weed damage, implement reasonable weed control measures, reduce the frequency and amount of herbicide use, effectively control the occurrence of weed damage, significantly reduce planting costs, and reduce environmental pollution.

Description

Technical field [0001] The present invention belongs to the field of crop cultivation management, and specific to a quantitative monitoring method of weeds. Background technique [0002] Weeds are one of the most important factors that lead to production of crops. Weeds are mainly based on chemical herbicides. With the intensification and scale development of agricultural production in my country, this dependence will also be aggravated. In the rice-Mai (oil), a season of rice will take "a" one "," two killed "," three supplements ", using three herbicides, wheat or rapesets will also use" a "two" two Use the herbicide use, if the weed base is high, the "second supplement" needs to use a herbicide of the undergraduate weed and the weeds of the weeds, a total of 6 times. However, the long-term large amount of chemical herbicide can lead to serious pollution of farmland soil and water source, bringing serious environmental crises, causing chemical residues of agricultural products ...
