Composition and method for biologically preventing and treating skyblue broomrape herb

Abstract

The invention discloses a composition and a method for biologically preventing and treating skyblue broomrape herb. The composition mainly comprises the following components: a soil conditioner, a microbial agent, a soil fertility balancing agent and an organic trace element nutritional agent. The method comprises the following steps: (1) soil saline-alkali improvement: from the first drip irrigation after sowing or transplanting, a soil conditioner is dripped into soil; (2) microbial bacterium prevention and control of skyblue broomrape herb: from the second drip irrigation after sowing or transplanting, a microbial agent is dripped into soil; (3) soil fertility balance adjustment: from the second drip irrigation after sowing or transplanting, a soil fertility balancing agent is dripped into the soil; and (4) supplementing foliage nutrition, namely spraying an organic trace element nutritional agent to the crop foliage during the growth period of the crops. The provided composition can efficiently inhibit skyblue broomrape herb, can realize continuous farming and planting, reduces the soil salinity and alkalinity, improves the soil fertility, increases the yield and the income, isenvironment-friendly, and reduces the water and fertilizer consumption. The method is scientific, simple, convenient, low in cost and suitable for agricultural application.

Description

technical field [0001] The present invention relates to a composition and a method for preventing and treating rabies, in particular to a composition and a method for biologically preventing and treating rabies. Background technique [0002] Liedang is a general term for plants of the genus Orobanche Phelipanche of the family Orobanchaceae that live on the roots of parasitic plants. Liedang, also known as unicorn grass, poison root grass, and rabbit crutches, is a common parasitic weed that can seriously affect crop yields in agricultural production. It is mainly distributed in Xinjiang, Gansu, Shanxi, Inner Mongolia, Heilongjiang, Liaoning, Jilin and other provinces have a wide range of host plants. They parasitize on Hami melon, watermelon, muskmelon, pea, broad bean, carrot, celery, tobacco, wolfberry, flax, pepper, tomato, sunflower and other plants and cause harm. Then no income. [0003] Liedang is a parasitic weed, which obtains all nutrients and water from the host...

Problems solved by technology

However, the above two methods all have the same technical defect: there are still 10% of the seeds in the soil that have not germinated. As long as there is one plant that parasitizes in the soil of the second season, there will be tens of thousands or even hundreds of thousands of seeds. Liedang seeds, in the subsequent planting process, Liedang will also appear parasitic and cause harm, this method cannot fundamentally solve the hazards of Liedang

Although the control effect can reach 67%, there is a certain increase in production and the effect of preventing and controlling tobacco stalks, but from the perspective of control efficiency, there are still more than 30% stalks in the soil, and it is impossible to continue planting tobacco in this situation (Li Zhiqiang et al. Field experiment of "Shenhoe" compound microbial fertilizer to control flue-cured tobacco [J]. New Agriculture, 2016, No. 7: 58-59.)

[0017] The existing scheme of crop rotation and stubble rotation advocates the implementation of 4-6 years or even longer crop rotation and stubble rotation for heavy-cropping and scalloped-stubble land. However, the above-mentioned schemes cannot solve the problem of continuous planting of rowan seeds for more than 10 years in the field. The implementation of the stubble prevention and control program is not good in terms of effect or economic benefits, and the land utilization rate is difficult to adapt to the sustainable development of local industries.
