Abstract
Introduction
The Ministry of Agriculture and Rural Affairs' "Measures for the Management of Agricultural Product Quality and Safety Commitment Certificates" has been officially implemented, and the fruit and vegetable planting bases that pursue quality have laid out low-cost and effective green prevention and control technologies to reduce the use of pesticides, reduce pesticide residues, or organic planting.
As the world's first enterprise to break through the on-site fermentation technology of biocontrol bacteria, Green Nitrogen Biotech provides solutions for high-end bases and agricultural material dealers - to move the "fungicide factory" to the field, so that the functional microorganisms of instant fermentation can work in the field in the state of "special forces", starting from soil modification, promoting growth, preventing insects and diseases, and achieving fertilizer control, drug reduction, quality and production increase!
Use bacteria 4 times to effectively prevent and control cowpea root diseases
Winter and spring are the main planting periods of cowpea in tropical regions such as South China and Southwest China, and it is also the peak period of pest occurrence and drug use.
| Category | Application effect of green nitrogen live bacteria |
| Place of application | Shiping County, Yunnan |
| Species | Trichoderma hartz + Bacillus compound |
| frequency | 2 L/mu, 4 times, used once every two weeks |
| Effect | Efficiently prevent and control cowpea root diseases, and use fungus root health after the rainy season |
| Benefits | One mu of bacterial solution is 80 yuan, and the prevention effect of root rot is remarkable |
Leek and leek maggots control to recover the loss of a single shed of 10,000 yuan
In late December, some leek sheds of Beijing Shiweixian Organic Farm broke out with leek pests, and the farmer used four products that could not be suppressed.
| Category | Application effect of green nitrogen live bacteria |
| Place of application | Shunyi District, Beijing |
| Species | Bacillus thuringiensis (Bt) |
| frequency | 5 L/mu, 1 time |
| Effect | After 5 days, the density of the leek maggot mouth decreased by 95%, and 99% was killed in 7 days, and new roots grew |
| Benefits | invested more than 100 yuan of bacterial liquid per mu to recover the loss of tens of thousands of yuan in a single shed |
Celery is used for bacteria 3 times, resistant to heavy stubble, and increases yield by 33% per mu
Traditional continuous cropping faces multiple challenges such as soil compaction, reduced fertility, difficult pest prevention and control, and difficulty in improving yield.
| Category | Application effect of green nitrogen live bacteria |
| Place of application | Changping District, Beijing |
| Species | Bacillus compound |
| frequency | 2 L/mu, 3 times |
| Effect | Resistant to heavy stubble, significantly promote the growth and development of celery, and the stem is strong and the tillers increase |
| Benefits | With the input cost basically unchanged, the yield increased by 33.18%, and the production-investment ratio was as high as 8.19, far exceeding the traditional planting method! |
The "whole process of bacterial control" helped strawberries increase their income by 5,000 yuan/mu
The technical solution of strawberry "bacterial control and multiplication of benefits" is a technical support for the healthy growth and high-quality and high yield of strawberries from many aspects such as soil environment improvement, plant rooting and growth, and pest control for strawberry planting.
| Category | Application effect of green nitrogen live bacteria |
| Place of application | Jiaxing City, Zhejiang |
| Species | Bacillus compound, Trichoderma hartz |
| frequency | 34 times, 500 mL/time, drip irrigation with water |
| Effect | The occurrence of strawberry diseases is reduced by 70%, saving a lot of labor |
| Benefits | The investment per mu is 600 yuan, the yield per mu increases by 8.7%, the income increases by 5,000 yuan/mu, and the labor cost decreases by 400 yuan/mu |
