Directional regulating agent of rhizosphere microorganism and nematode containing saturated fatty acid

Abstract

The invention relates to a directional regulating agent of rhizosphere microorganisms and nematodes containing saturated fatty acids. The description describes the effect of natural active substance saturated fatty acids (caprylic acid and capric acid) on controlling soil harmful pathogenic microorganisms, and describes the effect of mixtures with different ratios of caprylic acid and capric acid on modifying soil with biological disorders. Meanwhile, the description describes the control effect of plant source material mixtures (only including castor plant residual bodies and rapeseed cakes) on plant pathogenic nematodes - root-knot nematodes. Finally, the the description describes the modification of combined saturated fatty acids (caprylic acid and capric acid) and plant source materials (castor plant residual bodies and rapeseed cakes) to soil biological disorders. The directional regulating agent of rhizosphere microorganism and nematode containing saturated fatty acids are used to treat soil, which can reduce the effect of soil biological disorders on plant growth. The invention has low production cost, significant effect, and is easy to be popularized.

Description

technical field [0001] The present invention relates to a rhizosphere microbe and nematode directional regulating agent containing saturated fatty acid (caprylic acid and capric acid) and plant source material (castor plant residue and rapeseed cake) to soil biological barriers method of effective control. Background technique [0002] The vegetable industry is one of the main pillar industries of my country's agriculture. According to the agricultural statistics of the Ministry of Agriculture, in 2009, the sown area of ​​vegetables nationwide was 273 million mu, an increase of 4.94 million mu over the same period last year; the total output was 602 million tons, an increase of 26.84 million tons over the same period last year; Kilogram. By the end of 2008, the total output value of my country's facility vegetables reached 410 billion yuan, accounting for 51% of the total vegetable output value. [0003] However, with the increase in the area of ​​facility vegetable land ...

Problems solved by technology

[0003] However, with the increase in the area of ​​facility vegetable land and the increase in utilization frequency, the continuous cultivation of the same or closely related plants in the same plot will lead to a significant decrease in the quality and yield of the plants after the second crop, and a significant increase in the frequency of pests and diseases. It is getting more and more serious. This kind of crop disease and insect pests are obviously serious, and the quality and yield of products are obviously reduced, which is called continuous cropping obstacle.

Under facility cultivation conditions, crops grow under closed or semi-closed conditions, and field management measures are difficult to implement, resulting in frequent occurrence of crop diseases and insect pests and physiological diseases caused by nutrient imbalance, and continuous cropping conditions further aggravate the occurrence of diseases, soil The quality has also gradually declined, and even caused the greenhouse to be deserted

Due to reasons such as high investment cost, limited available land area, and cultivation habits and skills, the continuous cropping obstacles of growing vegetables (mainly cucumbers, eggplants and tomatoes) under protected cultivation conditions are becoming more and more serious. Statistics show that 20-40% of There are different degrees of continuous cropping obstacles in protected cultivation, which cause huge economic losses every year, and the problem is very prominent. It has become the primary problem to be solved for the sustainable development of vegetables in our country and our city
