Problems solved by technology

However, the effect of this kind of fertilizer is partial. After all, it does not disinfect the entire soil cultivation layer. It has not fundamentally changed the micro-ecological system inside the soil caused by continuous cropping for many years, so the effect of eliminating harmful microorganisms and insect eggs is limited. , also short-lived

example 1

[0031] Example 1. A company in a certain place has 200 mu of plastic greenhouse vegetable land, which belongs to the first type of soil with poor aggregate structure. Due to the application of a large amount of chemical fertilizers, it has hardened. The vegetable field has been planting white peppers continuously for 10 years. The average yield of fresh peppers per mu in the first five years is about 400kg. Since the sixth year, the yield has decreased year by year, and the average annual yield is less than 200kg / mu. The main reason is that there are many diseased plants and the growth is not large. Afterwards, the organic formulation and method of the present invention are used for treatment. The specific method is to dig out the root system after harvesting the peppers in August and September every year, remove all the pepper trees, and then evenly sprinkle plant powder on the ground, and the amount of molasses added is zero.

example 2

[0034] Example 2. A company in a certain place has a vegetable greenhouse of 300 mu, which belongs to the third type of soil. Cucumbers have been planted continuously for 7 years. In the first three years, the average yield of cucumbers per mu was 5000 catties, and the output gradually decreased in the fourth year, less than 1800 catties per year. The main problem is that cucumber trees suffer from frequent diseases, weak growth, and obvious continuous cropping obstacles. Process with the method of the present invention afterwards, draw out 5 mu wherein simultaneously as contrast. The planting management of the control plot was the same as in previous years. The method steps of the present invention's treatment, and the time are basically the same as those of Example 1. Just after the anaerobic treatment of the soil by sprinkling plant powder, add 30% molasses water (dilute with water when sprinkling to reduce viscosity). The total amount of two successive treatments is bas...

Abstract

The invention relates to an organic preparation for sterilizing vegetable continuous cropping obstacles sick soil and application. The organicpreparation is a composition of molasses and one or more dry powder of the following plant materials: reed, potato rattan, straw, wheat straw, pea straw, bagasse, broad bean straw and corn straw. The weight percent of the molasses is 0-100%. Before use, the dry plant powder and the molasses are respectively packed and are used sequentially. A use method comprises the following steps: uniformly spreading the dry plant powder or the molasses on a vegetable ground with continuous cropping obstacles according to a proportion set in advance, carrying out tillage by using a rotary cultivator, and mixing and buring the plant powder or the molasses in a soil plough layer; uniformly watering in 30-80 tons in per mu, and keeping soil moist; and covering the land by using plastic films to isolate the soil from air; controlling the temperature of the soil to be 25-50 DEG C, and controlling the redox potential to be minus 60 mv or below to form an anaerobic intense oxidation reduction state; and removing the films after keeping the anaerobic intense oxidation reduction state for 3-4 weeks. Fusariumoxysporum, root-knot nematode and the like in the soil can be killed effectively, and continuous cropping obstacles are eliminated.

Description

technical field [0001] The invention relates to a vegetable planting technology, in particular to an organic preparation for disinfection of vegetable continuous cropping obstacle diseased soil and its application. Background technique [0002] Consumers' eating habits lead to a preference for certain vegetable varieties in the consumer market, prompting vegetable farmers or other growers to plant the same variety of vegetables on the same land for many years, that is, continuous cropping. As a result, more and more serious obstacles to continuous cropping have been caused, causing problems such as aggravation of vegetable diseases and insect pests, deterioration of plant growth status, and decline in yield and quality. Continuous cropping obstacle is a common phenomenon in the cultivation of various crops. It is that the micro-ecological environment in the soil is more stable due to the planting of the same variety of crops for many years, resulting in the proliferation of ...
