New method for overcoming continuous cropping obstacle of apple

Abstract

The invention provides a new method for overcoming continuous cropping obstacles of apples, comprising the following steps: 1. adding water to a mixture of 60% of chicken manure, 10% of sheep manure, 10% of cow manure, 10% of maize straw and 10% of garlic straw (cauloid) according to a volume ratio, and then fully fermenting into fluid; 2. pouring the fermented fluid into tree pits with irrigation water together within 30 days after new planted young apple trees sprout in spring, and then applying a nitrogen, phosphorus and potassium compound fertilizer based on the conventional amount into the fermented fluid for one time in the middle ten days of June, July and August in the same year respectively; and 3. applying the fermented fluid into the tree pits for one time in early May, early June, early July and the middle ten days of August in the second year and the third year respectively after planting the trees, and meanwhile applying the nitrogen, phosphorus and potassium compound fertilizer based on the conventional amount. In the method, the mixture amount in orchard is 1m<3> per mu every time. Using the method can effectively overcome the continuous cropping obstacles of the apples.

Description

(1) Technical field [0001] The invention relates to a new method for overcoming obstacles in continuous cropping of apples, belonging to the fields of fruit tree cultivation and disease prevention and control. (2) Background technology [0002] Continuous cropping obstacle (replantation disease or ground avoidance phenomenon) refers to that the continuous planting of the same crop in the same field leads to the inhibition of plant growth, which is commonly found in fruit tree species such as apples, pears, grapes, peaches and most crops in all countries in the world. The causes of apple continuous cropping obstacles are complicated, and they can be summarized as follows: one is the effect of harmful microorganisms, especially harmful fungi. The second is the hazards of self-toxic substances. The third is the imbalance of soil nutrients. Continuous cropping obstacles can cause low survival rate of newly planted fruit trees, weak tree vigor, serious pests and diseases, low y...

Problems solved by technology

Second, the hazards of self-toxic substances

Third, soil nutrient imbalance

This method has a good control effect, but there are many problems such as high cost, chemical damage, and destruction of the atmospheric ozone layer. According to relevant international conventions, it will be gradually banned

In addition, the use of physical measures such as solar radiation and steam can also achieve the purpose of soil disinfection, but the application range and effectiveness are very limited.

(3) Biological control: A disease control method that uses some beneficial bacteria to suppress the number of pathogenic bacteria in the soil or interfere with the infection of pathogenic bacteria on parasitic plants, but the control effect is not ideal

(4) Using apple rootstocks resistant to continuous cropping obstacles: According to reports, rootstocks resistant to continuous cropping apples have been bred in the United States, but such rootstocks have not been widely used in production, and their effects and adaptability need to be further verified

(5) Improving soil: The guest soil method is commonly used, that is, the tree hole soil is replaced with non-continuous cropping soil, and the effect is good, but this method is time-consuming and labor-intensive, and non-continuous cropping soil resources are also limited

[0004] Although researchers have done a lot of research on measures to overcome apple continuous cropping obstacles and achieved certain control effects, there are few reports on methods that make full use of waste resources and are eco-friendly, simple, easy to popularize, and effective.
