Problems solved by technology

[0002] Obstacles to continuous cropping (heavy cropping) of apples generally occur, and the obstacles to continuous cropping are manifested as short plants, reduced yield and quality, unhealthy root system, serious pests and diseases, etc., which bring huge losses to apple operators
The main cause of apple continuous cropping obstacles is harmful fungi in the continuous cropping soil, such as Fusarium fungi, Pythium fungi, Rhizoctonia solani fungi, etc. For the above reasons, crop rotation (planting annual crops), soil Measures such as fumigation and inoculation of antagonistic bacteria can reduce the obstacles to continuous cropping of apples. The mechanism by which crop rotation can reduce the obstacles to continuous cropping of apples is to change the structure of harmful bacteria in the continuous cropping soil, including the reduction of the number of harmful fungi. The ideal effect can only be achieved by rotating crops for more than three years. Therefore, considering economic benefits, it is not easy for orchard operators to accept and it is not conducive to the timely renewal and construction of old orchards.

Embodiment 1

[0005] Example 1—Validation of Potted Plants

[0006] On March 11, 2013, the Pingyi sweet tea seeds that had undergone stratification and germination were sown on the seedling tray for seedling cultivation. When the seedlings grew to the third true leaf, the seedlings with basically the same growth were transplanted to the continuous cropping soil of each treatment. Middle: There were three treatments in the soil of apple continuous cropping in pots: control (CK), fumigation with methyl bromide (T1), sowing onion seeds in pots one week after transplanting seedlings (T2); 10 pots for each treatment, and 5 seedlings were planted in each pot. In July 2013, the biomass of potted Pingyi sweet tea seedlings for each treatment, the number of soil bacteria, fungi, and real-time fluorescence quantification of the harmful fungus Fusarium oxysporum were measured, and the results are as follows:

Embodiment 2

[0015] Example 2—Field Demonstration

[0016] On December 27, 2013, the old apple orchard was renewed in Longkou, Shandong. First, the old orchard apple trees were removed, and the planting ditch was excavated. The planting ditch was 1 meter wide and 0.8 meters deep. The 1-meter layer and the 0.4-0.8-meter layer of soil are placed separately, and the residual roots in the soil are sorted out as much as possible in combination with ditching. When backfilling in the spring of 2014, the soil at the level of 0.4-0.8 meters was placed on the upper part, and the soil at the level of 0-0.4 meters was placed on the lower part (that is, the positions of the upper and lower soil layers were exchanged). 40 grams of carbendazim with an active ingredient content of 80% is evenly mixed into the tree hole with a width and depth of 0.4 meters, and then the saplings are planted and covered with film. In July of the same year, remove the film and spread the onion seeds within 1 square meter of...

Abstract

The invention relates to a method for alleviating continuous cropping obstacle of apples by mixing cropping of fruits and dwarf shallow root crops. The method comprises the following steps: when constructing a continuous cropping orchard, digging planting furrows prior to winter, respectively placing upper and lower soil layers, backfilling the soil layers in spring, picking up residual roots in the soil, uniformly mixing 40g of carbendazim with an effective component content of 80% in the cave soil, and carrying out mixed cropping on apple saplings and dwarf shallow root crops, such as garlic, onion or brassica juncea. Crop root exudates can inhibit or kill harmful fungi in the continuous cropping soil to alleviate the continuous cropping obstacle of apples finally. The method provided by the invention is simple, easily available in raw materials, environmentally friendly and free of environmental pollution.

Description

(1) Technical field [0001] The invention relates to a method for reducing apple continuous cropping obstacles by mixing fruit trees with dwarf and shallow root crops, and belongs to the field of fruit tree cultivation.
