specific Embodiment approach 1

[0010] Specific embodiment one: the method for the soil improvement of planting blueberries of the present embodiment is carried out according to the following steps:

[0011] 1. In summer, according to every 1000m 2 Apply 2,500-3,000kg of fermented furfural slag to the land, apply the fermented furfural slag evenly on the land to be improved, and plow to fully mix the fermented furfural slag with the soil;

[0012] 2. After 1 to 1.5 months, according to every 1000m 2 The standard of land application is 2500-3000kg of peat, 1500-2000kg of sawdust and 1000-1500kg of organic fertilizer. Apply peat, sawdust and organic fertilizer on the land treated in step 1, and turn till the peat, sawdust and organic fertilizer are mixed with the soil. mix well;

[0013] 3. Manual weeding on the plots treated in step 2;

[0014] 4. In the spring of the second year, dig the ground and ridging to complete the soil improvement.

specific Embodiment approach 2

[0015] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the fermented furfural residue is obtained after stacking the furfural residue for more than 2 years. Others are the same as the first embodiment.

[0016] The color of the fermented furfural residue in the present embodiment is dark black.

specific Embodiment approach 3

[0017] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that in the step one, plowing makes the fully mixing of fermented furfural slag and soil refer to: the deep soil of 25~30cm in the land surface and fermented furfural The slag is mixed evenly. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a soil improvement method, in particular to a soil improvement method for planting blueberries. The method mainly solves the technical problems that existing blueberry planting soil improvement measurements affect soil organism conditions, are high in cost and have toxic action on blueberry roots. The method includes the steps that firstly, fermented furfural residues are evenly applied to soil to be improved in summer, and turning plough is performed to make the fermented furfural residues and the soil fully mixed; secondly, after 1-1.5 months, peat, saw dust and organic fertilizer are applied to the soil, and turning plough is performed to make the peat, the saw dust and the organic fertilizer fully mixed with the soil; thirdly, manual weeding is performed; fourthly, soil plowing and ridging are performed in the spring of the next year, and the improvement to the soil for planting blueberries is completed. The pH value of the improved soil is 4.5-4.8, nutrient status of the soil is improved, and the survival rate of transplanted biennial blueberries and the survival rate of six-year-growing-period blueberries can reach 95-96% and 96-97% respectively. The method is used for blueberry cultivation.

Description

technical field [0001] The present invention relates to soil improvement methods. Background technique [0002] Blueberry is listed by the International Food and Agriculture Organization as one of the five major health foods for human beings, and it has also entered the ranks of the world's third-generation fruits. At the same time, according to experts' speculation, blueberry will become one of the most promising fruit tree species in the world in this century. However, blueberry cultivation has extremely strict requirements on soil, which has become one of the important factors restricting blueberry cultivation and commercial cultivation. The most suitable pH value of the soil during normal growth of blueberries is 4.0-4.8. When the pH value is higher than 5.5, it will cause iron deficiency and chlorosis of blueberries, stunted growth and even death. The traditional way to reduce soil pH value is to apply sulfur. In organic cultivation, sulfur has insecticidal and bacter...
