specific Embodiment approach 1

[0018] Specific implementation mode one: the present implementation mode cranberry field shallow root layer soil composite strengthens the method for adjusting acid according to the following steps:

[0019] 1. Sulfur powder application method: Determine the amount of sulfur powder application based on the initial pH value of 0-20cm soil and the target pH value to be reduced. The initial pH value is 5.5-6.0, the target pH value is 4.5-5.0, and 300kg of sulfur powder is applied per hectare; The pH value is 5.0-5.5, the target pH value is 4.0-4.5, and 200kg of sulfur powder is applied per hectare; evenly spread on the ground before the cranberry planting, and the mechanical rotary tillage mixes 15cm;

[0020] 2. Spray urea phosphate: plant cranberry seedlings, spray 500-1000 times aqueous solution of urea phosphate after planting, spray on the roots of planted seedlings, spray 3-4 times in a growing season, and use urea phosphate to quickly reduce root damage. The role of soil p...

specific Embodiment approach 2

[0023] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in step 1, the initial pH value is 5.6-5.9, the target pH value is 4.6-4.9, and 300 kg of sulfur powder is applied per hectare. Others are the same as the first embodiment.

specific Embodiment approach 3

[0024] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that in step 1, the initial pH value is 5.1-5.4, the target pH value is 4.1-4.4, and 200 kg of sulfur powder is applied per hectare. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention belongs to the field of soil improvement, regulation and control, and particularly relates to a composite enhanced acid regulation method for shallow root layer soil of a cranberry field, in particular to a composite enhanced acid regulation method for a turfy soil cranberry field. The invention aims to solve the problems that the acidity of turfy soil in northeast China is low, and the acid regulation effect is slow when sulfur is applied. The method comprises the following steps: 1, application of sulfur powder; 2, spraying application of urea phosphate; 3, surface application of pine needles; and 4, water management. The composite acid regulation method is adopted for the shallow root layer soil of the turfy soil cranberry field, rapid acid regulation and acidification effect maintaining are enhanced, the rhizosphere soil acidity needed by cranberry field planting survival is ensured, the survival rate is increased, and technical guarantee is provided for rapid and efficient cranberry planting.

Description

technical field [0001] The invention belongs to the field of soil improvement and control, and in particular relates to a method for compound and intensified acid regulation in peat soil cranberry fields. Background technique [0002] Cranberry (Vacinium Macrocarpon) is an acid-loving perennial plant of the Rhododendron family. It is suitable for growing on moist soil with a cool climate, high organic matter content, and a pH value of 4.0-5.0. Practice has proved that peat soil is rich in natural organic matter, loose soil, strong water retention, suitable for cranberry planting. The widely distributed peatland resources in the eastern part of Northeast China provide favorable conditions for the development of efficient cranberry agriculture. However, the soil acidity of the peatland in Northeast China is not strong, and the pH value is mostly in the range of 5.0-6.0, which is beyond the optimum pH range for cranberry growth. In addition, the thickness of the peat soil lay...
