Embodiment 1

[0015] Embodiment 1: the present invention is a kind of soil comprehensive regulation and control method of cultivating blueberries, and the steps are as follows:

[0016] Step 1: raw materials include: sulfur powder (325 mesh) with a sulfur content of 99.9%, decomposed larch needles, pine bark, acidic compound fertilizer K 2 SO 4 : Total nutrient content ≥ 45%, N-P 2 o 5 -K 2 O 12-21-12;

[0017] Step 2: After the planting area is selected, random multi-point soil samples are mixed, and the pH value of the soil sample is measured by potentiometric method, which is the pH value of the soil. The optimum soil pH value for blueberry cultivation is 4.5-4.8. If the measured soil pH value is higher than the optimum soil pH value, apply sulfur powder for adjustment. The standard for applying sulfur powder is: if the soil pH value decreases by one unit, then apply 16kg / 100m 2 Sulfur powder, when soil pH drops from 5.5 to 4.5, every 100m 2 Apply 16kg of sulfur powder, sprinkle th...

Embodiment 2

[0022] Example 2: The Greater Khingan Mountains region is located in the northernmost part of my country, adjacent to the Lesser Khingan Mountains in the east, bounded by the Greater Khingan Mountains in the west and the Inner Mongolia Autonomous Region, bordering on the vast Songnen Plain in the south, and bordering Russia on the central line of the main channel of Heilongjiang in the north. 121°12' to 127°00', 50°10' to 53°33' north latitude. The climate in the forest area belongs to the cold temperate monsoon zone. The annual average temperature of the region is -4.9°C, the extreme minimum temperature is -47°C, and the extreme maximum surface temperature is 57°C-60°C. The maximum depth of frozen soil can reach 2.5 meters. Night frosts end in late May.

[0023] The meadow soil of the 18th Station Forestry Bureau of Daxing'an Mountains is regulated according to the method of the present invention, and the steps are as follows:

[0024] (1) The soil pH value of the cultivate...

Embodiment 3

[0030] Embodiment 3: Implement regulation and control to the meadow soil of Daxinganling 18 station center nursery:

[0031] (1) The soil pH value of the cultivated blueberry field was measured by the potentiometric method, and the soil pH value was 5.37. The soil pH value is higher than the pH value suitable for blueberry cultivation, so the soil pH value should be adjusted to about 4.5. So apply 16kg / 100m 2 Sulfur powder, apply evenly throughout the garden, and mix well after deep plowing.

[0032] (2) Excavating a trench with a width of 0.5m and a height of 0.2m, after mixing the well-decomposed pine needles and pine bark by volume in a ratio of 1:1, the volume percentage of the mixture and soil is 30%:70 % after mixing, fill back into the colonization groove.

[0033] (3) According to 3kg / 100m 2 Amount of application, acidic compound fertilizer K 2 SO 4 As a base fertilizer, it can be leveled by raking (5-10cm) after spreading.

[0034] (4) Carry out colonization ac...

Abstract

The invention provides a method for comprehensively regulating and controlling soil for cultivating blueberries, which is simple and easy, and can ensure that the pH value of the soil is stabilized within an appropriate internal of soil pH values for a long time, promote the growth of the blueberries, remarkably improve the yield of the blueberries, and promote the quality of fruits. Raw materials comprise sulfur powder with the sulfur content of 99.9 percent (325 meshes), decayed larch needles, pine barks, and an acid compound fertilizer K2SO4, wherein the total nutrient content is more than or equal to 45 percent (N-P2O5-K2O, 12-21-12). The method comprises the following steps of: determining the pH value of a soil sample by potentiometry, and applying the sulfur powder to adjust the soil if the pH value of the soil is greater than the pH value which is mostly suitable for the soil; and spreading the acid compound fertilizer K2SO4 which serves as a base fertilizer according to the application amount of 3kg/100m2, and shallowly turning the soil in the depth of 5 to 10cm after fertilizer application. By the method, the pH value of the soil can be reduced to 4.5 and can be stabilized within the range for 3 years, so the soil is extremely suitable for planting the blueberries. When the blueberries are planted in improved areas, the aboveground biomass is increased by about 5 times, and the content of mineral nutrition and the content of trace elements in the soil are both greatly increased.

Description

(1) Technical field [0001] The invention relates to soil improvement technology, in particular to a soil comprehensive control method for cultivating blueberries. (2) Background technology [0002] Soil pH is one of the important basic properties of soil, an indicator of soil formation process and maturation and fertilization process, and an important chemical indicator that affects soil physical and chemical properties. Soil pH has a great impact on the form and availability of nutrients in the soil, as well as on the physical and chemical properties of the soil, microbial activities, and plant growth and development. In soil, the most closely related to pH is the chemical elements in the soil-plant system, which directly affects the existence, availability, migration and transformation of various elements in the soil. Mastering the pH value of soil has important theoretical and practical significance for soil diagnosis, rational fertilization and improvement of crop yield...
