Embodiment 1

[0014] 1. Dusi lingonberry-Tatoudianzidi, the 12th station forest farm of Huma Forestry Bureau in Daxinganling Mountains; the average yield is 39.27g / m 2

[0015] 2. Implementation:

[0016] (1) Keep the soil water content ≥ 60% through irrigation measures;

[0017] (2) Mix urea, diammonium phosphate, and potassium sulfate uniformly according to the mass ratio of 2:3:2; 2 The amount of application is evenly spread; wherein, the N-P in the diammonium phosphate 2 o 5 -K 2 O: 18-22-5; urea (CO(NH 2 ) 2 ) contains nitrogen mass percentage ≥ 46%; potassium sulfate contains K 2 O mass percentage ≥ 50%);

[0018] (3) Sulfur powder according to 50g / m 2 The amount of application is carried out by spreading. Mix sulfur powder and fine loam that has passed through a 4-mesh sieve at a ratio of 1:3 by volume, and then spread it evenly. The fine loam is mixed with water and passed through a 4-mesh sieve to finally reach a water content of 28%.

Abstract

The invention relates to a comprehensive control method for increasing a yield of a Vaccinium uliginosum, and provides a comprehensive control method with strong operability and a good yield-increasing effect aiming at the Vaccinium uliginosum. Limiting factors of affecting yield increase are removed by measures of mainly improving soil humidity for plane growth of the Vaccinium uliginosum, adjusting soil acidity and supplying proper available nutrient and the like. The moisture content of soil can be adjusted and determined by field scientific tests for many years according to ecological and biological characteristics of the Vaccinium uliginosum; the soil acidity can be effectively stabilized and the yield per unit area can be improved according to a mass ratio under a condition of adding sulphur powder, urea, diammonium phosphate and potassium sulphate. According to the comprehensive control method, a pH value of the soil is stabilized at an interval of 4.5-5.0, and the yield per unit area can be improved over 80%.

Description

technical field [0001] The invention relates to a comprehensive control method for Vaccinium uliginosum L., in particular to a comprehensive control method for adjusting soil moisture, soil acidity and plant nutritional status of Vaccinium uliginosum L. Background technique [0002] Bilberry is a unique wild small berry in the alpine region of my country. It has been in a pure wild state. With the development of economy, the resources of Bilberry have been developed rapidly, and the demand for its fruit is also increasing. Since the yield of Dusi lingonberry is greatly affected by natural conditions, necessary tending measures are the main way to promote production in recent years. [0003] The tending methods of lingonberry are still in the preliminary research stage. The existing tending techniques are mostly stubble, light transmission, fire shearing, foliar fertilization, etc. Most of these production-increasing techniques consider the increase in the yield of lingonberr...
