Dry mountain area young walnut early-bearing high-yield formula fertilizer and fertilizing method thereof

Abstract

The invention relates to the technical field of fertilizer, in particular to dry mountain area young walnut early-bearing high-yield formula fertilizer and a fertilizing method thereof, which comprise nitrogen, phosphorus, potassium and organic matters proportioning and fertilizing time and method. The dry mountain area young walnut early-bearing high-yield formula fertilizer is particularly suitable for planting young walnut of 8 years or younger. By investigating the current condition of the fertilizing in different production areas of the walnut in the northern-western dry mountain areas, the nutrient characteristics of the walnut garden soil and leaf mineral nutrients of a main production area are determined and analyzed, different fertilizer formulas and fertilizing methods are set in the test, the growth conditions of walnut trees and the yield and the quality of the fruits are investigated and detected. Aiming at the nutrition characteristics of the young walnut tree at different growth and development period, the fertilizer with different formulas is applied to satisfy the nutrients needed by the growth and development of the walnut, the waste of the fertilizer is reduced, the production cost is decreased, the loss of soil nutrient and the pollution of a soil environment are reduced, and a purpose of effectively increasing the yield of the walnut and increasing the income of farmers in the mountain area is achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a formula fertilizer for early fruit and high yield of young walnuts in mountain drylands and a fertilization method thereof. [0002] technical background [0003] Walnut is one of the important woody oil tree species. In recent years, the area of ​​walnut cultivation has expanded rapidly. By 2015, the area of ​​walnuts in Gansu had reached 336,000 hectares, most of which were young walnuts planted after 2006. Walnuts in Gansu Province are mostly planted in mountainous areas without irrigation conditions. The level of walnut management technology is backward, especially the level of walnut nutrition management and fertilization technology is low. The phenomenon of farmers not applying fertilizer or fertilizing blindly is serious, and the utilization rate of fertilizer is low. The benefits are not high. Although different domestic walnut production areas have developed diffe...
