Special control-release fertilizer of sulfur and resin coat for peach and preparation method thereof

Abstract

The invention relates to a special controlled-release fertilizer for sulphur resin coated peaches and a preparation method thereof. The special controlled-release fertilizer for sulphur resin coated peaches is produced with sulphur resin coated urea of different coating volumes, sulphur resin coated compound fertilizer, sulphur resin coated potassium nitrate, potassium sulphate compound fertilizer, etc. The special controlled-release fertilizer for peaches is applied in one go before the budding in spring, thereby reducing the harm of fertilizations to tree roots, and saving manpower and strength. The special controlled-release fertilizer for sulphur resin coated peaches can meet the demand for nitrogen, phosphor, and potassium by peaches in the annual growth period, thereby increasing the production effectively.

Description

technical field [0001] The invention relates to a sulfur-added resin-coated controlled-release fertilizer for peach trees and a preparation method thereof, belonging to the technical field of slow / controlled-release fertilizers. Background technique [0002] Peach trees have been cultivated in my country for more than 2,000 years, and they are mainly distributed in North China, the Yangtze River Basin, and the Yunnan-Guizhou Plateau. In the 1980s, my country began to study the cultivation of peach trees in protected areas. Due to the increase in yield and early listing, the economic benefits have increased significantly, and the cultivation area and area have also expanded rapidly. In recent years, there has been an upsurge in nectarine cultivation. Nectarine is a high-end fruit with good commodity properties and is popular among consumers and producers. Whether it is to satisfy the domestic market or participate in international competition, nectarine has broad development...

AI Technical Summary

Problems solved by technology

At present, the types of fertilizers applied to peach trees include organic fertilizers and chemical fertilizers. Organic fertilizers have long fertilizer effects, but the nutrient content is low and the quantity is limited, which cannot fully meet the needs of high yield; the chemical fertilizers currently applied to peach trees are mainly quick-acting fertilizers, which dissolve quickly in the soil. If too much is applied at one time, it will not only damage the root system, but also cause the loss of nitrogen and potassium fertilizers and the fixation of phosphorus fertilizers by the soil, which will waste fertilizers and reduce the effectiveness of peach trees.

Theoretically, this kind of fertilizer should be fertilized in a small amount and multiple times, but frequent trench digging and fertilization during the growth of peach trees will cut off a large number of roots, which is not conducive to the absorption of nutrients. Labor intensity, increase labor cost

So far, there is no public report on the controlled-release fertilizer for peach trees that can well solve the above problems
