Fertilizer special for masson pine young forest and applying method

Abstract

The invention discloses a fertilizer special for a masson pine young forest. The fertilizer is mainly prepared from, by weight, 20%-30% of organic fertilizer, 60%-75% of macroelement fertilizer, 1.5%-5% of microelement fertilizer, 1% of biological bacterium preparation and 3%-7% of talcum powder, wherein effective ingredients nitrogen, phosphorus and potassium in macroelements account for 15%-20%, and the effective ingredients in microelements account for 1%-3%. Thus, a corresponding fertilizer applying method is further established by an inventor. The fertilizer is suitable for the growth characteristics of masson pines, and is high in utilization rate and good in soil improvement effect, the growth speed of plants is increased, the photosynthesis and disease and pest resisting capacity of the plants are improved, and support is provided for achieving of the target of fast growing and high yield of the masson pine man-made forest. Many years of on-site afforestation experiments indicate that the effect is good, and the fertilizer is suitable for application and popularization.

Description

technical field [0001] The invention belongs to the technical field of plant fertilization, and in particular relates to a special fertilizer for masson pine juvenile stands and an application method. Background technique [0002] Masson pine is the most important fast-growing and high-yielding timber forest tree species in southern China. It has made great contributions to the area of ​​fast-growing and high-yield forests in southern my country, the stock of living trees and timber production. It occupies an important position in the national economy of papermaking, wood processing, forestry and chemical industries . According to statistics, my country has more than 14 million hectares of masson pine forests, accounting for 16.9% of the southern forest stock. However, there are few fast-growing and high-yield forests in masson pine plantations, and the stock volume per unit area is low, which affects the implementation of commercial forest bases in southern my country and t...

AI Technical Summary

Problems solved by technology

As my country's masson pine genetic improvement has entered the second generation to the third generation, the improved varieties produced can basically meet the needs of my country's masson pine afforestation improved varieties, but the level of silviculture is relatively low, which seriously affects the performance of excellent material properties

Researchers in many provinces and regions in my country have also carried out some experimental studies on the fertilization of young Pinus massoniana forests, but they mainly focus on large amounts of elements. In addition, the test period is too short, and the actual application rate of the research results is very low. If used for a long time, it will also cause soil compaction. and degradation

Though, also have the report of individual masson pine special-purpose fertilizer, measure soil and needle leaf growth required nutrient according to the inventor, and masson pine has a large demand for phosphate fertilizer, but not high to the characteristics of nitrogen and potassium fertilizer requirements, these methods cause A lot of waste and residues of fertilizers provide the nutrients needed for the growth of weeds and shrubs, which in turn increases the cost of tending
