Abstract

The invention discloses an experimental method of balanced fertilization of a fir and masson pine seed orchard. According to the flowering and seed setting conditions and fertilizer requirement laws of seed trees of a seed orchard of firs and masson pines in different areas and different generations, and the orchard soil characteristics, a formula fertilization system of the seed orchard of firs and masson pines in different areas and different generations is established by measuring soil, measuring the fruits and leaves of the trees and experimenting the field fertilizer effect, the formula fertilization system includes nutrient diagnosis standard, fertilization amount, fertilization rates, fertilization time and fertilization methods, and the application of the formula fertilization system is demonstrated. The experimental method disclosed by the invention is used for comprehensively understanding macro elements and trace elements of soil, proposing a reasonable fertilization formula suitable for firs and masson pines in different areas and different generations, and determining the soil nutrient content and the needle nutrient concentration of the seed tree with the highest yield by virtue of a mathematic relation of the seed yield per plant and corresponding leaf or fruit nutrient content. The experimental method disclosed by the invention is used for effectively improving the yield and productivity of the seed orchard and remarkably improving economic and social benefits, thereby having broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of plant fertilization, in particular to an experimental method for balanced fertilization in Chinese fir and masson pine seed orchards. Background technique [0002] Strengthening the construction and management of seed orchards is the basis for promoting fast-growing, high-yield, and high-quality trees. Formulated fertilization, also known as balanced fertilization, is the main measure to improve the yield and quality of seed orchards. When the measures such as pruning are in place and the planting density is suitable, rational fertilization often becomes the key external factor to improve the yield and quality of seed gardens. In the mid-1990s, experts in forest breeding and soil fertilizer in my country proposed the main tree species for afforestation. Seed gardens should pay attention to the necessity of formula fertilization in operation and management, but limited by conditions and people’s lack of unde...
