Embodiment 1

[0049] In this embodiment, a 10-year-old octagonal tree is the object of implementation of the planting method for increasing the yield of octagonal based on the balance of soil nutrients.

[0050] In October 2015, a 10-year-old octagonal tree was selected for sampling survey in a planting base in Wuzhou City. Each group set up 3 repeated experiments, and each survey sample (20m×20m) was used to measure the trees in the sample plot with a ruler and an altimeter. Choose a standard tree for the diameter and height of the tree, choose a standard tree, then fell it, and then according to the Monsic layered cutting method, every 2m as a section, apply the tree nutrition method, according to the roots, trunks, branches, leaves, flowers and Weigh the fresh weight of each organ of the whole tree, and take a small amount of representative samples according to each organ, weigh the fresh weight, bring it back to the room, dry it in an oven to a constant weight, and then weigh the dry weight...

Embodiment 2

[0081] In this embodiment, a 13-year-old octagonal tree is the object of implementation of the planting method for increasing the yield of octagonal based on the balance of soil nutrients.

[0082] In October 2015, a 13-year-old octagonal tree was selected for sampling survey in a planting base in Wuzhou City. Each group set up 3 repeated experiments, and each survey plot (20m×20m) was used to measure the trees in the plot with a ruler and an altimeter Choose a standard tree for the diameter and height of the tree, choose a standard tree, then fell it, and then according to the Monsic layered cutting method, every 2m as a section, apply the tree nutrition method, according to the roots, trunks, branches, leaves, flowers and Weigh the fresh weight of each organ of the whole tree, and take a small amount of representative samples according to each organ, weigh the fresh weight, bring it back to the room, dry it in an oven to a constant weight, and then weigh the dry weight to calcul...

Embodiment 3

[0113] In this embodiment, the 15-year-old octagonal tree is the object of implementation of the planting method for increasing the yield of the octagon based on the balance of soil nutrients.

[0114] In October 2015, 15-year-old octagonal trees were selected for sampling survey in a planting base in Wuzhou City. Each group set up 3 repeated experiments, and each survey sample (20m×20m) was used to measure the trees in the sample plot with a ruler and an altimeter. Choose a standard tree with the diameter at breast height and height of the tree, and then fell it, and then cut it according to the Monsic layered cutting method, each 2m as a section, apply the whole tree nutrition method, according to the roots, trunks, branches, leaves, flowers and Weigh the fresh weight of each organ of the whole tree, and take a small amount of representative samples according to each organ, weigh the fresh weight, bring it back to the room, dry it in an oven to a constant weight, and then weigh ...

Abstract

The invention provides a planting method for increasing yield of Illicium verum based on soil nutrient balance. Regionalization is performed according to tree species planting areas and soil types, asoil sample is collected to investigate the content of soil available nutrients, soil bulk density and root distribution, and the supply amount of the soil available nutrients including nitrogen, phosphorus and potassium is determined through the following formula. According to the fertilizer, biomass of organs such as roots, trunks, branches, leaves, flowers and fruits of Illicium verum trees andcontent of nitrogen, phosphorus and potassium in each organ are analyzed precisely by sampling according to nutrition absorption and utilization characteristics of the Illicium verum trees and a forest all-tree nutrition method for soil, so that absorption and accumulation absolute values and relative proportion of macroelements such as nitrogen, phosphorus and potassium in the threes are calculated scientifically, accordingly, the scientific proportion of macroelements (N, P and K) of nutrient fertilizer for fertilization of the Illicium verum is calculated, and the yield is increased by 25%or higher on average.

Description

Technical field [0001] The present invention relates to the field of agricultural planting, in particular to a planting method for increasing the yield of star anise based on soil nutrient balance. Background technique [0002] For a long time, the people in the octagonal producing areas have fairly extensive management of Illicium Oerum. Too many anises are in the wild or semi-wild state, and the yield is low. In recent years, as the price of star anise has risen, the public has gradually increased their awareness of the management of star anise tending and fertilization, especially the investment in star anise fertilization. However, due to the lack of understanding of the growth and development of star anise and its fertilization characteristics, they prefer to apply nitrogen fertilizer. Light application of phosphorus and potassium fertilizers, and the selection of fertilizer varieties, application amount, fertilization time, and application methods are not well mastered. The...
