Barrenness mountainous region Chinese chestnut plantation method

Abstract

The invention relates to a barrenness mountainous region Chinese chestnut plantation method comprising the following steps: digging colonization pits with relatively big density in the hillside one year in advance; filling the colonization pits with turf soil, leaves from the hillside and night soil; mixing in slaked lime if the soil is acidic, mixing in ferrous sulphate if the soil is slightly alkaline, and the slaked lime and ferrous sulphate can keep the soil PH value to be 5-6; using overlay film fermentation to enable the soil in the colonization pit to be rich in sapling growth nutrition; applying phosphorus-containing fertilizer in sapling plantation; slightly lifting the sapling, so the root can fully contact with the fill soil, and the fill soil is higher than the ground so as to reserve water. The fill soil covers the ground so as to reduce ground temperature, and can be deeply plowed into the soil after rotting; two times of foliar fertilizer and additional fertilizer can greatly improve sapling survival rate; an insecticidal lamp around the sapling can control insects so as to greatly reduce pesticide quantity; tests show that the survival rate can be above 98%, and average mu yield in 6 years can improve by 10%.

Description

technical field [0001] The invention belongs to the technical field of chestnut planting, in particular to a method for planting chestnuts in barren mountainous areas. Background technique [0002] Chestnut, also known as chestnut and Chinese chestnut, is a plant of the genus Chestnut in the Fagaceae family.

Problems solved by technology

Chestnut grows fast and is easy to manage. It is suitable for planting in mountainous areas. However, in some barren mountainous areas, the survival rate of planting is very low. The main reasons include: 1. The seedlings are weak. Although the price is cheap, it is difficult to survive after planting; 2. Mountainous areas The soil layer is thin, and the pits are shallow when planting, which is not conducive to the development of the root system; 3. Fertilizer and water are not applied according to the growth law, resulting in weak tree vigor; 4. The pH of the soil does not meet the growth needs of the saplings
