Abstract
The invention discloses a method for improving bamboo forest soil in different coverage cultivation years. The method can realize effective recovery of ecological functions of heat preservation, water retention, ventilation and the like of the bamboo forest soil in different coverage cultivation ages, and has the effect of green sustainability.
Description
The invention relates to a soil improvement method, in particular to a method for improving bamboo forest soil with different coverage cultivation ages.
Background
Bamboo shoots are important output products of bamboo forests, account for a large proportion in the bamboo industry output value, and particularly create greater economic benefits with the application of efficient forcing culture technologies such as bamboo forest coverage and the like. The covering cultivation is a process of changing the growth phenological period of the bamboo forest by utilizing the artificial control of factors such as facility conditions, ecological factors and the like to realize the out-of-season germination of the bamboo shoots. However, after the bamboo forest is covered for a long time, soil acidification becomes a serious ecological consequence, which causes the obvious changes of the physical and chemical properties and the nutritional structure of the soil and the obvious changes of the microbial composition of the soil. At present, the method of adding quicklime (CaO) into a covering bamboo forest is mainly adopted to solve the problem of soil acidification; by applying the bamboo forest biological organic fertilizer, the soil nutrition is increased and the microbial community structure is adjusted. However, the problems of poor heat preservation, water holding, ventilation effect and the like of the soil for covering and cultivating the bamboo forest cannot be avoided.
Disclosure of Invention
The invention aims to provide a method for improving bamboo forest soil with different coverage cultivation ages. The method can realize effective recovery of ecological functions of heat preservation, water retention, ventilation and the like of different degenerated bamboo forest soil, and has the effect of green sustainability.
The technical scheme of the invention is as follows: a method for improving the soil of bamboo forest in different covering and cultivating years includes such steps as applying the bamboo charcoal particles with different sizes in different covering and cultivating years, and proportionally mixing them together.
The method for improving the soil of the bamboo forest in different covering cultivation years specifically comprises the following steps:
a. selecting bamboo charcoal particles with corresponding particle sizes according to the coverage cultivation age of the bamboo forest;
b. applying bamboo charcoal particles in 10-11 months per year;
c. the bamboo charcoal particles are buried deeply in the soil.
According to the method for improving the bamboo forest soil in different covering cultivation years, the bamboo charcoal particles with the particle size of 0.10-1.00 cm are applied.
According to the method for improving the bamboo forest soil in different covering cultivation years, the application amount of the bamboo charcoal particles is 200-300 kg/mu, and the application amount of the bamboo charcoal particles is correspondingly increased when the covering cultivation period of the bamboo forest is longer.
According to the method for improving the bamboo forest soil in different covering cultivation years, the bamboo charcoal particles are uniformly applied in a spreading mode, and then the bamboo charcoal particles are deeply buried in a soil layer of 15-25 cm in length.
According to the method for improving the bamboo forest soil in different covering cultivation ages, bamboo charcoal particles are deeply buried for seedling raising, hole sowing is used for seedling raising, after hole sowing, fine soil is burnt by fire for covering seeds until seeds are not seen, then the effective amount of 2,4-D butyl ester per mu is 50g, water is uniformly sprayed on a bed surface for 40kg, soil treatment is carried out, grass covering and water sprinkling are carried out for weeding, and the bamboo seedlings are formed by sprouting and soil emergence in succession after 15-20 days.
Compared with the prior art, the bamboo charcoal particles with corresponding particle sizes are applied to the bamboo forest soil with different coverage cultivation ages, the bamboo forest soil with longer coverage cultivation ages is applied with larger bamboo charcoal particles, and the bamboo charcoal particles are pertinently selected for improvement according to the coverage cultivation ages. The bamboo charcoal particles are hexagonal in molecular structure, hard in texture, fine, porous, strong in adsorption force, high in porosity, suitable for being used as carriers of soil microorganisms and organic nutritional ingredients, capable of enhancing soil activity, good in soil improvement material, capable of achieving effective recovery of ecological functions of bamboo forest soil such as heat preservation, water retention and ventilation, and green and sustainable in effect. In addition, the bamboo charcoal particles have alkalescence and adsorbability, and can reduce or relieve acidification of bamboo forest soil to a certain extent and adsorb heavy metals in the soil. And the raw materials of the bamboo charcoal particles are derived from bamboo, so that the bamboo charcoal particles are green and cyclic, low in cost, convenient to implement and suitable for large-area popularization. In addition, the seedling raising is carried out in the bamboo forest after the bamboo charcoal particles are implemented, the seedling raising effect is good, the survival rate is high, and the seedlings are robust.
Detailed Description
The present invention is further illustrated by the following examples, which are not to be construed as limiting the invention.
Example 1: in a phyllostachys edulis forest with the accumulated coverage cultivation age of 4 years, bamboo charcoal particles with the particle size of 0.30cm are uniformly spread according to the application amount of 200 kg/mu before the bamboo forest in 11 months in 2017, and the bamboo charcoal is buried deeply by turning soil. Finishing the bamboo forest coverage in 12 middle of the month. In 2018, in 3 last ten days, the soil temperature of a soil layer (a main distribution area of bamboo rhizome roots) of the bamboo forest is improved by 1.0 ℃ compared with the soil temperature of the bamboo forest which is not applied with the same soil layer of bamboo charcoal particles and has the same coverage age; the water content of soil with a soil layer of 20cm to which the bamboo charcoal particles are applied is improved by 10 percent compared with the water content of soil without the bamboo charcoal particles; the carbon flux of the soil with the bamboo charcoal particles is improved by 1.5 mu mol.m compared with the carbon flux of the soil without the bamboo charcoal particles-2·s-1。
Example 2: in a phyllostachys edulis forest with the accumulated coverage cultivation age of 8 years, bamboo charcoal particles with the particle size of 0.50cm are uniformly spread according to the application amount of 250 kg/mu before the bamboo forest in 11 months in 2017, and the bamboo charcoal particles are buried deeply by turning soil. Finishing the bamboo forest coverage in 12 middle of the month. In 2018, in 3 last ten days, the soil temperature of a soil layer (a main distribution area of bamboo rhizome roots) of the bamboo forest is improved by 1.0 ℃ compared with the soil temperature of the bamboo forest which is not applied with the same soil layer of bamboo charcoal particles and has the same coverage age; the water content of soil of a soil layer with 20cm added with the bamboo charcoal particles is improved by 8 percent compared with the water content of soil without the bamboo charcoal particles; the carbon flux of the soil with the bamboo charcoal particles is improved by 1.0 mu mol.m compared with the carbon flux of the soil without the bamboo charcoal particles-2·s-1。
