Embodiment 1

[0023] The experimental site is located in the vegetable base of the Agricultural College of Guangxi University, and the previous crop was tomato. In order to investigate the biological characteristics of continuous cropping soil, the original tomato field was divided into 6 groups, which were planted with tomato, eggplant, pepper, cucumber, cabbage and green beans. The soil biological characteristics of these 6 groups of test sites are shown in Table 1. It can be seen from Table 1 that the soil microbial biomass, enzyme activity and bacterial diversity of tomato continuous cropping will all decrease. At the same time, it was also found that the biological properties of the rhizosphere soil of tomato bacterial wilt diseased plants deteriorated, and the bacterial diversity decreased (see Table 2).

Embodiment 2

[0039] From April to October 2017, the melon soil improvement test was carried out at the vegetable base of the Agricultural College of Guangxi University. The preparation method of the wood vinegar for improvement was the same as that in Example 1, and the test crop was "Gui Meigua No. 1" melon. The experiment consisted of the following 4 treatments, repeated 3 times: (1) Control group, during the growth period of melon, watering 500 mL of clean water (CK) every 3 days; (2) Watering 500 mL of diluted 300 times of wood vinegar (A); (3) during the melon growth period, water 500 mL of root system every 3 days and dilute 600 times of wood vinegar (B); (4) melon growth period, water 500 mL of root system every 3 days and dilute 900 times times wood vinegar (C). The rest of the field management such as fertilization, weeding, vine introduction, pollination, disease and insect pest control shall be managed according to conventional methods.

Abstract

The invention relates to the technical field of soil improvement, in particular to a method for improving soil by means of wood vinegar. The method for improving the soil by means of the wood vinegarcomprises the following steps: (1) producing the wood vinegar: pyrolyzing biomass under a condition of 200-300 DEG C to obtain a tan stock solution of the wood vinegar, and then diluting the tan stocksolution of the wood vinegar with water; and (2) improving the soil: 5-14 days before soil breaking is conducted, pouring a wood vinegar diluent 50-100 times in volume of the tan stock solution of the wood vinegar, after soil breaking is conducted, pouring a wood vinegar diluent 500-1000 times in volume of the tan stock solution of the wood vinegar, in a seedling stage of plants, spraying a woodvinegar diluent 500 times in volume of the tan stock solution of the wood vinegar, and then spraying a wood vinegar diluent 300 times in volume of the tan stock solution of the wood vinegar two to three times every month. According to the method for improving the soil by means of the wood vinegar, the wood vinegar is produced by adopting weed trees and birch trees, the produced wood vinegar is more reasonable in content of components of organic acids, ketones, phenols and the like, by diluting the wood vinegar into the different multiples of diluents, and applying the diluents with different concentrations for multiple times according to a growth cycle of the plants, not only can the successive cropping obstacle of the crops be overcome, but also bacterial colonies in the soil can be activated, use of chemical pesticides is reduced, an ecological system of the soil is improved, and growth of the crops is promoted.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, in particular to a method for improving soil by using wood vinegar. Background technique [0002] At present, Guangxi is the largest production base of autumn and winter vegetables in my country and the most important vegetable production base of "South Vegetables Transported North". Among them, tomato is the main vegetable variety in Guangxi's autumn and winter vegetable production, and it is also an important vegetable variety in Guangxi's "Transportation of South Vegetables to the North" and "Transportation of Western Vegetables to the East". However, due to the long-term use of a single planting model and the excessive application of chemical fertilizers and pesticides, the decline in soil fertility, bacterial wilt, nematodes and other soil-borne diseases and insect pests and continuous cropping obstacles in Guangxi production areas have become increasingly serious. In addition to t...
