Problems solved by technology

The application of chemical fertilizers has greatly improved the yield of vegetables and crops on limited land, but it has also brought many problems such as land compaction, soil fertility failure, and water pollution. Although genetic variation, such as transgenic or hybrid technology, can improve Biomass, but the safety uncertainty of genetically modified food makes people have doubts about genetically modified vegetables; while hybrid technology is currently widely used in rice planting, and the mature promotion and application of other crops or vegetables is less
[0004] For a long time, most of the landscaping plant wastes have been landfilled with domestic garbage, or undergo extensive treatment such as natural stacking and incineration, which has caused global warming, aggravated urban smog, and land resource pollution.

Embodiment 1

[0028] A soil improvement material component for increasing vegetable biomass, made of biochar and compost;

[0029] Biochar is made from camphor branches in Hangzhou Botanical Garden, which are then calcined and carbonized at low temperature in an anoxic environment. In the carbonization machine, the temperature was raised to 40°C at 1°C / min and kept for 24 hours to make the water migration uniform, and then nitrogen gas was introduced at a flow rate of 5mL / min, and then the temperature was raised to 400°C for low-temperature calcination and carbonization for 12 hours;

[0030] The compost is made by crushing the branches of trees and shrubs to less than 2cm by a pulverizer as compost and urea. In a cement tank that is sealed on all sides, with an opening on the top surface and one side elevation, the length of the cement tank is 1.5m, the width is 1.2m, and the height is 1.3m; then add 0.1% of the mass of the fermentation base material. Microbial agent, and control the humi...

Embodiment 2

[0033] A soil improvement material component for increasing vegetable biomass, made of biochar and compost;

[0034] Biochar is made from broken camphor branches in Hangzhou Botanical Garden and then calcined and carbonized in an anoxic environment. The preparation process is as follows:

[0035]Cinnamomum camphora branches are crushed to a length of less than 2cm by a crusher, ventilated and dried to a water content of 60%, placed in a carbonization machine and heated to 60°C at 2°C / min for 12 hours to make the water migration uniform, and then passed into Nitrogen, the flow rate is 3mL / min, and then the temperature is raised to 500°C for low-temperature calcination and carbonization for 5 hours;

[0036] The compost is made from the branches of trees and shrubs as compost and fermented with urea. The preparation process is as follows:

[0037] Mix the pile material and urea according to the ratio of C / N ratio of 20:1 to obtain the fermentation base material, place it in the...

Embodiment 3

[0040] A soil improvement material component for increasing vegetable biomass, made of biochar and compost;

[0041] Biochar is made from broken camphor branches in Hangzhou Botanical Garden and then calcined and carbonized in an anoxic environment. The preparation process is as follows:

[0042] Cinnamomum camphora branches are crushed by a crusher to a length of less than 2cm, ventilated and dried to a water content of 65%, placed in a carbonization machine at 1°C / min and raised to 40°C for 24 hours to make the water migration uniform, and then nitrogen gas is introduced at a flow rate of at 4mL / min, then heat up to 450°C for low-temperature calcination and carbonization for 8 hours;

[0043] The compost is made from the branches of trees and shrubs as compost and fermented with urea. The preparation process is as follows:

[0044] Mix the stockpile and urea according to the ratio of C / N ratio of 30:1 to obtain the fermentation base material, place it in the cement tank, th...

Abstract

The invention relates to the technical field of vegetable planting, discloses a soil improvement material component for improving vegetable biomass, and aims to break through the current situation that vegetable biomass is improved through chemical fertilizer application or genetic change. The soil improvement material component comprises biochar and compost according to a mass ratio of the biochar to the compost of 1:0.3-2, wherein the biochar is prepared by crushing garden plant branches and calcining the crushed branches at a low temperature in an anoxic environment, the garden plant branches are soaked in a sodium bicarbonate solution before preparation, and the compost is prepared by mixing branches of arbors and shrubs as a compost material with nitrogen, stacking and fermenting. Thesoil improvement material component provided by the invention can effectively improve the vegetable biomass and reasonably utilize garden plant wastes.

Description

technical field [0001] The invention relates to the technical field of vegetable planting, in particular to a soil improvement material component for increasing vegetable biomass. Background technique [0002] Biomass, also known as plant mass, refers to the total weight of organic matter stored in plants, generally expressed in dry weight. The larger the biomass, the higher the organic matter content in the plant. With the improvement of people's living standards, the demand for vegetable consumption is increasing. Increasing the biomass of vegetables to increase the proportion of edible parts of vegetables is of great significance for meeting people's needs. [0003] At present, the biomass of vegetables or the amount of plants can be increased by applying high-efficiency chemical fertilizers or from the perspective of genetic variation. The application of chemical fertilizers has greatly improved the yield of vegetables and crops on limited land, but it has also brought...
