Embodiment 1

[0038] A kind of indoor cultivation rice growth test screens the method for suitable biochar type, and this method comprises the steps:

[0039] S1: Select five rice beds with the same area indoors, sprinkle biochar No.1, biochar No. In different rice beds with the same area, and marked with signs;

[0040] S2: Mix the sprinkled biochar and the surface soil of the five rice beds evenly, transplant the rice seedlings respectively, and insert the seedlings of the same species. The five rice beds have the same amount of rice transplanted. After 15 days of inserting the seedlings, start monitoring the five rice beds. Rice plant height, monitor the rice plant height of five rice beds once every 6 days, monitor 5 times continuously, calculate the average rice plant height corresponding to each monitoring time through the data processing system, and draw the The average rice plant height standard curve of each rice bed; the ordinate of the average rice plant height standard curve is...

Embodiment 2

[0046] A method for indoor cultivation rice growth test screening suitable biochar type, the method comprises the steps of:

[0047] S1: Select five rice beds with the same area indoors, and sprinkle biochar No. 1, biochar No. In different rice beds with the same area, and marked with signs;

[0048] S2: Mix the sprinkled biochar and the surface soil of the five rice beds evenly, transplant the seedlings respectively, and insert the seedlings of the same variety, the five rice beds have the same amount of rice transplanted, and 18 days after inserting the seedlings, start monitoring the five rice beds. Rice plant height, monitor the rice plant height of five rice beds once every 6 days, monitor 5 times continuously, calculate the average rice plant height corresponding to each monitoring time through the data processing system, and draw the The average rice plant height standard curve of each rice bed; the ordinate of the average rice plant height standard curve is the averag...

Embodiment 3

[0055] A method for indoor cultivation rice growth test screening suitable biochar type, the method comprises the steps of:

[0056] S1: Select five rice beds with the same area in the room, and sprinkle biochar No. 1, biochar No. In different rice beds with the same area, and marked with signs;

[0057] S2: Mix the sprinkled biochar and the surface soil of the five rice beds evenly, transplant the seedlings respectively, and insert the seedlings of the same species. The five rice beds have the same amount of rice transplanted. After inserting the seedlings for 20 days, start monitoring the five rice beds. Rice plant height, monitor the rice plant height of five rice beds once every 6 days, monitor 5 times continuously, calculate the average rice plant height corresponding to each monitoring time through the data processing system, and draw the The average rice plant height standard curve of each rice bed; the ordinate of the average rice plant height standard curve is the av...

Abstract

The invention provides a method for screening a proper charcoal type for indoor rice cultivation growth testing. According to the method, processing and statistics are carried out on al rice data in an average rice plant height standard curve, an average rice spike length standard curve, an average effective standard spike and plant number curve, and an average rice filled grain number standard curve at each rice bed and thus an applicability standard curve is drawn. The method can be operated simply. Compared with other methods, the method enables the cost to be reduced by more than 12%. Moreover, the period of the method is short; the efficiency is higher than the efficiency of other methods by more than 19%; the obtain data have small errors; the rice growth situations of all rice beds can be monitored in real time; and the manpower and materials are saved substantially.

Description

technical field [0001] The invention relates to a screening method, in particular to a method, a data processing system and a biochar compound for screening a suitable biochar type in an indoor cultivation rice growth test. Background technique [0002] With the rapid growth of population, the rapid development of industry, the per capita arable land has been decreasing, and the shortage of food and feed has become increasingly prominent. This will be a global challenge faced by mankind in the 21st century. 2 The rate of decline will decrease, and the area of ​​cultivated land will be lower and lower than the survival base line planned by the state. [0003] Biochar is a solid product produced by high temperature pyrolysis of biological organic materials (biomass) in an anoxic or anaerobic environment. It can be used not only as a high-quality energy source and soil improver, but also as a reducing agent, fertilizer slow-release carrier and carbon dioxide sequestration agen...
