Sugarcane smut resistance determination method based on internet-of-things system

Abstract

The invention discloses a sugarcane smut resistance determination method based on an internet-of-things system. The determination method comprises the following steps: black powdery spores of smut whips are collected from sugarcane seedlings; the spores are prepared into spore suspension liquid, then sugarcane seed stems are placed in the spore suspension liquid to be soaked, the sugarcane seed stems are taken out to preserve moisture and accelerate germination, the sugarcane subjected to accelerating germination is planted in a plastic basin containing a substrate, and an internet-of-things system is installed; and the internet-of-things system monitors the whole process from sugarcane planting to disease resistance determination, starts investigation from the occurrence of a first smut plant, and records the number of smut plants. According to the sugarcane smut resistance determination method based on the internet-of-things system, environmental factors in the sugarcane growth process are visually monitored, sugarcane is accurately managed, the sugarcane germination rate is high, operability is high, the accuracy of sugarcane smut resistance determination is enhanced, the sugarcane smut resistance can be accurately reflected, the disease resistance determination efficiency is improved, technical support is provided for sugarcane disease-resistant breeding, and the method is of great significance in accelerating the disease-resistant breeding process.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for measuring sugarcane smut resistance based on an Internet of Things system. Background technique [0002] Sugarcane smut (Sugarcane smut) is an important sugarcane disease. Sugarcane smut was first reported in Natal, South Africa in 1877, and then the disease spread to countries in the eastern and western hemispheres. In my country, sugarcane smut was reported in Guangzhou sugarcane area in 1932, and then Guangxi, Yunnan, Fujian, Taiwan, Hainan and other provinces successively reported the occurrence of the disease. The occurrence of sugarcane smut was reported successively in the United States and Australia, and it spread rapidly and became the main sugarcane disease. So far, sugarcane smut has become a common sugarcane disease in various sugarcane producing areas in the world. The average incidence rate is 18%, and the incidence rate of ratoon cane is as hig...

Problems solved by technology

[0005] At present, the test of sugarcane smut resistance mainly adopts indoor artificial inoculation to test the disease resistance. It can be carried out in the open air or in a greenhouse, and the soil or sand and sugarcane are used for potting. The soil and sand are relatively heavy. For example, a large number of sugarcane varieties are tested for disease resistance. , it is time-consuming and labor-intensive; in addition, most of the disease resistance testing time is selected to be tested in March-April. At this time, the temperature is relatively low and is not suitable for the invasion of smut, resulting in a low incidence rate, and the incidence of susceptible varieties is not obvious, so it cannot be accurately evaluated. Sugarcane disease resistance; in addition, there is no auxiliary management of the Internet of Things system, and water and fertilizer management is not timely, resulting in low seedling emergence rate and irregular seedling emergence; even in greenhouses, due to high temperature, seedlings will be burned, which will affect the determination of sugarcane disease resistance , leading to inaccurate evaluation of sugarcane disease resistance
