A field humidifying device for inducing wheat scab and its application method

Abstract

The invention relates to a field humidifying device for inducing wheat scab and its use method, which includes a time control device; the time control device includes a power input terminal, a pipeline pump control terminal and more than one solenoid valve control terminal; The power input end is connected to the external power supply end, the control end of the pipeline pump is connected to the driving end of the pipeline pump, the water inlet end of the pipeline pump is connected to an external water source, and the water outlet end of the pipeline pump is connected to the water inlet end of more than one main pipe. The solenoid valve connected to the control end of the solenoid valve, the water outlet of each main pipe is located in the experimental field where wheat scab needs to be induced, each auxiliary pipe is set on the side of the car, and the water outlet of each main pipe is connected to the side of the auxiliary pipe. At the water inlet end, the tail of each auxiliary pipe is sealed, and each auxiliary pipe is vertically connected with several capillary pipes at intervals, and the top of each capillary pipe is connected with a nozzle. The invention can not only provide higher wheat spike environmental humidity for the onset of wheat scab, effectively reduce the influence of environment on wheat scab resistance identification, but also effectively save manpower and labor.

Description

technical field [0001] The invention relates to the field of research on wheat scab, in particular to a field humidifying device for inducing wheat scab and a method for using the same. Background technique [0002] Wheat is one of the important guarantees of world food security, meeting one-fifth of human caloric needs. Wheat scab, caused by Fusarium graminearum and other Fusarium species, is a widespread worldwide disease that mainly occurs in warm and humid wheat growing areas. Among them, the winter wheat area in the middle and lower reaches of the Yangtze River and the spring wheat area in Northeast my country are frequent and recurrent areas of scab in China. With global warming, changes in farming systems and farming methods, wheat scab is spreading to the Huanghuai wheat region, northern wheat region, southwest wheat region and northwest wheat region. The occurrence of head blight will cause different degrees of yield reduction, and will damage the quality of wheat...

AI Technical Summary

Problems solved by technology

Although this method can maintain humidity to a certain extent, it has the following disadvantages: (1) Bagging will not only increase the temperature in the bag, but excessive temperature will adversely affect the development of wheat spikes, and sometimes even cause males Sterility, reduced seed setting rate, affect the test, and the change of the temperature in the bag will affect the occurrence of scab, and then interfere with the test results

(2) The humidity in the bag comes from the water lost by the transpiration of the ears of wheat, but scab inoculation needs to be carried out when the wheat is flowering, and the flowering period of different varieties / lines is different, and different varieties / lines need to be inoculated at different times Bagging, and the soil humidity will vary greatly at different times, so the amount of water lost by transpiration of the ears of wheat will be different, and the humidity in each bag cannot be guaranteed to be consistent.

(3) Bagging not only requires a lot of manpower input, but the operation is more cumbersome, and sometimes the bag is blown off by the wind, which affects the test

Although this method can keep the humidity of the ears of wheat, it takes a lot of time to wrap the moisturizing cloth on the outer periphery of the ear layer after spray inoculation in this method, and the preparation of the moisturizing cloth needs to spend a lot of manpower and material resources. , and highly specialized, it is difficult for skilled workers without professional training to complete the work
