This experiment uses the lower layer of lOcm thick pebbles, the middle layer of 10cm thick furnace ash, the upper layer of 20cm thick pure sand, with 0.300 ^ 0.5% potassium permanganate solution spray disinfection. Intermittent spray equipment is installed so that it can be automatically sprayed as needed to reduce air temperature, maintain leaf wetness, and facilitate rooting. The success or failure of cutting propagation depends not only on the scientific treatment of the cuttings and substrates before cuttings, but also on whether the cutting and cutting methods are reasonable and depends to a great extent on whether the management after cutting is scientific or not. Therefore, the management after cutting is the key to the success of cuttings. The important link. The function of the spray is mainly for the humidity and water supply of the cherry leaves, and the application of the leaf surface humidity sensor for the control of the leaf surface humidity is very common.
Intermittent spray automatic control equipment is based on the change of the intensity and temperature of sunlight and the response of plant cuttings to water demand, and is designed and manufactured by electronic sensors controlled by computers. Therefore, intermittent spray technology is used for tender cutting and seedling raising, in general Under the circumstances, as long as it is not a power outage or the failure of the control part of the leaf surface humidity sensor, the spray equipment will fully comply with the cutting water requirement and automatically control the spray water supply. During the day, the intensity and temperature of the sun sometimes become very high, and the spray equipment will automatically increase the number of sprays to meet the water demand of the plant cuttings at high temperatures, so that one side can ensure stability and no water loss before rooting. One side will not produce water accumulation due to the increase in the number of water sprays. This is because the special structure of the cutting bed removes excess water in a timely manner to ensure that it will not cause rot death due to excessive water spray.
When the intensity of sunshine and temperature drop, the transpiration of the leaves also decreases. The leaf surface humidity sensor automatically controls and reduces the number of sprays. Since there is no photothermal stimulus to the sensor at night, the automatic control function of the controller loses its function and stops than the spray. At this time, the timing spray function of the controller can play a role, and the timing spray is performed according to the set time, generally at night. Can be set to spray once every half hour, such as the night is sunny and no wind, the weather more dew formation, then stop spraying than at night, this time can be used to spray sterilization or leaf fertilization. When stabilizing most of the rooting, the number of sprays should be gradually reduced. If the secondary roots develop in the root system, spray should be stopped. After 3}5 days of hardening, transplanting should be carried out in time.
The use of leaf surface humidity sensors to monitor the leaf surface humidity, the use of all-optical fog cutting seedlings, intermittent spray method to provide water for the cuttings, adjust the temperature and humidity of the plug bed and air, the rooting of the cuttings is beneficial, so that the leaves can Photosynthesis is normally performed to provide necessary auxin and nutrients for rooting of the cuttings, thereby promoting rapid rooting of the cuttings in a well-ventilated, well-drained and clean sterile sand bed, and greatly improving the survival rate of the cuttings.
Application of Leaf Humidity Sensor in Sakura Full Light Spraying Tender Shoot Cutting
The ornamental value of cherry blossoms is very high. In the breeding process, tender cuttings are generally adopted. In order to maintain the excellent traits of the cherry mother, the breeding period is shortened, and the growth rate of the scion and root in the cherry blossom seedling is not uniform. With regard to the problem of foot problems, it is necessary to carry out trials of all-irrigation spray shoot cutting propagation, and it is also of great importance for promotion and application.
