Cauliflower is a cold-tolerant crop that normally does not receive wind before it is frosted. It minimizes the humidity in the shed and prevents excessive humidity from affecting the growth of broccoli and the breeding of germs. Before the broccoli flower is unnecfted, the temperature in the greenhouse can be appropriately controlled to be a little higher, generally not exceeding 35 degrees; the temperature after the flowering can not be too high, otherwise it may easily cause scattered flowers and flowering branches to affect the taste. The weight of flowers should not exceed 1.5 kilograms, otherwise it is not conducive to sales. When the flower grows to nearly 1.5 kilograms, pay attention to the wind, the general temperature of not less than minus 5 degrees does not close the wind, even if it is lower than the minus 5 degrees, the time to let out the wind will have to lengthen, and it will only get windy after dark. Above 25 degrees, it is difficult to form a flower ball.
In autumn and winter, the overall temperature is relatively low. It is recommended that the farmers have small water and small fertilizers. It is better to keep the soil in semi-humid or slightly dry spots. The lower leaves must be cleaned in a timely manner to increase the ventilation of the lower part and reduce the humidity. The time of watering is recommended to be strong when the sun is sunny in the morning sun and pay attention to the amount of water thick broccoli lodging.
Special reminder: Cauliflower is neither cold nor resistant.
In terms of top dressing, drip irrigation is usually performed by drip irrigation. It is recommended that the drip irrigation be applied twice or three times. Without drip irrigation can be ditching or acupuncture topdressing, usually two can be, it is recommended to use slow-release compound fertilizer, partial potassium nitrogen. Cauliflower prone to calcium deficiency during the flowering period, pay attention to calcium during this period, especially the long-term low temperature and low humidity caused by physiological and calcium deficiency, pay attention to the supplement of trace elements. Appropriate supplements of some boron and zinc help increase crop resistance.
In autumn and winter, the air humidity is relatively large, and germs are easy to breed. The prevention of diseases during this period is very important, especially the occurrence of gray mold and Sclerotinia. The spraying of protective fungicides is regularly carried out, and it is recommended that they be carried out in the morning on a sunny day and sprayed once before the rain. Spraying at the flowering stage pays particular attention, especially triazoles. Http://Content/07c2e2ae-bc7f-44b0-9b05-4ef8bdd2ae07?cType=2
IT02S, is JRT new product in the early 2019, which is a single-point LiDAR sensor, also called tof distance sensor.
