In order to make the majority of jujube farmers to avoid detours while jujube trees are being watered, the author summed up a few watering common sense questions and answers in the form of question and answer, hoping to help the jujube farmer's date production. Jujube flowers should not be watering? 1. What is the basis for watering jujube trees? Is it better to water? Answer: The photosynthesis, transpiration, synthesis, metabolism, and transportation of jujube must have the participation of water. Water is a necessary condition for the growth of jujube trees. It can regulate the temperature of jujube trees to protect them from strong light. Adjusting the ambient temperature and humidity can create favorable conditions for the growth of jujube trees. If the watering is excessive, the soil structure will be destroyed, the nutrient will be lost, the air in the soil will be pushed out, the roots will be affected by the respiration and growth, and the soil salinization will be aggravated (especially in spring). Abnormal tree development, flowering or fruiting, resulting in serious economic losses. Therefore, when watering, it must be done properly and at the right amount. 2. How to implement watering in jujube trees in spring? Answer: The land that is heavily salted in spring should be carefully watered in spring. It is better to wait until the temperature rises to avoid returning alkali, and the better the effect of watering, the better. When the flower is not very dry, try not to water the flower before it is too dry. If it is necessary to water, then a narrow ditch of small water should be used to make the vegetative growth smoothly transformed into reproductive growth, in order to achieve a balanced proportion of nutrient production and reproductive growth, and increase production. 3. What anti-transpiration agents can be used to reduce the watering of spring jujube? Answer: The transpiration agents that can be used for watering or not watering in spring are: 1 Fulvic acid: The effective period is up to 18 days, which can significantly reduce transpiration and increase the water potential, but the leaf temperature is not significantly affected, and the early spraying will be obvious. Improve the water condition of jujube trees. 2 Medical aspirin solution: Dissolve 10 to 15 pieces of medical aspirin with vinegar, and then dilute to 50 to 100 kg for spraying the entire tree. 3 Golden rain anti-drought agent: It can reduce the stomata of leaves and reduce the water transpiration of leaves. 4, jujube flowering should not water? Answer: Watering of jujube trees during flowering should be very careful. If the tree is supplied with too much moisture, the nutrient will overgrow, the flowering phenomenon will occur, the jujube will fall off in a large amount, and the seed setting rate will be reduced; if the weather is very dry, the tree will not receive timely water supply, and it will also appear. Dehydration and dryness affect the fruit setting rate. Pouring or not pouring depends on climatic conditions, precipitation, soil moisture and treatment levels. In the absence of snow in winter, no rain in spring, and dry soil, water should be applied in a suitable manner before flowering. The amount of water can meet the need for flowering and fruit setting, but the amount can not be excessive; if the tree is not water shortage, water conservancy Poor conditions can be used to protect soil, cover grass or spraying transpiration agent, etc., to avoid the drawbacks of inadvertent watering during flowering. 5, how to determine whether the Zaoyuan lack of water? Answer: Whether the jujube garden lacks water depends on the soil moisture content. When the soil moisture content reaches 60% to 80% of the maximum water holding capacity in the field, it is the best condition for the growth and development of the jujube tree. When it exceeds (when the rainfall is too large), it needs to be drained, and when it is low, watering is required. The most simple judging method of jujube farmers: In about 10cm below the surface, take a handful of hands in the soil. If the hands loosen the soil, it is not easy to break, indicating that the soil moisture is more than 50% of the maximum water holding capacity. Water; If the hands are loose and the soil is loose, it means that the soil moisture is too low and needs to be watered; if you hold a block, but two fingers gently pinch and burst, indicating that the water content is poor, it also needs watering. 6. How to water the jujube trees during high temperatures in summer? Answer: When the weather is dry and high temperature, it is necessary to meet the water supply of jujube trees in time. Use small water ground irrigation or barriers, alternate diaphragm watering methods to avoid rapid changes in soil moisture content caused by flood irrigation. Watering time is better in the morning or evening.
