How to water apricot trees after sitting fruit?

How to water apricot trees after sitting fruit? What is there to pay attention to? Please introduce apricot fruit watering can refer to the following methods: first, fruit expansion period irrigation apricot tree after fruit setting, fruit growth in the early stage, depending on soil moisture irrigation, soil is not very dry irrigation. Excessive soil moisture can easily cause new shoots to grow, aggravate the nutritional competition between shoot leaves and fruit, cause serious physiological fruit drop, and affect fruit development. After physiological fruit drop, a small amount of water can be irrigated once in the hard core stage, that is, the early stage of the second rapid expansion to promote the growth of the fruit. 2. Irrigation 2-3 weeks before fruit harvest. This irrigation can promote fruit expansion and increase yield, but attention should be paid to irrigation methods, otherwise it is easy to cause fruit cracking and reduce fruit commodity quality. 3. Irrigation precautions if the soil is dry, the following points should be paid attention to when irrigation is really needed: ① irrigation should be carried out in combination with soil topdressing. To change the irrigation method, do not flood irrigation, should adopt micro-irrigation, such as drip irrigation, hole irrigation, seepage irrigation, plastic film irrigation and so on. The amount of ② irrigation. Do not flood irrigation, should be small water irrigation frequently, irrigation volume should be small, not large, it is better to irrigate several times. ③ irrigation time. Irrigation should be carried out on a sunny morning or in the morning to avoid watering in the afternoon or evening to prevent fruit cracking. It is best to do it in the morning, when the greenhouse temperature, ground temperature and water temperature are relatively close. After the root absorbs water, the transpiration of the tree increases gradually with the increase of light and room temperature, which can maintain the water balance of various organs and make the peel, pulp and kernel expand synchronously to avoid the occurrence of cracking or peeling phenomenon. ④ water temperature. It is better to use deep well water or preheated water. The temperature of deep well water is generally 13-15 ℃, which is very close to the mild ground temperature of the greenhouse in the morning. ⑤ loosens the soil and preserves soil moisture. During the whole growing season of apricot trees, especially after irrigation, it is necessary to hoe and loosen the soil in time to preserve soil moisture, increase soil permeability, reduce soil water evaporation, reduce air humidity in greenhouse, and promote high-quality fruit production.
