Since the beginning of summer, after a period of high temperature and drought in the previous period, a rainy season across the province on July 18 made our province really enter the hot and humid season. With the advent of the rainy season, how should the jujube tree be managed at this time? What are the major tasks? It has become a topic of concern for the majority of jujube farmers. Discuss the management of jujube seedlings and the outcome period separately. First, pay attention to the management of seedlings to promote strong Zhuang seedlings sown this year, jujube seedlings, hot and humid season is the fastest growing season. Due to the drought during the previous period, the seedlings grew slowly. Therefore, we should seize the favorable conditions of high temperature, high humidity, and rapid growth of seedlings at this stage, and apply urea 1-2 times in a timely manner. The interval should be 20 days or so. The amount of mu should be 7-10 kg to promote the growth of seedlings. At the same time, timely cultivating and weeding will create a good environment for the growth of seedlings. In the prevention of pests and diseases, attention should be paid to the control of red spider and jujube mycelia. The choice of 2% abamectin 4000-5000 times, 20% exfoliation 1500-2500 times, and 10% ciprofloxacin 2000-3000 times . Rootstock nursery disease is not serious, but it does not need to control. For plants that grow rapidly and reach a height of 60 cm or more, they can gently pick their hearts to promote bold growth. The growth of seedlings cultivated in the past year is relatively prosperous. Generally, no nitrogen topdressing is applied after August, and potassium dihydrogen phosphate can be topdressed in each spraying of pests and pests, and the spraying concentration is 0.2-0.3%. Seedling heights of 1-1.2 meters after moderate topping to promote bold growth. Second, the results of the meticulous management of the output to the province's jujube cultivation, jujube is mainly distributed in the Taihang Mountain area in the west of Fuping, line Tang, Zanhuang, Neiqiu, Wuan line, Jinsi jujube is mainly distributed in Pizhou, Ganzhou In Xianxian, Qingxian and other counties, fresh food species are mainly distributed in Huanghua, Yanshan, Fucheng and Gaochun counties. The rainy season is also an important period for jujube management. According to the experience of previous years, jujube trees in the result period should do the following: 1. Reasonable fertilization: At the beginning of August, no nitrogen fertilizer was applied to jujube trees with normal growth and normal results. Ammonium 0.3-0.5 kg, the result of many, weakly growing jujube trees can be applied more properly. Compared with jujube trees of other species, winter date should be slightly larger. At the same time, the combination of spraying of potassium dihydrogen phosphate, photosynthetic fertilizer or fruit king, leaf tyrants, love and other multi-element foliar fertilizer spraying 2-3 times to promote rapid growth of young fruit. 2, timely summer cut: jujube trees are very happy plants, poor light will cause the tree body lengthy, fruit drop, serious consequences of high pest and disease. In mid-August, we must promptly eliminate dense branches, leggy branches, branches of diseases and insects, and weak branches. Except for those who bear the responsibility of expanding the crown, all of them should be properly picked to improve the light conditions and nutrient distribution of the tree and promote fruit growth. Accelerate growth. 3. Scientific prevention and control of diseases and insect pests: The high temperature and humid weather create favorable conditions for the occurrence of a variety of diseases and insect pests. In August, it was jujube rot, jujube rust, anthracnose, fruit disease, peach borer, red spider, and green-lover stink bug. During the peak period of the damage of Ziziphus orientalis, it is necessary to adopt the triadimefon 800 times solution plus 20% eliminate sweeping 1500 times to prevent the date rust and red spiders against the different major pests and diseases; jujube rot disease can be used to kill 400 times liquid, king Copper 400-500 times liquid prevention and treatment; jujube anthracnose can be used to control anthrax 500-600 times; jujube fruit shrinkage can be used on the 1st fruit 600-800 times the liquid, agricultural streptomycin 100-140 international units / ml, agricultural Oxytetracycline 200 IU/ml control. The red spider in the jujube garden can be used to control the 2000 times solution of peony, 2000 times solution of sweeping and 4000-5000 times of avermectin, and can be used for the lepidopteran insect pests such as fruitworm and jujube. Times of liquid, Peach Xiaoling 2000 times, 2000-3000 times of kung fu baby control. Adding the spreading agent in the medicament, such as ripping, cellulose, soybean milk, etc., can effectively improve the control effect. For Jinsi jujube and other heavier fruit drop varieties, spray 30ppm Zaofengling No. 2 at the beginning of August and Zaofengling No. 2 at 20ppm at the end of August or 15ppm, 7- After 10 days, 20ppm and 15ppm in the first half of the month were effective for preventing pre-harvest fruit drop. 4, weeding and weeding: weeds growing vigorously, not only with the jujube tree competition for fertilizer, water, or the middle host of pests and diseases, so we must timely cultivator weeding, we can also use glyphosate, paraquat and other herbicides (these two weeding The agent is inactivated, so be careful not to spray it on the jujube tree). The weeds removed can be overturned with green manure or covered with tree trays. After the rain, timely cultivator or tree tray planning should be conducted to prevent surface compaction, improve soil permeability and maintain soil moisture. 5. Drainage and Drought Control: Most of the rainfall in our province is concentrated in the rainy season. The orchards in the mountains must have water collection facilities such as fish scale pits and reservoirs in order to accumulate rainwater and prevent autumn drought. The jujube gardens in the plain area must be dredged from the Zaoyuan drainage ditch and encounter continuous rainfall, so that the accumulated water can be removed in time to prevent guilt.
