Timely summer clipping of jujube trees is a very happy plant. Poor lighting results in serious consequences of tree growth, fruit drop, and high incidence of diseases and insect pests. 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. Scientific prevention and control of diseases and insect pests August is the peak period of jujube rot, jujube rust, anthracnose, fruit nectar, peach borer, red spider, green-lipped anthrax and date worm. Use triadimefon 800 times solution plus 20% eliminate sweep 1500 times to prevent jujube rust and red spider; jujube rot disease can be used to kill 400 times liquid, copper 400 to 500 times liquid prevention; jujube anthrax can be used anthrax 500 ~ 600 times liquid prevention; jujube fruit shrinking disease can be used on the 1st 600 ~ 800 times liquid control. Zaoyuan pests and red spiders can be used to control 2000 times of wolfberry spirit, 2000 times liquid swabs, avermectin 4000 to 5000 times the liquid to prevent and treat; fruitworm, dates, lepidopteran pests such as Lepidoptera may use diflubenzuron 800 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. Draining drought-proof orchards in orchards are required to repair water gathering facilities such as fish scale pits and reservoirs so as 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. Chlorophyll is one of the most important pigments related to photosynthesis. Photosynthesis is the process of converting light energy into chemical energy by synthesizing a number of organic compounds. Chlorophyll is present in virtually all organisms that can create photosynthesis, including green plants, prokaryotic blue-green algae (cyanobacteria) and eukaryotic algae. Chlorophyll absorbs energy from light, and the energy is then used to convert carbon dioxide into carbohydrates.

The weeds that thrive in weeding and weed growth not only compete with the jujube trees for fertilizer, water, or intermediate host pests and diseases. Therefore, we must timely implement cultivators and herbicides, and we can also use herbicides such as glyphosate and paraquat (these two herbicides are Naturally, we must pay attention not to spray 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 plate planning should be carried out in order to prevent surface compaction, improve soil permeability and maintain soil moisture.
How to control the jujube tree
Reasonable fertilization At the beginning of August, no nitrogen fertilizer was applied to jujube trees with normal growth and normal results. Applying phosphorus and potassic fertilizers as appropriate, the general strain was applied to diammonium phosphate 0.3-0.5 kg. As a result, the weakly growing jujube tree could be applied more properly. At the same time, in combination with spraying, foliar spraying of potassium dihydrogen phosphate, photosynthetic fertilizer or fruit king, Yeba, love more than a multi-element foliar fertilizer 2 or 3 times, in order to promote rapid growth of young fruit.
