July (small summer to great heat). At this time, it is the expansion period of the navel orange fruit and the growth period of the late summer. It is important to focus on the following tasks:
Shi Zhuang fruit fertilizer. The result tree was planted with fruit fertilizer from late June to early July, and was applied before the onset of drought. The fruit can be fertilized, and the amount of fertilizer should be determined by the amount of results and the tree potential. The results are many, the tree is weak, and the results are small, and the tree is weak.
Timely drought resistance. It is prone to drought in high temperature in summer. When the curl of the tree leaves cannot be restored in the evening, the water should be poured (poured) in time. The irrigation (pouring) water in high temperature and drought should avoid the high temperature period of 12~17 hours. In order to reduce the fruit cracking from August to September, a new high-fat film can be sprayed to strengthen the peel toughness.
Wipe the branches. For the growing fruit trees, the spraying of the flower king 3 forced the toppings to have a large amount of nutrient return, and the inertial advantage of the tip quickly weakened to the topping situation. Early autumn shoots at the end of July or at the end of the month, the best time to shoot is after the rain.
Pest Control. The result tree focuses on the prevention and control of rust tick. When the individual fruit of the orchard is covered with ash, it should be sprayed. The available agents are: 73% acetylene (Keite, 螨 )) emulsifiable concentrate 2500 times liquid or 0.5% bitter smoke agent (fruit saint) 1500 times liquid and with the new high-fat film 500 times liquid can also be added to the foliar fertilizer to increase efficiency.
