Jujube tree summer management measures
May and June are the period of jujube tree germination, leaf expansion, new shoot growth and flowering and fruit setting. In this period, in order to improve fruit setting rate and high quality fruit rate, the following management measures should be taken. 1. Branch opening angle. Through the measures of pulling branches, supporting branches, hanging branches, and other branches, the branches are opened at an angle to achieve the purpose of tree ventilation and light transmission, and uniform and reasonable distribution of branches and leaves. 2. Wipe buds and topping. Spread the buds of the jujube heads emitted from the inner crown of the tree crown in time; re-center the jujube heads at the base of the jujube heads with no growth space from the jujube stock; remove 8 or less jujube heads from the entire tree Apart from topping, all the rest are topping. 3. Fertilize before flowering. If no fertilizer has been applied since the fruit was harvested last year, the trees in the full fruit period will be applied in the hole method, applying 15-20 kg of urea and 30-40 kg of potassium sulfate per mu, and watering after fertilization. In early July, grown-up trees were given 0.5 to 1 kg of ammonium bicarbonate and 2 to 3 kg of superphosphate. Jujube trees need sufficient water during the growth period, especially during the flowering and fruit development period, and must be filled with water. It is worth noting that watering at the flowering stage should not be too large, so that the water content of the root distribution layer should reach 70% of the field water holding capacity. In dry years, the method of diligent watering can be used, and the effect is also very good. 4. Improve fruit setting rate during flowering. Through the foliar spraying of urea, boron, clear water, spray 920, painting to promote the king of flowers, topping and other measures to improve fruit setting rate. 5. Paddle hoe. Jujube gardens after raining and watering should be hoeed in time to remove weeds and help to protect the soil. 6. Spray medicine. In mid-to-late June, spray 800 times the solution of Cocklebur and add 25% Fenrusting 1500 times solution 1-2 times to prevent and control tortoise worm, jujube armyworm and jujube rust.
