Pomegranate trees are planted in the courtyard, which can beautify the environment as well as eat delicious fruits and cultivate people's sentiments. Doing a good job of management can make the pomegranate tree grow robustly, with large, delicious and colorful fruits.
First, water and fertilizer management
Pomegranate requires a lot of water and fertilizer. If de-fertilization occurs, it will result in reduced production. Therefore, it is necessary to apply fertilizer in a timely and appropriate manner, timely supplement the tree nutrients, and promote fruit enlargement and flower bud differentiation. Fertilization can apply nitrogen, phosphorus, potassium and trace element all-element fertilizer, and organic fertilizer is better. The amount of fertilizers accounts for two-thirds of the whole year, and appropriate amount of water is applied after fertilization. At the same time, foliar spraying fertilizer, spraying 1% urea solution, or 0.3% potassium dihydrogen phosphate solution, or Yongye Lifeline 500 times, the effect will be better.
Second, pest and disease prevention
1. Locusts. To spray 10% imidacloprid 1500 times, or 5% acetamiprid 1500 times, or 50% anti-inverse 1500 times.
2. Red spider. Can be sprayed with 15% lingzhi 1500 times, or 1.8% avermectin 3000-4000 times.
3. Green Blind. Can spray 48% chlorpyrifos 1200 times, or 4.5% beta cypermethrin 1500 times, or 24% methomyl 1000 times.
Third, trim
1. Eradicate the root cause. The pomegranate tree is a multi-main trunk tree. The roots are prone to rooting. The root carp competes with the mother for nutrients, resulting in a decline in the nutrient level of the tree. This is not conducive to the normal growth of the pomegranate tree. The root poop must be removed from the base in time, and do not leave it. Root cause, otherwise it will breed more roots.
2. Pull the branches and open the angle. Pulling branches and falling branches on the prosperous new shoots, the main branches with small opening angles and the upright new ones that grow vigorously can be pulled or hand-rolled into a level or pendulous shape to alleviate vegetative growth and promote flower bud formation.
3. Thinning and improving light. Upright branches, cross branches and overlapping branches were removed from the base to change the ventilation and light transmission conditions. For the main branch that grows too prosperous, you can take the lead and let the weak branches take the lead and balance the tree potential.
new high-performance sensors can effectively detect smouldering fires It can detect all kinds of indoor smoke. When the indoor smoke volume reaches the alarm concentration, the detector will alarm, the red indicator light will be on, and the buzzer will beep, so as to prompt the user to timely check the causes of the leakage accident and eliminate potential safety hazards.
