1. Do not fertilize at high temperature at noon, the temperature is high at noon, pesticides and fertilizers are easy to volatilize, and betel nut is not easy to absorb, resulting in poor results.
2. Do not use unrotted farm manure, because in the process of re-fermentation of unrotted farm manure, it is easy to produce high temperatures, causing betel nut to burn roots and rot roots, and it is easy to breed diseases and pests.
3. Go to a regular place to buy seedlings, and before you can't be sure whether it is a problem seedling, you can go to the betel nut field to buy seeds and then make a reservation, and finally pick them in person after booking, try to choose old tree seeds that are 15 years old and above, and the best ones that are more than 20 years old are available.
4. Don't overuse nitrogen fertilizer, too much nitrogen fertilizer will easily cause betel nut trees to bear fruit late, and many times it will happen that only the tree grows and does not flower.
5. During the flowering period of betel nut, do not water a lot every day, the water is too sufficient, and it is easy to fall off the flowers.
6. The anti-weed cloth should be used in combination with the actual situation, and the anti-weed cloth should not be abused, as improper use can easily cause insect pests and lead to betel nut rot roots.
7. Fertilization too close to the tree will lead to less absorption of roots, and the worse the effect of triggering fertilizer absorption.
8. The time of autumn fertilizer application should not be too late, if the fertilizer is applied in late autumn, if the temperature drops, the broken root fertilization at this time is not conducive to the healing and growth of the betel nut root system, resulting in slow growth of the tree.
