What to do about low fruit set in bayberry? These methods help you improve fruit set
Bayberry is sweet and sour and is welcomed by many people, and its nutritional value is very high. In addition, bayberry juice, bayberry wine and other products derived from bayberry are very popular on the market. Therefore, the planting area of bayberry is now growing larger and larger, and when fruit growers plant bayberry, the first issue is how to improve the fruit set rate. So what exactly should be done? Below, the editor will briefly introduce this to everyone. Let's take a look together!
1. Scientific fertilization
Fertilization is a key measure for providing sufficient nutrients to bayberry. We should not only apply enough base fertilizer before planting, but also topdress appropriately according to the growth condition of the bayberry tree. When topdressing, pay attention to controlling the fertilization position and the nutrient ratio in the fertilizer. While ensuring sufficient nitrogen, phosphorus, potassium and other nutrients, also pay attention to supplementing an appropriate amount of trace elements to ensure that the nutrient needs of bayberry growth are met. Moreover, the fertilization method should be reasonably adjusted according to the growth stage of bayberry, because the fertilizer requirements of bayberry differ at different stages, so everyone must pay close attention.
2. Fruit tree management
When planting bayberry, an excellent management method is the key to determining the fruit set rate of bayberry. Therefore, when planting, management work must be done well, fertilization and watering amounts must be controlled, and intertillage and weeding must be done well. In particular, pruning work must be done well, and the pruning method should be reasonably adjusted according to the growth condition of the bayberry. Open up the canopy of the bayberry tree and improve the airiness and light penetration of the bayberry tree. Only by pruning some overly long, overly dense, crossing and overlapping branches can the fruit set rate of the bayberry tree be effectively improved, thereby further increasing yield and expanding planting benefits.
3. Reasonable flower promotion
For bayberry trees more than five years old, carry out flower promotion work by appropriately applying soil fertilizer or spraying foliar fertilizers such as paclobutrazol. Note that bayberry trees under five years old and weak in growth must not be treated. When applying paclobutrazol to the soil, the time is generally from October to March. First scrape away the surface soil of the bayberry tree, then sprinkle the paclobutrazol into the tree basin, and then cover with soil. When applying foliar fertilizer, for vigorous trees that have not yet set fruit, spray when the spring and summer shoots have grown about 5 cm.
4. Pollination and fruit retention
In order to improve the fruit set rate of bayberry, we spray gibberellin once during the full flowering period of the bayberry tree or after the flowers fade, which can significantly improve the fruit set rate of bayberry. And because the bayberry tree is a crop that requires cross-pollination between different plants, if the ratio of male and female trees in the orchard is imbalanced, or if the number of male trees is insufficient, then on sunny and cloudy days, appropriately prune some full-bloom male branches and hang them on the female trees. Finally, we must also do a good job in fruit retention. Some varieties have serious fruit drop before mature harvest, so 2-3 weeks before harvest, spray some fruit-drop prevention agent, which can effectively reduce the fruit drop phenomenon.
The above is a brief introduction to how to improve the fruit set rate of bayberry. The fruit set rate of bayberry is directly related to yield, so we must pay attention to doing management work well to protect our planting benefits. That is all for today's introduction.
