The Latest Methods to Improve the Fruit-Setting Rate of Winter Jujube
As summer passes, winter jujube gradually begins to appear in people's view. As one of the more nutritious winter fruits, winter jujube is very good for the human body when eaten regularly, but this year's growers have run into a bit of a problem. The fruit-setting rate of winter jujube is not ideal, so how can it be improved? Come and learn about it together with Qinnong Web below.
1. Moisture control
The growing season of winter jujube is in most cases a relatively dry season, and winter jujube itself has a rather high moisture content, so the importance of water to winter jujube is self-evident. Especially during the pollination period of winter jujube, the requirement for air humidity is very high. If the weather during this period is relatively dry, watering is needed, and spray-style watering should be adopted, spraying the whole tree, so that air humidity can be effectively ensured. The same is true during the fruiting period, when it is only necessary to ensure that the moisture at the roots is sufficient.
2. Light distribution
Many people will say that the factor of light cannot be controlled. What we need to do is only to let the fruiting winter jujube receive light to a greater extent, and this can be achieved manually, which will greatly improve the fruit-setting rate. In places with many fruits and dense leaves, the branches need to be separated so that sunlight can better shine on the winter jujubes hidden inside. For some places with dense leaves and few fruits, they should be pressed toward the inside of the tree, or even fixed in places with less light, and then other places with relatively dense fruits should be covered, increasing the light-receiving area of high-quality winter jujubes and improving the fruit-setting rate.
3. Reasonable fertilization
Fertilization is a threshold that winter jujube cannot avoid. After all, it is very difficult for the soil nutrients of an orchard to ensure a high fruit-setting rate of winter jujube, so fertilizer is the best supplementary means at this time. For the initial base fertilizer, organic fertilizer should be the main part, with compound fertilizer as an auxiliary; during the flowering period, nitrogen fertilizer should be the main part, making the branches and trunk of the winter jujube tree stronger and grow faster, so that the number of flowers will be greatly increased; when the flowering period ends and flowers begin to turn into fruits, potassium fertilizer should be the main part to improve the fruit-setting rate; in the later stage when the fruits begin to grow, potassium fertilizer and phosphate fertilizer should be the main part, together with a small amount of nitrogen fertilizer, so that in terms of fertilizer the fruit-setting rate can be effectively guaranteed.
4. Branch and leaf management
This aspect still has some effect on the fruit-setting rate, but relatively not that much, so everyone can give it a try. This aspect is mainly to reduce the nutrient waste of the winter jujube tree and let the tree's nutrients go to effective places. First, some necrotic branches and leaves should be cleaned up, and some branches and leaves that are in low-sunlight areas but still grow luxuriantly should be partially removed, as the fruit-setting rate in such places will be very low. Second, for some branches and trunks with poor development, directly remove them, so as to provide a better growing environment for other well-growing branches and trunks.
The above are some measures for improving the fruit-setting rate of winter jujube, and these are aspects that are relatively easy for people to control. Winter jujube itself is also considered a relatively easy tree species to grow, and after doing the above measures well, the fruit-setting rate will generally be very good.
