What to do when the fruiting position of Chinese chestnut shifts outward? The latest solution
Chinese chestnut has the habit of bearing fruit on strong shoots, and strong shoots are generally located on the outer periphery of the canopy, so fruiting occurs on the periphery. Young trees have very few fruiting shoots and low yields. As adult trees increase their branching, the branches become progressively thinner and eventually lose the ability to bear fruit. So what should be done when the fruiting position of Chinese chestnut shifts outward? Let's take a look together with the editor.
1. Pruning of fruiting shoots
Based on the characteristic of Chinese chestnut bearing fruit on strong shoots and the positional patterns of strong shoot distribution, attention should be paid to the rational pruning of fruiting shoots and outer branches. Only in this way can the yield of Chinese chestnut be increased. Strengthening the pruning of Chinese chestnut can also effectively prevent the fruiting position from shifting outward. Drawing on cultivation experience from many places, attention should be paid to the heading back of branches, strengthening the protection of mother branches, and effectively cultivating new fruiting shoot groups so that the mother branches become more robust. To improve the uniformity of the fruiting position, the branch-bending method can be used to cultivate new shoots, giving Chinese chestnut the efficiency of three-dimensional fruiting and thereby controlling the outward shift of the fruiting position.
2. Bud removal
Bud removal is also an important measure that can effectively prevent the fruiting position of Chinese chestnut from shifting outward. To improve bud plumpness, the method of removing small buds and keeping large buds should be adopted. Through the pruning of young buds, the young buds maintain good spacing and density, achieving the phenomenon of more buds on the outside and fewer on the inside, concentrating the young buds on strong shoots. This is conducive to the flowering and fruiting of Chinese chestnut and improves the uniformity of fruiting. The male flowers of Chinese chestnut outnumber the female flowers by several times, and to effectively reduce the nutrient consumption of flowers, male flowers should be removed as they grow, maintaining a reasonable inflorescence and achieving the effect of male flowers above and female flowers below, thereby ensuring uniform pollination during the flowering period.
3. Pinching before fruiting
Pinching before fruiting is also one of the important measures to ensure the reasonable growth of Chinese chestnut. It mainly involves keeping only about 4 leaves before fruiting and removing the flower center at the same time. This can significantly increase the fruit-setting rate and reduce the phenomenon of empty burrs. Improving scientific pinching operations and giving play to the advantages of the Chinese chestnut tree species can achieve the effect of improving the quality and yield of Chinese chestnut.
3. Burr thinning
Burr thinning is also an important measure in Chinese chestnut cultivation. Excessive burrs usually affect the overall development of the Chinese chestnut tree. Only by focusing on adopting scientific burr-thinning methods will the growth of the Chinese chestnut tree not be affected.
