What to Do About the High Rate of Empty Burrs in Chestnuts? A Detailed Guide to the Latest Reduction Methods
Chestnut is one of the common dried fruits, with a delicious taste. It has high nutritional value and is deeply loved by people, but during the chestnut planting process, the causes of empty burrs seriously affect chestnut yields. So is there a way to reduce the empty burr rate of chestnuts? Below, the editor introduces methods for reducing the empty burr rate of chestnuts for everyone's reference.
1. Choose excellent varieties
The occurrence of empty burrs in chestnuts is inevitably linked to seed selection. If poor varieties or varieties with weak fruiting ability are chosen, it will lead to serious yield reductions in chestnuts. High-quality varieties should be selected, with emphasis on pursuing variety quality, choosing merchants with a good reputation and proper channels, and conducting trials and investigations on the fruit-setting rate of chestnut varieties. Once a variety fails to meet standards, it should be discarded in time to avoid a large number of empty burrs after planting, which would affect chestnut yields. Scientific selection is an effective way to avoid the occurrence of empty burrs in chestnuts, and choosing high-yield, high-quality varieties is an important path to achieving high chestnut yields.
2. Do a good job in soil and fertilizer management
During planting, the soil should be strictly managed. Deep plowing of the soil should be carried out regularly, with rational close planting, a good grasp of row spacing, and increased intertillage and deep plowing, so as to provide sufficient nutrients for the soil and maintain good permeability. Dry grass leaves can also be chosen as mulch, and sufficient farmyard manure should be applied to create a good growing environment for chestnut growth. Covering the tree disc with moved weeds helps maintain moisture and increases the organic matter content in the soil. To keep the weeds from being blown away, a thin layer of soil should be covered over the weeds. To increase yield, intercropping can be adopted by planting other crops among the chestnuts, such as sweet potato and peanut, which can play an excellent role in improving the soil, thereby enhancing soil fertility and increasing the fruit-setting rate.
3. Carry out boron application work
Boron is a key element for chestnut growth, determining chestnut yield and the empty burr phenomenon. A fixed amount of boron should be scientifically applied according to the growth conditions of the chestnuts, soil conditions, and other analyses, to promote chestnut growth and development and avoid the occurrence of empty burrs. The time for boron application should be chosen in April in spring, or in July during the rainy season, and its effects are long-lasting. For boron spraying, foliar fertilizer is chosen, generally in early to mid-May and June, three times a month; after one month of spraying, certain effects can appear and the empty burr phenomenon improves.
4. Strengthen pest and disease control
During the growth, flowering, and fruit-setting process of chestnuts, the occurrence of chestnut pests and diseases is also one of the important causes of empty burrs in chestnuts. If seed selection is poor or the variety has weak disease resistance, pests and diseases will occur frequently, hindering the growth of chestnut trees and preventing normal flowering and fruiting, thus reducing yield. Therefore, before planting, varieties with strong disease resistance should be selected, and during planting, pest and disease control should be strengthened. Once pests or diseases are found, they must be treated promptly.
