板栗由于推广了良种,产量逐年提高,小面积的丰产典型不断出现。但也出现了空棚多,结实率降低的问题,影响产量继续上升。因而对板栗成棚的研究,减少空棚,提高结实率是当前迫切需要解决的生产问题。自1979年,我们以金丰为主要试验试材,从品种、浇水、疏棚和授粉等几方面试验研究 Chestnut as a result of the promotion of improved varieties, production increased year by year, a small area of ​​typical high-yield continue to emerge. However, the problem of more sheds and lower seed setting also appeared, affecting the output to continue to rise. Therefore, shedding the chestnut research, reducing the empty shed, improve the seed setting rate is an urgent need to address the current production problems. Since 1979, we take Jinfeng as the main test material, from the aspects of variety, watering, shed and pollination
