板栗是我省的重要干果果树,具有果粮兼用的双重用途,是著名的“铁杆粮食作物”。我省寻甸、禄劝、富民、武定等县产的板栗,具有粒大、壳亮、肉细、味香的优点,是国际市场上享有盛誉的出口商品。但由于长期管理粗放,品种单一,土壤硼素不足,造成结蓬少,空蓬多,产量极低,平均株产仅2—3公斤,最高株产也只10余公斤。若要改变现状,须采取以下措施。一、加强栽培管理。我省多数板栗产区,都是采取“只收果,不管树”的放任经营,形成缺株多,树势弱,树形紊乱,通风透光不良,病虫严重,不能发挥结果潜力。因此,应加强常规的土肥水管理、整形修剪和病虫防治,以复壮树势,为提高产量打 Chestnut is an important dried fruit tree in our province, with dual purposes of fruit and grain, is the famous “hardcore food crops.” In our province, Xundian, Luquan, Fumin, Wuding and other county chestnuts, with large grain, shell bright, meaty, delicious taste of the advantages of the international market is a prestigious export commodities. However, due to the long-term management of extensive, single species, lack of soil boron, resulting in less knot, empty Peng, low yield, the average strain of only 2-3 kg, the highest strain of only 10 kg. To change the status quo, we must take the following measures. First, to strengthen cultivation and management. Most of the chestnut producing areas in our province adopt the strategy of “only harvesting fruits regardless of tree”, resulting in the lack of trees, weak trees, disorderly trees, poor ventilation and light, serious pests and diseases and the inability to realize the results. Therefore, we should strengthen the conventional soil and fertilizer management, plastic trimming and pest control to rejuvenate the tree vigor, in order to increase production hit
