喷施5种叶面肥对板栗产量和品质的影响

Effects of five foliar fertilizers on yield and quantity of Chinese chestnut

为了研究不同营养元素对板栗产量和品质的影响,以10年生板栗树林为研究对象,就喷施分别含有硫酸镁、硫酸锌、硼砂、硫酸钙等营养元素的叶面肥对板栗产量和品质的影响问题开展了林间小区试验。结果表明:相对于不施叶面肥的对照处理而言,各施肥处理对板栗叶片生长指标、板栗产量和品质指标都有明显的影响;其中,喷施含有硫酸镁的叶面肥对板栗的叶片生长指标和栗实的品质指标的影响最为明显,而喷施含有硼砂的叶面肥对板栗的百粒质量、空苞率等产量指标的影响最为明显。试验结果说明,在基础叶面肥中添加适宜的微量元素对于提高板栗的产量和品质具有促进作用。

To investigate effects of different nutrient elements on yield and quality of Chinese chestnut, taking 10-yearold Chinese chestnut as study object, a field experiment was conducted by five foliar fertilizers of MgSO4, ZnSO4, borax and CaSO4. The results show that leaf growth index, yield index and quality index of chestnut are significantly affected by the foliar fertilizers, compared with CK without fertilizer application. Among all the foliar fertilizer treatments, the one with MgSO~ has the most significant effects on leaf index and quality index. However, and the one with borax had the most significant effects on yield index. The results indicate that quality and yield of chestnut can be improved in some extent by applying foliar fertilizer with suitable nutrient elements.
