中国板栗品质优良,适应性广,抗病性强,在世界上独树一帜。湖北省罗田、麻城、京山、巴东等县,有大面积板栗园,是全国板栗重点产区之一。但由于经营水平低,管理粗放,树体营养水平不高,造成板栗雌花少,落花落果严重,空苞多,出实率低,严重影响了单位面积产量,远远不能满足国内外市场的迫切需求。为此,对中国林科院林研所经济林室开发的MN制剂进行了试验,以探讨MN制剂对板栗结果与生长的影响,为提高板栗的单位面积产量和品质提供依据。1 材料与方法1.1 试验地点与试材
Chinese chestnut quality, wide adaptability, disease resistance, unique in the world. Hubei Province, Luotian, Macheng, Jingshan, Patong and other counties, a large area chestnut garden, is one of the key producing areas of chestnut. However, due to the low management level and extensive management, the nutrition level of tree body is not high, causing less chestnut female flowers and falling flowers, more empty bract and lower real rate, seriously affecting the yield per unit area and far from meeting the needs of domestic and foreign markets demand. Therefore, the MN preparation developed by Lin Institute of Forest Research Institute of Chinese Academy of Forestry was tested in order to explore the effect of MN preparation on the results and growth of chestnut, and to provide basis for improving the yield and quality per unit area of Chinese chestnut. 1 Materials and Methods 1.1 Test sites and test materials
