板栗(Castanea mollissima Bl.)是国内外市场很受欢迎的农产品。安徽是全国板栗重点产区之一。实地调查发现:我省板栗单产低的直接原因之一是雌花太少而雄花太多。这种现象与水土流失和土壤贫瘠有密切关系。许多研究者指出~([1,2,6-9]),高等植物的性别表现易受外源激素和外界条件的影响。为了准确地掌握外源激素和肥料的使用时期,应当查明试验地区板栗生殖器官的发育分化阶段及其物候期。因此我们研究了植物激素和氮素对板栗性别表现的影响,目的在于增加雌花、减少雄花和提高板栗的产量和品质。
Chestnut (Castanea mollissima Bl.) Is a popular agricultural products in domestic and foreign markets. Anhui is one of the key producing areas in China. Field survey found that: One of the direct causes of the low chestnut yield in our province is too little female flower and too much male flower. This phenomenon is closely related to soil erosion and poor soil. Many researchers point out that ([1,2,6-9]), the gender performance of higher plants is susceptible to exogenous hormones and external conditions. In order to accurately grasp the use of exogenous hormones and fertilizers, the development and differentiation stages of chestnut reproductive organs and their phenophase should be identified. Therefore, we studied the effects of plant hormones and nitrogen on chestnut sex performance with the purpose of increasing female flowers, reducing male flowers and increasing the yield and quality of chestnuts.
