板栗栽培历史悠久,是重要的出口物资之一。为尽快改变目前平均株产不足2kg的低产局面,于1989～1990年进行板栗施肥、修剪和去雄等诸方面的试验研究,以谋求为其增产提供必要数据和具体方法。一、材料与方法该研究是在河南新县5个乡镇进行,均采用单因子试验,试材是板栗嫁接树,品种为二板栗,其立地条件为梯田,土壤肥力较低,未行间作。为确保试验的准确
Chestnut cultivation has a long history and is one of the important export materials. In order to change the present low yield situation with an average yield of less than 2 kg per plant, pilot studies on chestnut fertilization, pruning and dehumanization were conducted in 1989-1990 in order to provide the necessary data and specific methods for increasing production. I. Materials and Methods The study was conducted in five townships in Xinxian County of Henan Province. Single factor experiments were conducted. The test materials were chestnut grafted trees with two varieties of chestnut. The site conditions were terraced fields with low soil fertility and no intercropping. To ensure the accuracy of the test
