楸树播种苗当年移栽试验研究

Experimental Study on Transplanting Catalpa bungei Seedlings in the Seeding Year

楸树原产我国,材貌双全,俗称“木王”。随着推广与研究的深入,新优品种相继出现,播种当年的移栽方式、栽植时间与新优品种初期选择的准确性直接相关。本文对楸树移栽的各变量因素(移栽方式、移栽后是否浇水、遮光率等)进行初步研究。结果表明,楸树移栽方式是带土球移栽加85%遮光率为最优;栽植月份以5月移栽为佳;移栽后要适时浇水。

Catalpa bungei is indigenous in China commonly known as“Timber King”for its high-quality timber and graceful structure.New fine cultivars of the species have been developed with the deepening of promotion and study.Ways and time of transplanting the seedlings in the seeding year are directly related with the accuracy of initial selection of new fine cultivars.In this paper,a preliminary study was made on the variable factors(including transplanting way,watering or no watering after transplantation,shading rate)in transplanting the seedlings.The results showed that ball transplanting and 85%shading is the optimal,the best transplanting time is May and timely watering is necessary for the transplanted seedlings.
