草本植物一般是用幼苗进行嫁接的,这要有一定的技术,接合部分須結扎,操作也比較麻煩。怎样改进呢?一般嫁接的原則是,接穗的叶片要少,而且小,并适当控制溫度,以减少水分蒸发,这样才能提高成活率。在这个原則的指导下,江西安义中学生物教研組的同志們对这問題进行了实驗研究,創造了一种种子嫁接法,并首先在瓜类作物上試驗成功。具体方法是:把葫芦种子用溫水浸一天,播种在花盆里作为砧木(或露地育苗移栽在花盆里)。在砧木播种的第3-4天,将西瓜种子同样用溫水浸一天, Herbs are generally grafted with seedlings, which requires a certain amount of technology, the joints must be ligated, and the operation is also troublesome. How to improve? The general principle of grafting is that the scion blades should be small and small, and the temperature should be properly controlled to reduce the evaporation of water, so as to increase the survival rate. Under the guidance of this principle, the comrades of the Jiangxi Anyi High School Biology Teaching and Research Group conducted an experimental study on this issue and created a method of seed grafting, which was first tested successfully on melon crops. The specific method is: soak the seeds of the gourd with warm water for one day and sow seeds in the pots as the rootstock (or transplant the seedlings in open pots in pots). On the 3-4th day after sowing the rootstock, the watermelon seeds were also soaked in warm water for one day.
