1997～1998年,我们成功地利用黑籽南瓜作砧木进行塑料拱棚西葫芦嫁接栽培。试验结果表明,西葫芦嫁接苗与自根苗相比幼苗耐低温能力强,根系发达,第一雌花着生节位低,最终导致产量增加,尤其是早期产量增加明显。 一、嫁接苗的培育 1.浸种催芽 在保定地区2月初进行,选隔年黑籽南瓜种子,用55～60℃温水浸种15分种后降温到30℃继续浸种6～8小时,浸种期间应多次揉搓黑籽南瓜种皮,祛除粘液以增加种皮透气性,提高发芽势。浸种后
From 1997 to 1998, we succeeded in using black-seed pumpkin as rootstock for plastic arch gourd cultivation. The results showed that compared with the self-rooted seedlings, the seedlings of the zucchini grafted seedlings had the ability of low temperature resistance and developed root system. The first female flowers had lower birth weight and eventually increased the yield, especially the early yield. First, the grafting seedling cultivation 1. Seed germination in Baoding early February, the election of black seed pumpkin seeds every year, with 55 ~ 60 ℃ warm water soaking 15 minutes and then cooled to 30 ℃ soaking 6 to 8 hours, soaking should be more Knead black seed pumpkin seed coat, get rid of mucus to increase the permeability of the seed coat and improve the germination potential. After soaking
