蔬菜种子生长周期长,制种时品种易混杂,引起品种退化,给生产上带来了很多不便,但若注意以下几点,便可以达到快速保纯繁殖。 1.适当早播:作采种用的蔬菜,要适当早播,以达到控制植株生长过快,促进根系发育,使得花枝增多,提高种子产量。 2.控制徒长:采种用的蔬菜必须要求壮苗,应采取各种方法控制徒长。象瓜类、茄果类蔬菜通过多次移植法控制徒长,以壮苗结果,所产种子性状稳定。
Vegetable seeds have a long growth cycle and are prone to be mixed during seed production, causing varieties to degenerate, which brings a lot of inconvenience to production. However, if attention is paid to the following points, rapid pure breeding can be achieved. 1. Appropriate early sowing: vegetables for seed collection, should be appropriate early sowing, in order to achieve control of plant growth too fast and promote root development, making squid increased, increase seed yield. 2 control leggy: seed vegetables used to require strong seedlings, should take various methods to control leggy. Like melons, solanaceous vegetables controlled by many transplant leggy, with strong seedling results, the seed traits stable.
