辣椒一代杂种已广泛应用于生产,我省一代辣椒生产的全部需种均来源于海南制种。由于海南制种期间热带风暴多,病害重,常造成种子歉收或无收,并因缺乏检疫,引起我省辣椒生产中病害流行,影响产量和品质。另外,随着海南经济开放,价格上涨,每亩辣椒制种成本已由原来的几百元增加到现在的2000多元。单是半年土地租费每亩已高达500多元。鉴此,1990年我们在江西省农科院塑料大棚进行了辣椒制种探索试验。 一、播种育苗 利用电热温床育苗。1989年12月15日播种父本,同年1月4日播种母本。苗期注意肥水管理和炼苗。
Pepper generation hybrids have been widely used in the production of all kinds of pepper production in our province are required species from Hainan seed. Due to many tropical storms during Hainan’s seed production period, heavy diseases often caused poor harvests of seeds or lack of quarantine, causing epidemics of peppers in our province due to lack of quarantine, affecting yield and quality. In addition, with the opening up of Hainan, the price increases, the cost of seed production per mu has increased from a few hundred yuan to more than 2,000 yuan now. The land rent for a single year has been as high as 500 yuan. In view of this, in 1990 we in Jiangxi Province Academy of Agricultural Plastic greenhouse for pepper breeding exploration test. First, sow seedling use electric hotbed nursery. December 15, 1989 planting siblings, January 4 the same year sow mother. Attention seedling fertilizer and water management and hardening.
