1 选地、施肥与播种种子田必须选在地势高燥,土壤肥沃的偏酸性地块,最好是未种过瓜的或轮作三年以上地块。种子田必须与周围间隔300m.或周围有天然屏障安全隔离,以免周围其他南瓜屑花粉杂交。加强管理,单收、单打、单藏.为保种子田高产,子粒饱满,必须施足基肥,一般亩施腐熟厩肥2000kg作底肥,追肥用量前轻后重,前期追施氮肥,但不易偏多,以免贪青徒长,秧长瓜小,后期追施磷钾肥料,以促果实肥大,种子饱满,减少秕粒、小粒。播种时种子应去杂去劣,精心选种,提高纯度,去掉秕粒、软皮粒和杂质。重要的是将不符合无杈南瓜种子特性的种去掉。无杈南瓜种子肥大,横径比一般南瓜宽,最大横径可达1.4cm,粒白,千粒重可达35g～400g,是一般农家品种所不及的。 2 田间管理去杂去劣 2.1 间苗、定苗与留苗当瓜苗长到1～2片真叶时要进行间苗、定苗,每埯留一株,每株
An election, fertilization and sowing seed fields must be selected in the high terrain, fertile soil partial acidic plots, preferably not planted melon or rotation of more than three plots. Seed fields must be well separated from the surrounding area by 300 m. Or surrounded by natural barriers to prevent cross-pollination of other pumpkin crumbs. Strengthen the management, single income, singles, single possession .In order to protect the seed field high yield, grain full, must apply the foot base fertilizer, general munsit hedging stable manure 2000kg as base fertilizer, dressing fertilizer before light weight heavy, topdressing nitrogen fertilizer, but not easy to over , So as not to corrupt lengzhang, transplanting long small melons, late phosphate and potassium fertilizer topdressing, in order to promote fruit hypertrophy, full seeds, reduce the tablets, tablets. Seed sowing should go to miscellaneous, bad, carefully selected, improve the purity, remove tablets, soft skin and impurities. It is important to remove non-coniferous pumpkin seed characteristics. No twig pumpkin seed hypertrophy, horizontal than the average pumpkin width, the largest diameter up to 1.4cm, grain white, grain weight up to 35g ~ 400g, is less than the average farmhouse variety. 2 field management to miscellaneous inferior 2.1 Miao, Dingmiao and Miao Miao When the melon seedlings grow to 1 or 2 true leaves to be carried out between the Miao Miao, Dingmiao, leaving a strain of each plant, each strain
