玉米制种施用ABT_4号生根粉可使制种产量增加14.8%,促进地下根系的生长发育,提高抗灾能力;施用ABT_4号的投入产出比为1:5.7,是一项提高玉米制种产量、增加经济收入的有效途径之一。 1 材料及方法 1.1 玉米制种组合为412×78-84-7Ht。 1.2 将ABT_4号粉剂先用酒精溶解,然后加水稀释成10ppm溶液浸泡412和78-84-7Htl小时,捞出阴干后播种。对照是以清水浸泡412和78-84-7Ht相同时间,捞出阴干后播种。 1.3 田间设计:处理与对照顺序排列,不设重复,播种面积各20亩,父本与母本行比为1:6,播种密度为4.2万株/公顷。
The ABT-4 rooting powder could increase the yield of seed production by 14.8%, promote the growth and development of underground roots and improve the ability of resisting disaster. The input-output ratio of ABT-4 was 1: 5.7, One of the effective ways to increase economic income. 1 Materials and methods 1.1 Seed combination of corn for the 412 × 78-84-7Ht. 1.2 The ABT_4 powder first dissolved with alcohol, and then diluted with water to 10ppm solution soak 412 and 78-84-7Htl hours, remove and dry after sowing. The control is soaked in water for 412 and 78-84-7Ht the same time, remove and dry after sowing. 1.3 Field design: treatment and control sequence, without duplication, sowing area of 20 acres, the ratio of male and female line 1: 6, planting density of 42000 plants / hectare.
