1 使用多效唑可培育多蘖壮秧,增强抗逆性1.1 多效唑浸种用15%多效唑可湿性粉剂0.1g 对水1L。按该浓度的溶液1.0~1.5kg 浸泡种子1.0kg 进行浸种,浸种时间为36h。可使父、母本的秧苗变矮,单株分蘖数提高,绿色叶片数增多,叶色深绿,白根数增多;抗逆性增强。1.2 多效唑拌芽谷当父、母本催芽后,用15%多效唑可湿性粉剂0.3g对水1 kg,按此浓度拌芽谷。可使父、母本的秧苗素质提高,单株分蘖数增加,白根数增多;抗逆性增强。1.3 喷施多效唑在父、母本处于一叶一心时,将秧田厢面上的水排干或母本直播田厢面上的水排干,使厢面上无积水,旌用15%多效唑可湿性粉剂600~750g/hm~2对水喷施,或在父、母本处于三叶一心时,施用15%多效唑可湿性粉剂1200~1500g/hm~2对水喷施。可使单株分蘖数增加,父、母本的秧苗植株变矮,白根数增多;增强抗逆性。
1 paclobutrazol can be used to cultivate more tiller seedlings, and enhance the resistance 1.1 paclobutrazol soaking with 15% paclobutrazol WP 0.1g water 1L. According to the concentration of the solution 1.0 ~ 1.5kg soaking seeds 1.0kg soaking, soaking time 36h. Can make the parent and the female parent seedling shorter, the number of tillers per plant increased, the number of green leaves increased, dark green leaves, white root number increased; resistance increased. 1.2 paclobutrazol mixed bud when the father and mother germination, with 15% paclobutrazol WP 0.3g water 1 kg, according to the concentration of mixed bud Valley. Can make the parent and the female seedlings improve the quality of seedlings, tillers per plant increased, white root number increased; increased resistance. 1.3 spraying paclobutrazol in the parent and the mother in a leaf one heart, the water on the surface of the tank field drained or maternal live Tian Fang surface drained water, so that there is no water on the box surface, with 15% paclobutrazol Wettable powder 600 ~ 750g / hm ~ 2 sprayed on water, or in the parent and the mother in the clover heart, the application of 15% paclobutrazol WP 1200 ~ 1500g / hm ~ 2 spraying on water. Can increase the number of tillers per plant, the father, mother plant seedlings shorter, white root number increased; increased resistance.
