为了解决红小豆生产中徒长、倒伏、产量低而不稳等问题。于1986～1987年在冀红小豆一号现蕾盛期,喷施B_9植物生长调节剂。喷后叶色变深,株高变矮,单株粒重、百粒重增高,成熟期提早,增产效果明显。一、喷施B_9植物生长调节剂对冀红小豆一号农艺性状的影响在冀红小豆一号现蕾盛期,每亩喷施2500～5000ppmB_9水溶液75公斤,株高明显降低.比对照(喷施清水)矮31.2～40.4cm。分枝变化不明显:单株结荚数,除5000ppm处理的比对照低3.1个外,其它处理均高于对照2.2～16.9个。单株粒重,除5000ppm处理的比对照低3.2克外,其它处理均高于对照0.8～4.1克。百粒重略有增加,一般增高0.1～1.4克。据1987年结
In order to solve the problem of growth, lodging, low yield and instability in the production of red bean. In 1986 to 1987 in the Jidong adzuki bean squall peak, spraying B_9 plant growth regulators. After spraying, the leaf color became darker and the plant height became shorter. The grain weight per plant and the weight of 100 grains increased, the maturity was earlier and the yield was obviously improved. First, spraying B_9 plant growth regulator on Jidong adzuki bean agronomic traits in Jidong adzuki bean squall peak, sprayed 2500 ~ 5000ppmB_9 per acre 75 kg of water solution, plant height was significantly lower than the control (spray Shi water) short 31.2 ~ 40.4cm. Branches change insignificantly: The number of pods per plant, except for 5000ppm treatment 3.1 lower than the control, the other treatments were higher than the control 2.2 ~ 16.9. The grain weight per plant was higher than that of the control by 0.8-4.1g except for the treatment of 5000ppm lower than the control by 3.2g. A slight increase in 100 tablets, generally increased 0.1 to 1.4 grams. According to 1987 knot
