“七○二”对水稻、蔬莱增产效果显著我队科学实验小组,1971年在区工研所科技人员帮助下,在2.34亩公交12号水稻(插秧)和0.54亩京引39号水稻(卷秧)上进行喷施植物生长刺激素“七○二”试验,于水稻抽穗期喷20度的“七○二”药液一次,扬花期又喷30度的“七○二”药液一次.试验结果,喷药的水稻叶色浓绿、籽粒饱满、成熟早、产量高.公交12号水稻亩产1,200斤,比没处理的单产912斤增产31%;京引39号单产744斤(三类田),比没处理的672斤增产12%.喷药的水稻,千粒重增加,空秕率减 “7092 ” effect on rice, vegetables and fruits significantly increase our team science experiment group, in 1971 in the district with the help of scientific and technological personnel, in 2.34 acres of bus 12 rice (transplanting) and 0.54 acres of Beijing No. 39 Rice seedlings were sprayed with plant growth stimulating hormone test “7092”, spraying 20 degrees at heading stage and “3092” liquid at flowering stage, spraying 30 degrees at flowering stage. The test results showed that the sprayed rice leaf color dark green, full grain, mature early, high yield. Bus 12 rice mu produce 1,200 kg, 912 kg more than the untreated yield increase of 31%; Beijing lead 39 yield 744 kg (three types of fields), 672 kg more than did not handle an increase of 12%. Spraying rice, an increase of 1000 grain weight, empty cut rate
