近两年来,我区经小区试验和大面积示范证明,水稻喷洒米醋,方法简便、成本低、增产显著。水稻喷洒米醋有增根、增蘖、增粒重和提高结实率等作用。在水稻分蘖始期,每亩喷洒3两米醋(加水90斤),5天后调查表明,喷洒米醋的比未喷的平均每株多3.7条次生根,每亩平均增加分蘖1.65万株。各时期喷洒米醋的23个对比试验中,平均千粒重25.8克,比对照多0.4克。结实率平均为91.3％,比对照高0.7％,单产比对照高11.5％。
In the past two years, our district has been experimentally plotted and plotted on a large area to prove that spraying rice vinegar with rice is simple, low in cost and significant in yield increase. Spraying rice vinegar has increased root, tillering, grain weight and improve seed setting rate and so on. At the beginning of rice tillering period, 3m 2 vinegar (90kg water) was sprayed per acre. After 5 days, the survey showed that the average number of secondary roots sprayed with rice vinegar was 3.7, and the average number of tillers was 16,500 per mu. In 23 comparative trials spraying vinegar during each period, the average grain weight was 25.8 grams, 0.4 grams more than the control. The average seed setting rate was 91.3%, 0.7% higher than the control and the yield was 11.5% higher than the control.
