应用“666”药剂进行浇施治螟时,以保持何种深度的田水为宜,各地不一。为此,1957年我们在连作晚稻上进行试验,水稻品种为晚粳猪毛簇,按保持不同田水深度分三个处理:(1)保持1寸田水,(2)保待2寸田水,(3)保持半寸田水,并设一小区不施药作为对照。顺序排列,重复三次,小区长21.4尺,宽7尺,小区面积150平方尺,小区四周筑以高5寸宽6寸的小田埂。试验田于7月27日插秧,行株距7寸见
Application “666 ” Pharmacy when watering borer, in order to maintain what depth of field water is appropriate, varies from place to place. For this reason, in 1957, we conducted experiments on late rice continuous cropping. The rice varieties were late japonica pig tufts, which were divided into three treatments according to different depths of field water: (1) keeping 1-inch water, (2) keeping 2-inch fields Water, (3) keep half an inch of water, and set a plot without spraying as a control. Arranged in sequence, repeated three times, a small area of 21.4 feet, 7 feet wide, residential area of 150 square feet, built around the district to 5 inches wide and 6 inches of Odawara. The experimental field was planted on July 27 and the line distance was 7 inches
