本试验研究了PP_(333) 对马铃薯的喷洒时期及次数。结果表明,喷期在植株大现蕾期产量高,比对照增产27. 02%。不论55ppm 或100ppm,喷一次就足以抑制植株长势。
This experiment studied the spraying date and times of PP_ (333) to potato. 02%. The results show that the spray stage in the plant budding period of high yield, compared with the control yield 27. 02%. Spraying once at 55 ppm or 100 ppm is sufficient to inhibit plant growth.
