土施多效唑对日本栗生长和产量的影响

Effects on the Growth and Production of Japanese Chestnut by PP333 Applied through the Soil

对日本栗进行土施多效唑试验,结果表明:多效唑能明显抑制日本栗结果枝生长量,控制结果枝二次生长,缩短叶片间距,提高果枝粗长比;少量多效唑对日本栗产量及栗果大小并无明显影响;大量土施多效唑剂会导致栗果单粒重减小,严重影响其产量及栗果大小;最理想的土施多效唑量为0.4 g/株。

Applying PP333 througth the soil could significantly inhibit Japanese chestnut fruit branch growth, control fruit branch growth for the second time, shorten the leaves distance, and increase the diameter/length to fruit branch. At the same time, a small amount of PP333 has no apparent impact on the production and the size to Japanese chestnut fruit.
