摘  要:
试验发现0.3%壳聚糖水剂对番茄品质和产量的提高有明显的促进作用,其中500倍液可使单果重增加11.1%,产量提高21.7%。同时它可以明显提高番茄对病害的抵抗能力,抑制病害发生,且3次施药效果更佳,500倍液第3次施药后对番茄晚疫病防效达到74.0%,300倍液对绵疫病可达78.2%。300~500倍液壳聚糖对2种病害的防效与50%多菌灵600倍液防效相近。

摘  要:
chitosan could improve the quality and the yield of tomato. Its 1/500 dilution could increased the weight of per fruit by 11.1% and the yield by 21.7%. It could also improve the resistance to various diseases. After applying 3 times, 1/500 dilutions efficacy against Phytophthora infestans was 74.0%, 1/300 dilutions efficacy against Phytophthora parasitica dast was 78.2%. 1/300-1/500 chitosan has the similar effect controlling above two diseases to 1/600 carbendazin.
