摘　　要：为筛选优化土壤调理剂品种,以不施调理剂为对照(CK),开展3种土壤调理剂(处理1粤田万山土壤调理剂、处理2牡钙酸清土壤调理剂、处理3格林豪斯土壤调理剂)对耕地土壤酸碱度和花椰菜产量品质的影响试验。结果表明:在常规施肥基础上,3个施用土壤调理剂处理的土壤pH平均值分别为5.8、5.6、5.7,较对照(CK)分别增加了18.4%、14.3%、16.3%;3个施用土壤调理剂处理对花椰菜的农艺性状具有改善作用,叶片长宽、球径、单球重、商品性均比对照有不同程度提高,且花椰菜根肿病发病率(3.3%)明显低于对照(CK)(23.3%);处理1和处理3花椰菜折每667 m^2产量分别为1 834.4、1 884.4 kg,分别较对照(CK)增产2.8%和5.6%,但增产效果不显著。试验结果说明不同土壤调理剂能提高土壤pH值、改善花椰菜农艺性状、提高花椰菜对根肿病的抗性,土壤调理剂对提高花椰菜的产量也有一定的促进作用。In order to select and optimize the varieties of soil conditioner,by taking the treatment with no conditioner as the control group(CK),the experiment was carried out on the effect of three kinds of soil conditioner(treatment 1 with Yuetianwanshan,treatment 2 with Mugaisuanqing,and treatment 3 with Greenhouse)on the pH value of soil in cultivated land and the yield and quality of cauliflower.The results showed that:on the basis of conventional fertilization,the average pH value of soil under the treatments with the three soil conditioners was respectively 5.8,5.6 and 5.7,which respectively increased by 18.4%,14.3%and 16.3%compared with the control group.The three treatments with soil conditioner had an improvement effect on the agronomic characters of cauliflowers.The leaf length&width,bulb diameter,single head weight and commercial properties were all increased to different degrees compared with the control group.Furthermore,the incidence rate of clubroot disease of cauliflowers(3.3%)was significantly lower than that of CK(23.3%).The yields of treatment 1 and treatment 3 were respectively 1 834.4 kg and 1 884.4 kg per 667 m^2,which increased by 2.8%and 5.6%compared with CK,but the yield-increasing effect was not significant.The results showed that different soil conditioners could improve the pH value of soil,the agronomic characters of cauliflowers and the resistance to clubroot disease of cauliflowers,meanwhile,there was also a certain promoting effect of soil conditioner on the yield of cauliflowers.
