    摘要:

    通过2年田间试验,研究不同用量硅钙钾镁土壤调理剂对马铃薯产量及经济效益的影响。选取2个试验点,每个试验点均设置6个处理,分别为CK(不施氮)、C(单施土壤调理剂)、FU(习惯施肥)、FC1(习惯施肥+600/300 kg·hm-2土壤调理剂)、FC2(习惯施肥+900/600 kg·hm-2土壤调理剂)、FC3(习惯施肥+

    Abstract:

    Two years of field experiments were conducted to study the effects of different amounts of Si-Ca-K-Mg soil conditioner on potato yield and economic benefits.This test took two sites and both were set up six treatments:CK(no nitrogen),C(single soil conditioner),FU(habitual fertilizer),FC1(fertilizer + application of 600/300 kg·hm-2 soil conditioner),FC2(fertilizer + application of 900/600 kg·hm-2 soil conditioner),FC3(fertilizer + application of 1200/900 kg·hm-2 soil conditioner).The results showed that,(1)Compared with the FU treatment,after the application of sulphur-calcium-potassium-magnesium soil conditioner,Potato yield and commodity rate increased by 11.9%~21.1% and 14.1%~20.9% respectively in 2018. In 2019,potato yield under FC2 treatment also increased significantly,while commercial potato yield did not change significantly.(2)The nitrogen content of plants of FC3 and potassium content of tubers of FC1 and FC3 significantly increased in 2018.In 2019,nitrogen content in tubers of FC1 and FC3 treatments significantly increased.In addition,in 2019,application of sulphur-calcium-potassium-magnesium soil conditioner inhibited the uptake of phosphorus by tubers.(3)The nitrogen utilization rate of sulphur-calcium-potassium-magnesium soil conditioner treatments increased by 5.0%~11.9%,and nitrogen agronomic efficiency increased by 14.7~26.0 kg·kg-1 in 2018. In 2019,nitrogen utilization rate increased by 4.4%~14.9% and nitrogen agronomic efficiency increased by 4.4~35.3 kg·kg-1.(4)In 2018,the output value of sulphur-calcium-potassium-magnesium soil conditioner treatments increased by 5256.41~7230.77 yuan·hm-2,and the income increased by 3456.41~4830.77 yuan·hm-2;In 2019,its output value increased by 1862.87~10060.43 yuan·hm-2;Revenue increased by 1262.87~8860.43 yuan·hm-2. It can be concluded that promoting nutrient absorption and improving nitrogen use efficiency are the important reasons for potato yield increase,and potato yield is correlated with the application amount sulphur-calcium-potassium-magnesium soil conditioner.The optimal application amount of sulphur-calcium-potassium-magnesium soil conditioner in local potato fields is recommended to be 600 kg·hm-2.
