牡蛎壳土壤调理剂对春桃番茄产量与品质的改善效果

以牡蛎壳土壤调理剂作为实验材料,研究不同施用量的牡蛎壳土壤调理剂对春桃番茄土壤养分及作物产量、品质的影响.实验设置0 kg/hm2(对照组CK)、1500 kg/hm2(T1组)、2250 kg/hm2(T2组)、3000 kg/hm2(T3组)4个施用量水平.田间实验表明:在春桃番茄的整个生长周期,随着牡蛎壳土壤调理...

Effect of Oyster Shell Soil Conditioner on the Production and Quality of 'Chuntao' Tomato

Field experiments were carried out to study the effects of different application amounts of oyster shell soil conditioner on soil and crop yield and the quality of ‘Chuntao’ tomato.Four application rates were set including 0 kg/hm2 (control CK),1 500 kg/hm2 (T1),2 250 kg/hm2 (T2) and 3 000 kg/hm2 (T3).During the whole growth period of ‘Chuntao’ tomato,with the increasing addition of oyster shell soil conditioner,increment of soil pH value,soil exchangeable calcium and organic matter content were detected.At the same time,with the increasing of the application amounts of oyster shell soil conditioner,the individual fruit weight,total output per unit area,the content of vitamin C,juice yield of the fruit were on the rise.Through the analysis of ripe fruit,with the increasing of the application amounts of oyster shell soil conditioner,the individual fruit weight,total output per unit area,the content of vitamin C and juice yield of the fruit were on the rise.Analyzing of ripe fruit,T3 group revealed the highest single fruit weight and juice yield,which increased by 8.39% and 11.61%,respectively as compared with the CK group.T1 group had the highest total output per unit area and vitamin C content as its yield increased by 26.66%,and the vitamin C content increased by 24.75%.Therefore,application of oyster shell soil conditioner can neutralize acidic soil,increase the acid base buffering capacity of the soil,and improve the individual weight,production,vitamin C content and juice yield of ‘Chuntao’ tomato.
