Effect of potassium-calcium-magnesium nitrate compound fertilizer on yield and economic benefit of cucumber and tomato in greenhouse
Taking cucumber and tomato as research objects,the yield and income increasing effects of potassium-calcium-magnesium nitrate compound fertilizer are studied.The results show that the yields of cucumber and tomato are increased significantly,and the cucumber is put on the market one week earlier than that of farmer fertilization treatment,when potassium-calcium-magnesium nitrate compound fertilizer is applied with irrigation water at 0.96,0.96 and 1.33 kg per 667 m2 at the seedling stage,flowering and fruiting stage and fruit-bearing stage,respectively.The total yield and income of cucumber are increased by 20.62%and 31.44%respectively,the cumulative yield and income of tomato are increased by 16.87%and 18.90%respectively.Therefore,the potassium-calcium-magnesium nitrate compound fertilizer has good value of popularization and application in the production of cucumber and tomato.
