Effects Of Fulvic Acid Potassium And Amine Ester On The Growth And Yield Of Tomato Growing In Rockwool

1.The effect of fulvic acid potassium and amine ester in the nutrient solution on the growth of rock wool tomato plants during flowering and fruit bearing stage was significant,and still had a promoting effect in the fruiting stage.2 Potassium fulvic acid and amine ester in nutrient solution improve the content of stem and leaf nitrogen phosphorus and potassium on tomato plants at flowering and fruit setting stage.When DA-6 single treatment or compound with moderate concentration of fulvic acid potassium can promote the content of N?P?K on flowering and fruit setting stage.Full fruit period,the content of nitrogen phosphorus and potassium in stem and leaf still improved by DA-6 with high concentration of potassium fulvic acid.Later fruit period,fulvic acid potassium single medium concentration or medium concentration of amine ester compound can promote the late NPK contents in leaf and stem.Therefore,M15D2.5 addition in the rock cotton tomato cultivation had a good effect on the absorption of N,P and K in the whole stem.3 Effects of fulvic acid potassium and amine ester added in nutrient solution of wool tomato on soluble sugar of fruits did not reach significant level.2.5mg/L of amine ester single treatment or 15mg/L of fulvic acid potassium and amine ester compound can promote vitamin C in fruit.30mg/L of fulvic acid potassium used alone,or 30mg/L of fulvic acid potassium and amine ester compound can improve the ratio of sugar to acid.M15D2.5 and M15D5 have better effect on rock wool tomato cultivation of fruit quality.4 Potassium fulvic acid and amine ester added in nutrient solution improve the yield of wool tomato.M15D2.5 treatment improve early yield?mid yield and total output production significantly.Vegetables such as Tomato in Greenhouse of the brick wall structure is an important production technology of Huang Huai's in winter.However the environment in Solar Greenhouse in winter,low temperature and weak light leads to low root activity and weak growth potential.Hot summer humidity make salt accumulate easily.The combination of fulvic acid and fresh amines in the whole growth period of nutrient solution will increase the complexity and extreme environment of the rock wool tomato in the solar greenhouse in winter,and play a promoting role in different periods,and cooperate with each other.It has significant effects on promoting stable production of premature rice and improving the quality of Tomato.A small amount of cheap mineral potassium fulvic acid can be combined with amine fresh ester to replace some of the higher price amines.It can increase the temperature range of amines and esters and promote early maturity.
