Test crop: tomato
	 
	Fertilizer application period: seedling stage and early flowering stage (once each application)
	 
	Fertilization time: June 14 and 22, 2016
	 
	Test site: Changqingyuan Farm, Huiji District, Zhengzhou City
	 
	Testers: Yu Zhaoli and Wang Jianwei
	 
	Time of investigation: 2 July 2016
	 
	I. Test Purpose
	 
	Field experiments were conducted to verify the effects of root tonic on vegetative growth, flowering and fruit hanging of tomatoes, and to provide practical basis for the promotion and application of root tonic and flushing fertilization.
	 
	II. TEST MATERIALS
	 
	Test product: root tonic (5kg/barrel)
	 
	III. Test Design
	 
	3.1 dosage setting
	 
	Test treatment: root tonic (5kg/mu); control: the same kind of manufacturer spraying fertilizer
	 
	Usage: flush with water
	 
	3.2 Trial Arrangements
	 
	Three treatments were arranged: 5kg/mu.
	 
	Processing area: 2 square meters, each processing and set three repetitions.
	 
	3.3 Investigation methods and contents
	 
	Method of investigation: Five-point sampling method was used and five points (2 trees per point) were investigated for each treatment.
	 
	Content of investigation: plant height, number of fruit hanging.
	 
	IV. RESULTS INVESTIGATION
	 
	4.1 Effect of Root Force Supplement on Tomato Plant Growth (see figure below)
	
	 
	 
	
		CONCLUSION: The growth of tomato plants is good, the plant height is obviously increased, the plant bifurcation is more, and the height of tomato plants is increased by 23.19% compared with the control.
	
		 
	
		Effect of 4.2 Root Force Supplement on Tomato Fruit Hanging
	
		 
	
		Table 1. Effect of Root Force Supplement on Tomato Fruit Hanging
		
		
		CONCLUSION: Tomato larvae were fed with root tonic flushing fertilizer at 5 kg/mu interval of 8 days. After two times, the number of fruit hanging increased by 21.95% compared with the control. Compared with the control, the tomato plants in root tonic test had uniform fruit color, good fruit shape and more fruit hanging quantity, which could increase the yield per mu of Tomato and increase the income.
	
		 
	
		V. CONCLUSION AND DISCUSSION
	
		 
	
		The results showed that the tomato plants grew well, the stalks were strong and the leaves were dark green, which was beneficial to fruit coloring, good selling and increasing yield. Root tonic is rich in a variety of nutrients needed by plants, which can meet the nutritional needs of tomato larvae during the whole growth period.
