Five, interpretation of result
1, from output, the output of demonstration group exceedes 0.70 ton of control group, and volume increase ratio is 46.67%, and control mistake type composite fertilizer nutrient quality abundance, reasonable ratio are described, meets the growth rhythm of watermelon, has met its growth required.The most exquisite nitrogen of Watermelon Fertilization, phosphorus, potassium coordinate, and watermelon is to the demand of nutrient for being about 3:1:4, and the nutrients ratio of control mistake type composite fertilizer is 15:6:20, just meet its demand rule, add while production and all select high quality raw material, nutrient is sufficient, quality is high, has promoted growing of watermelon.
2, demonstration group fertilizer cost is low 75.26 yuan/mu compared with control group, reduces costs 22.81%.The in the situation that of fertilizer reducing application amount, output still exceedes coventional type composite fertilizer, and acting tells the truth understands " control is lost " effect of controlling mistake type composite fertilizer.Control mistake type composite fertilizer is lived chemical fertilizer nutrient by Van der Waals force and ion bonding force " net is caught ", form " Molecule interpenetration network structure ", both controlled the loss of nutrient, disperse again Nutrient distribution, reduce the absorption difficulty of root system to nutrient, conscientiously accomplished minimizing nutrient loss, extended fertilizer efficiency period, improved utilization rate of fertilizer, really reached " the more synergy of losing weight ".
3, from price, affected by quality of watermelon, the average price of demonstration group exceeds 0.40 yuan/kilogram of control group, and price raising ratio is 16.00%, illustrates that the proportion of N and K fertilizer in control mistake type composite fertilizer is suitable, and middle micro-kind is suitable, content is suitable.Between element, exist and mutually promote and mutual antagonism, as just existed antagonistic action between nitrogen potassium, watermelon is happiness potassium crop, nitrogen/potassium compared conference affects the absorption of potassium, reduce quality of watermelon, the proportion of N and K fertilizer of control mistake type composite fertilizer is suitable, when meeting nitrogen supply, the impact that potassium is absorbed is very little, does not affect sucrose accumulation etc.In addition, peasant is in the time giving Watermelon Fertilization, and in generally not noting, trace element supplements, cause quality of watermelon not high, in control mistake type composite fertilizer, contain trace element in boron, magnesium, zinc etc., can coordinate watermelon nutrition, promote photosynthesis, increase paintedly etc., improve quality.
