In order to study the effect on yield and quality to tomato on sprayingalcium chloride solution, based on its different periods and different typesof consistency, the experiment adopts the method of two factors, which areA1: CaCl2 0.2 %, A2 CaCl2 0.5 %, A3 CaCl2 1% and B1: spraying in its incipientblossom period, B2: spraying in its incipient fruiting period, B3: sprayingin its flourishing blossom period, B4: spraying in its incipient blossom periodand incipient fruiting period, B5: spraying in its incipient fruiting periodand flourishing fruiting period, doing the experiment spraying CaCl2 solutionon tomato's leaves, based onN, P,K fertilizer. The experiment is divided into15 types of Treatment combination, A1B1,A1B2,A1B3,A1B4,A1B5,A2B1,A2B2,A2B3,A2B4,A2B5:,A3B1,A3B2,A3B3,A3B4,A3B5. By the following data analysis, the singlefruited weight, the yield of single plant, the yield of small area, the diseaserate of blossom-end rot, the hardness, the content of reducing sugar, titrableacidity, and the content of vitamin C, the result shows the followingconclusions.It promotes tomato yield to spray CaCl2 solution, based on its differentperiods and different kinds of consistency. It is significant to increaseyield of tomato to spray CaCl2 1% solution in its incipient blossom periodand incipient fruiting period, increasing the single fruited weight, thesingle plant yield and the yield of small area, increased by 10.4 % about singlefruited weight, by 54.5% to single plant yield, by 1.5 per plant about thenumber of fruit, by 19.0% to the yield of small area.It can prevent tomato from the rate of blossom-end rot of tomato better,based on its different periods and different types consistency. It can affectsignificantly on the rate of blossom-end to spray, based on its differentperiods, the disease rate being the highest in its flourishing blossom period,by 14.21%, the disease rate being the lowest in its incipient blossom periodand incipient fruiting period, by 14.21%. Among different types of operations,the highest rate of disease is in its flourishing fruiting period to spayalcium Chloride Solution of different kinds of consistency, by 14.21% on theaverage. The lower rate of disease is in the other period, by 1.84% on theaverage. The result tells us that the consistency of alcium chloride solutiontakes a less effect on blossom-end rot, and the spaying period is the key toprevent tomato from the disease.It promotes tomato's hardness to spray CaCl2 solution, based on itsdifferent period. Its hardness is increased by 0.16kg/cm2 to spray CaCl2 1%in its incipient blossom period and incipient fruiting period, compared withflourishing fruiting period.It promotes tomato's quality to spray CaCl2 solution, based on itsdifferent periods and different types of consistency. There are certainrelations to reducing sugar and Vitamin C content to spay different kinds ofCaCl2 consistency, "reducing sugar and Vitamin C being increased with the increasing of consistency. Its reducing sugar content is increased by 0.33% to spay CaCl2 1%, compared with 0.2%, and Vitamin C content is increased by5.6%. It can affect significantly on the reducing sugar content and vitamincontent to spray CaCl2, based on its different period, being significant inits incipient blossom period and incipient fruiting period, increased by 0.28,0.29, 0.43, 0.67g/100g, and vitamin C is 7.4%, 7.8%, 12.6%, 13.3%, comparedwith the other periods. It is the best to spray CaCl2 1% in its incipient blossomperiod and incipient fruiting period, Vitamin C and reducing sugar contentbeing increased. Compared with other grouping, reducing sugar content isincreased by 0.96g/100g, and the Vitamin C is increased by 23.9% at the most.It is a falling trend of tomato's titrable acidity with the increasingof spraying consistency. T itrable acidity is lowered by 0.03% to spray CaCl21%, compared with CaCl2 0.03g/100g. Spraying period takes a less effect ontomato's titrable acidity. Among the operations, tomato's titrable acidityis the highest to spray CACl20.2% in its flourishing fruiting period, andtomato's titrable acidity is the lowest to spray CaCl2 1% in incipient blossomperiod and incipient fruiting period, lowered by 0.16g/100g. This tells usthat it can lower tomato's titrable acidity when tomato aborbs the more Canutrition.
