Study On Standardized Cultivation Techniques Of High Yield And Quality Of Huangfei Cherry Tomato In Spring Greenhouses

Cherry tomato coming from South America is a member of the tomato family, and it is the ancestors of cultivated tomato. It has strong root system and ability of regeneration, drought tolerant and heat-resistant, and it can be wide adaptability. Because of cherry tomato’s bright color, graceful shape, palatable taste and rich nutrient, its value get more attention and demand increced year by year. In recent years, although some south provinces have began to plant cherry tomato, its output can’t be afford the market. With huge market potential, cherry tomato’s economic value can sti667m2late the market make themselves bigger scale than before. In order to increase Huzhou city’s economical, farmers’income and satisfy the demand of high quality cherry tomato, it introduced a new kind of cherry tomato named huangfei from Japan in2011.With two year’s plant experimentally, huangfei shows as good quality, strong resistance, high yield and good benefits. Through studying on the difference of breeding method, fertilization, planting density, fruit thinning methods, this research develop a standardization cultivation techniques for suitable local environment.Through studying on the difference about different breeding methods21-hole and nutritional bowl (72-holes) in the time of60d(40d),80d(60d),100d(80d),120d(100d), contrasting breeding quality, fruit number and characters, it found that breeding age of80days by nutritional bowl can get the highest yield, fruit shape and sugar content could reach the target of high yield and high quality and that breeding by72-hole can reach the target of breeding cultivation in the shortest time.Through the study of different effects of compound fertilizer-potassium sulfate (kg-kg) on different fertilization treatments in40-40,30-30,20-20,10-10,0-0, contrasting the yield, single fruit weight, sugar content, it found that fertilizer had an unsignificant effect on fruit weight and sugar context, but a significant effect on the yield. In the fertilization under "20-20", that can get the maxi667m2m yield.Through the study of the effect of cherry tomato yield on the4different planting density of1300plants/667m2,1800plants/667m2,2300plants/667m2,2800plants/667m2, contrasting yield, single fruit weight, sugar context, it found that planting density had significant effect on yield, and planting density of2300plants/667m2can make it best. With increasing the planting density, the. single fruit weight and sugar context decreased. Considering of cost, yield and other factors. the most suitable density is1300-1800plants/667m2,Through the study of the effect of cherry tomato yield on the4different fruit thinning of80,100,120, non, contrasting yield per plant, yield per667m2, single fruit weight, sugar context, it found that with fruit thinning degree increased, yield per plant did not fall but rise. And that the93fruit per plant has the highest yield of691.5g/plant, that non thinning (150fruits) has the lowest yield of521.5g/plant.Through the design of for667m2lation yield planting scheme:nutritional bowl seed, breeding age is75-day, the planting density is1300plants/667m2, fertilizer application amount is compound fertilizer-potassium sulfate in20-20kg/667m2, fruit thinning is100. The results show that three greenhouses yield is1517～4711kg/667m2, and the average is1595kg/667m2. As the target of yield is1500kg/667m2, this method can be right.Finally, according to the experimental results and previous experimental data, it develop a standard cultivation techniques of high yield and quality for huangfei cherry tomato in spring greenhouse by Huzhou local environment.
