Strawberry Soilless Cultivation Of Suitable Varieties And Growing Media Screening Evaluation

In this paper, the strawberry Soilless Cultivated Varieties and matrix screening conducted2tests,experiment1: in "Toyonoka" varieties as materials, using5matrix processing, researcheffects of physicochemical properties, substrate temperature change law and the growth,physiological and biochemical, yield，quality of strawberry nutrition; Experiment2: using a specialmatrix, the study of7varieties，on the change in the early cultivation maturity, high yield，diseaseresistance, yield, quality. The results show that:1different matrix processing:(1) bulk density,EC5matrix showed a rising trend, the change of EC significantly, peat+slagchange amplitude minimum; total porosity、pH showed a downward tr e n d, special matrix withminimal changes,5.38%and1.69%.(2) change and temperature of5kinds of substrate temperature (Shi Wen) had a positivecorrelation; in diurnal variation, diurnal minimum as the special matrix (4.8℃), peat+vermiculitecompared with special matrix, smaller amplitude.(3) root activity: peat+slag、 peat+vermiculite, ratio of special matrix respectively increase6.98%,4.47%,1.15%.(4) production: special matrix for the highest yield (748.67g/strain), followed by the peat+vermiculite (743.20g/strain),no significant difference between the two; yield time distribution,peat+vermiculite sustained yield better than the special matrix; peat+vermiculite average fruitweight maximum17.1g is better than that of special matrix, significant differences between thetwo.(5) quality: between the5treatment on strawberry flavor difference matrix effect, differencebetween treatments was not obvious. Peat+mushroom residue flavor the best ratio of sugar to acid14.36, followed by the peat+vermiculite,peat+slag is better than that of special matrix.(6) Through the fuzzy comprehensive evaluation combined with the substrate temperature,changes of physicochemical properties evaluation: peat: vermiculite=1:1is better than that ofspecial matrix, can greatly reduce the cost of the matrix. Peat: slag=1:1and special matrix, thedifferences were not significant, and the utilization of industrial waste, and has the applicationvalue of long-term in production.2The matrix facilitates the cultivation of varieties test(1) resistance of varieties: Confidante、Long cited a number better than Toyonoka (CK); plantdisease resistance, Tongzi1high resistance to disease, Rose disease-resistant, Long cited anumber,、Zhang Ji disease tolerance. The occurrence of powdery mildew of fruit, the most seriouslad Toyonoka, Tongzi1、rose high incidence of Botrytiscinerea; The incidence of Botrytis fruit,Tongzi1、Rose、Confidante、Long cited a numbe is resistant cultivar.(2) the phenological period: Long cited a numbe、rose、Toyonoka extremely early maturing variety, mid November to belisted; Confidante, Zhang Ji, Xingxiang early maturing varieties, earlyDecember listing; Tongzi1is the early maturing varieties, listed in late December.(3) yield characteristics: the highest yield for the Tongzi11381kg/mu, then Rose、 Zhang Ji,Confidante than Toyonoka yield by25.20%、21.70%、9.75%、5.53%; the yield distribution isrelatively concentrated time, the best boy Tongzi1stability.(4) the comprehensive evaluation: Tongzi1、Confidante、Zhang Ji、Rose Cultivars Suitablefor facilities substrate culture, which the Tongzi1best, followed by Confidante. The Tongzi1canbe used as matrixcultivation facilities preferred varieties, suitable for exported; Confidante suitablefor Suburban Sales; Zhang Ji suitable for High-grade fruit box; Rose suitable for use as low sugarhealth care and excellent ornamental potted cultivars.
