The Study Of Flower Forcing Technique And Production Of Phalaenopsis In Sunlight Greenhouse In Ningxia

The experiment carries out different varieties of Phalaenopsis as test materials for flowering and flower induction and growth control test in summer and winter, so as to provide a theoretical basis for Phalaenopsis cultivation in Ningxia area, the results were as following:1.Solar Greenhouse in summer and winter of Phalaenopsis flower varieties screeningThe test of flowering of Phalaenopsis in Greenhousein summer began with introduction of Phalaenopsis.BigChilies,Phal aenopsis.436,Phalaenopsis.867,Phalaenopsis.TaipeiGold,Phalaenopsis. Fuller’s sunset, Phalaenopsis.Wedding Promenade, Phalaenopsis.531, Phalaenopsis.Fire Bird, Phalaenopsis.Maple leaf,9varieties of seedlings of 3.5 inches were introducted.for flowering test. The results showed that the Phalaenopsis Big Chiliesvarieties handed more flowers, more leaf number, earlier blossom, longer florescence, larger flower, brighter color,was the most suitable for planting in Ningxia area, the comprehensive characters were ordered Phalaenopsis.867> Phalaenopsis 436>Phalaenopsis.TaipeiGold>Phalaenopsis.Fuller’ ssunset>Phalaenopsis.WeddingPr omenade>Phalaenopsis.531>Phalaenopsis.FireBird>Phalaenopsis.Maple leaf.The introduction of Phalaenopsis.King of empire、Phalaenopsis.Brother Girl、Phalaenopsi s.Taibei Gold、Dtps.Ben Star’Red Dragon’, Phalaenopsis.SH,Phalaenopsis.159,Phalaenopsis.

The results showed that the Phalaenopsis.Red Sun haved more leaf number, earlier stalk blossom, longer florescence, larger flowers, brighter color,was the most suitable for planting in winter in Ningxia area, the comprehensive characters of varieties were ordered Phalaenopsis.159>Phalaenopsis.Fuller’s sun set>Phalaenopsis.King of empire>Dtps.Ben Yu Star’Red Dragon’>Phalaenopsis.SH> Phalaen opsis.021>Phalaenopsis.Brother Girl>Phalaenopsis.Taibei Gold.2 Effects of fertilization treatments on the Phalaenopsis amabilisEffects of different fertilization treatments on the growth of Phalaenopsis,using different pr oportions USA scots of N,P,K on the Phalaenopsis, the results showed that, the vegetative gro wth stage appropriate to increase the proportion of N,which can promote plant nutrient accumul ation, and the formation of mature plants became strong, which was beneficial to the Phalaeno psis.Different concentration of trace elements test, nutrient elements tested with three factors and three levels of B,Zn,Fe by adjusting the H3BO3. ZnSO4· 7H2O, Fe SO4 fertilizer concentration to control B,Zn,Fe, the results showed that as Fe was increasing, N content decreased, but B,Zn have little effect on N leaves; elements of B,Zn,Fe for P effect is not obvious;Zn plays a major role on Phalaenopsis leaf of K, next was Fe,B.0.23mg/1 B,0.20mg/1 Zn and 3.75mg/1 Fe showed the best combination of Phalaenopsis vegetative growth stage; 0.23mg/1 B,0.40mg/1 Zn and 1.86mg/l Fe combination was the best performance of pedicel and floral traits of Phalaenopsis.3 The three plant growth regulators on Phalaenopsis flowerThe test of two plant growth regulators were spraying on influence of flower bud differentiation rate, using design of randomized block with B9,6-BA, the results show that,,6-BA can promote the early blossom for the top three average flower flowering,50mg/L B9 can delay,6-BA can increase the number of flowers in Phalaenopsis to a certain extent, but the number of flowers, flower arrow Phalaenopsis flower arrow height and flower diameter effect were relatively low; the influence of B9 for the number of Phalaenopsis flower, flower diameter,the arrow height and the flower were very small.Two kinds of plant growth regulator treatment smear test, which used randomized block design by smearing treatment of 2 levels of 6-BA, GA to find out the influence of 2 kinds of plant growth regulators on flower bud differentiation,the research show that,5mg/kg 6-BA,50mg/kg 6-BA, 50mg/kg GA3 flower bud differentiation rate is higher,25mg/kg 6-BA,50mg/kg GA3 can increase the blossom rate effectively; 50mg/1 6-BA,25mg/kg GA3,50mg/kg GA3 increased to a certain extent on the number of Phalaenopsis flowers, but the number of Phalaenopsis flower blossom flower arrow, arrow height and diameter of flower were not affected significantly.
