Effects Of Planting Season On Frozen Strawberry Seedling On The Growth And Fruit Quality

In order to overcome the influence of high temperature and long day in summer on reproductive growth of strawberry, to be able to have a harvest from June to September, and to realize the production and supply of fresh strawberry anniversary, the effects of planting season on growth status and fruit quality of frozen strawberry seedlings was studied. The results show that:1. As the summer planting time delayed, strawberry planting survival rate, growth status (increment of plant height, diameter of stem, petiole length and leaf area) leaf chlorophyll content and root activity was decreased. The aspect of strawberry fruit size, color brightness weakening, internal quality has tended to become bad. the soluble solid content, Vc, reducing sugar and titratable acid decreased.2.Among the four varieties tested, the planting survival rate of San andreas and Portola were the highest, followed by Albion, Benihoppe minimum. In the summer high temperature and long sunshine adversity, the fruit number of Benihoppe strawberry was less, yield was low, reproductive growth capacity was weak, not suitable for cultivation in summer. In corresponding condition, Albion, San andreas and Portola grew normally, had more fruit set and higher yield, were more suitable for strawberry cultivation in summer.3.Compared with plain country in shuangliu county, the fruit appearance quality of summer cultivation strawberry in Hanyuan mountain area was better, and the yield was higher, Compared with plain country in shuangliu county, the fruit appearance quality of summer cultivation strawberry in Hanyuan mountain area was better, and the yield was higher. The fruit yield per plant of San Andreas and Albion strawberry were reached 378.71 g and 406.81 g. This shows that in the high temperature and long sunshine conditions, the high mountain climate conditions in Hanyuan were more suitable for strawberry cultivation in summer.4.There are still many problems to cultivate frozen strawberry seedling in summer, such as strawberry vegetative and reproductive growth in this test is not good enough, the index of fruit quality and yield was lower, far did not achieve the normal levels of the varieties tested. In order to realize the high yield, stable yield and high quality of strawberry production in summer, it is also to further explore and improve the present strawberry cultivation techniques..
