Study Of Cucumber Efficient Experimental Seedling Technique

Through the matrix of cucumber seed dry heat at different temperature on germination rate of cucumber, treatment effects of different formulations of influence on cucumber seedling emergence, before colonization of different water control and time effect on the final singling seedlings after speed, to explore suitable for industrialized matrix formulation, high efficiency breeding seed dry heat treatment time, temperature and the optimum time of water control to promote the development of cucumber, efficient, intensive breeding technology.First of all, cucumber seeds in the65～70℃for5h can effectively promote the germination, germination rate, of which65℃(5H) the highest germination rate under. Cucumber seedling growth of cucumber seed treatment at different temperatures show differences,65℃and65℃(24h) treatment of leaf length and width of the maximum, have obvious advantages. Growth of seedlings of different temperature are different, growth of seedlings treated at65℃cultivation, plant height is appropriate, seedling index, favorable to the formation of cucumber seedling, showed that65～70℃can adapt to the cucumber seed treatment, showed good growth of cucumber seedlings, seedling is strong, is the most suitable temperature of cucumber seedling.Second different substrates, seedling emergence rate of each processing performance basically not the same, B2(matrix5000g+two amine20g), C1(matrix5000g+two amine5g+10g urea), C3(matrix5000g+two amine15g+urea20g) higher than that of the control, the emergence of a good role in promoting. Cucumber seedlings growing out of5D after sowing different matrix treatment has shown differences. Changes of crop growth process of height can reflect the growth situation of crops, cucumber seedling growth of different substrate processing basic consistent, the highest C1(matrix5000g+two amine5g+urea,10g) is6.52cm. Cucumber seedlings growth difference after sowing of different treatment of10d further expansion, the highest C1,11.37cm, true leaves are up, leaf size is largest, have obvious advantages. The cucumber seedling traits closely related, interdependent, mutual restriction, the characters have varying degrees of interaction, the final effect of cucumber seedling quality, B2, B3, C1were better physical properties, but also has the nutrient buffering capacity of strong, able to adapt to the need of cucumber growth, show the cucumber seedling vigor, Miao Zhuang, is a good matrix cucumber seedling.Third, before colonization by short-term water control exercise to improve cucumber seedling adaptation and survival rate in different time of water control, the seedling seedling rate, viability, C1, C2, C3(water control time4days) the seedling speed,5days to recover at seedling, C1, C2, C3of seedling rate a good role in promoting, viability but C1, C2, C3as lower than control. Viability of B1, B2, B3treatment showed a special, viability, B2, B1B3were99.33%,99.33%,98.67%, viability is significantly higher than the control, seedling rate, B1, B2, B3processing instructions (water control time2days) into high vigour, seedlings speed is also fast, on cucumber seedlings, a clear role in promoting seedling management etc.
