[0013] 1 Materials and methods

[0014] 1.1 Materials

[0015] The cucumber (Cucumis sativus L.) used in the test is a European miniature cucumber "Spring and Autumn King", provided by Shanghai Academy of Agricultural Sciences.

[0019] Soak cucumber seeds to accelerate germination, then sow them in 50-hole hole trays, and transplant them into 20cm*20cm plastic flower pots after the first true leaf unfolds. At the time of heart (early May, 2011), the root flooding test was started. The flooding was based on the standard of 1 cm above the soil surface. Each treated 6 plants and repeated 3 times. Use a small amount of 1mol·L -1 Dissolve 6-BA (produced by Sinopharm Chemical Reagent Co., Ltd.) in NaOH solution, and then add double dist...

Abstract

The invention discloses a cultivation method of spraying an exogenous material 6-BA on the leaf surface to improve water logging resistance of cucumber. The cultivation method is characterized by including that the cucumber grows under a condition that the root is drown, and the 6-BA (6-benzyl amino adenine which is one of cytokinin and an important plant growth regulator) is sprayed on the leaf surface; optimal 6-BA concentration is selected by spraying the exogenous material 6-BA different in concentration on the leaf surface, cucumber plants which are high in water logging resistance and good in physiological and biochemical index and growth vigor are obtained, and the selected optimal 6-BA concentration is 5 micromole L-1; the variety of the cucumber is 'Spring-Autumn King' which is provided by the Institute of Facility Horticulture of the Shanghai Academy of Agricultural Sciences. By the cultivation method, the problem that the cucumber is poor in water logging resistance is effectively solved.

Description

1. Technical field: [0001] The invention relates to a cultivation technique for improving the waterlogging resistance of cucumbers, in particular to a cultivation technique for improving the waterlogging tolerance of cucumbers by spraying exogenous substance 6-BA on leaves. 2. Background technology: [0002] my country is a country with frequent flood disasters, especially in summer flooding in the south, which poses a great threat to agricultural production and high-quality and high-yield vegetable crops. In addition, the soil in many areas is heavy and sticky, which further increases the loss of production caused by flooding. At present, There is still no better mitigation. Plant cytokinins are an important class of plant growth regulators, which can regulate the differentiation and expansion of plant cell tissues, and also have regulatory effects on different growth and development stages of plants, such as delaying senescence, balancing root / shoot ratio, inducing cell div...
