A method for improving seedling emergence and seedling growth of Eleuthero jujube seeds in inland saline-alkali land

Abstract

The invention discloses a method for increasing the emergence rate and seedling rate of wild olive seeds in inland saline-alkali soil. The method comprises the following steps that 1, the wild olive seeds are soaked in water till one ends of outer seed coats are softened; 2, the soaked wild olive seeds are planted in a nutritive bowl and then are fully watered, and a medium of the nutritive bowl comprises nutrient soil and sandy loam soil at the ratio of 3:1-5:1; 3, after radicles protrude out of the outer seed coats, the water in the growing medium of the wild olive seeds is reduced to 50% to 60%; 4, when wild olive seedlings grow to generate 4 to 6 main leaves, the seedlings and the soil in the nutritive bowl are transferred into a field together. The germination rate of the wild olive seeds is above 95%, and the seedling rate in inland saline-alkali soil of the yellow river delta is above 90%. The aim of planting wild olives in inland saline-alkali soil of the yellow river delta is achieved.

Description

technical field [0001] The invention relates to a method for improving the seedling emergence and seedling formation of sage jujube seeds in inland saline-alkali land, in particular to the technical field of large-scale seedling cultivation of sage-zajube in inland saline-alkali land. Background technique [0002] The Yellow River Delta is located in the northern part of Shandong Province, with 5.3×10 5 hm 2 Saline-alkali land, and the area of ​​saline-alkali land is still at an annual rate of 1.3×10 5 hm 2 The groundwater level in the saline-alkali land of the Yellow River Delta is high and the salt content is high; the content of organic matter, nitrogen and phosphorus is low; the nutrients are unbalanced; the physical and chemical properties of the soil are poor, and it is dry in spring and prone to waterlogging in summer. It is not suitable for the growth of conventional garden plants. Now the greening method in the Yellow River Delta mainly adopts the method of diggi...

Problems solved by technology

[0007] Although it is mentioned in the prior art that planting Elaeoptera in saline-alkali land as a greening method, such as patent 201410013793.0, it is precisely because of the problems that the above-mentioned Elaeoptera is directly planted on saline-alkali land that the prior art mentions planting Elaeoptera in saline-alkali land as a greening method. The method can only be to grow seedlings by purchasing ready-made seedlings of Eleuthermus jujuba and planting them as mother plants. This method has a long period and complicated management steps after cutting. At present, there is no improvement in the emergence and growth of seeds of Eleuthero sativa in inland saline-alkali land. effective method
