Problems solved by technology

At present, the formula of the common treatment method is composed of various chemical components such as sodium hydroxide, potassium chloride, sodium chloride, naphthalene acetic acid, gibberellin and water. The disadvantage is that there are many chemical raw materials used, the cost is high and the pollution is serious; The cycle is long; the process is complex and not suitable for mass production; the seed germination rate is low

[0020] Example 1 A method for improving the germination rate of zoysia seeds

[0021] Methods as below:

[0022] 1) Pour the zoysia seeds into a NaOH solution with a mass percentage concentration of 4% to soak the seeds. The volume ratio of the NaOH solution to the seeds is 2:1. During the soaking period, it is necessary to stir frequently with a wooden stick to keep the upper and lower concentrations of the NaOH solution consistent. Make the seeds fully contact with the NaOH solution. During the soaking period, use a sieve with an aperture of 0.5 mm to remove the floating sundries and empty seeds on the surface of the solution. After soaking for 4.5 hours, filter the seeds with a sieve immediately, and add an appropriate amount of NaOH to the remaining solution according to its concentration. Prepare a 4% solution for continued use;

[0023] 2) Put the filtered seeds into a container, rinse the seeds with running water for 3-3.5 hours, until the pH value of the outflowing ...

Abstract

The invention relates to a method for improving seed germination rate of Zoysia japonica, for solving the problem of low seed germination rate of Zoysia japonica. The method comprises the steps of soaking seeds of Zoysia japonica in 3-5% NaOH solution under regular stirring for 4-5 h, filtering to collect seeds, placing in a container, rinsing with flowing water until effluent water pH is neutral, taking out the seeds, adding into a spin-drying, spin-drying the seeds in the spin-drying barrel for 8-10 min, soaking in 0.08-0.1% KNO3 solution for 20-40 min, taking out the seeds, adding into the spin-drying, spin-drying in the spin-drying barrel for 20-25 min, airing outdoors until water content reaches 10-15%, and bagging. The invention significantly improves seed germination rate of Zoysia japonica, reaches and even exceeds sowing lawn construction technical requirement of Zoysia japonica.

Description

technical field [0001] The invention relates to a technology for treating zoysia seeds, in particular to a method capable of improving the germination rate of zoysia seeds. Background technique [0002] Zoysia japonica (Zoysia japonica) has the characteristics of strong adaptability, vigorous growth, light-loving, drought resistance, disease and insect pest resistance, trampling resistance, salt and alkali resistance, heat resistance and barren resistance. It is widely used in preserved land and is recognized as an excellent warm-season turfgrass in the world. [0003] There are large areas of wild distribution in Liaoning, Shandong Peninsula and other places in my country. However, the natural germination rate of zoysia seeds is low, only 20-30%. However, the treatment technology of zoysia seeds in my country is relatively low, which cannot meet the requirements of being directly used for landscaping, sowing and building turf. Therefore, the development of zoysia seed tr...
