Embodiment 1

[0021] On May 20, 2008, mature green Carex seeds were harvested in the Xiaotangshan base of Beijing Grass Industry and Environmental Research and Development Center, and stored in mesh bags after air-drying. On June 1, weigh 1g of seeds and soak them in 100ml 3g / L potassium nitrate solution KNO 3 In the beaker of the aqueous solution, the beaker 24 is placed in a 38°C incubator. After soaking, stir once every 30 minutes. After soaking for 12 hours, take out the sunken seeds, add 3 times of wet sand, and store them in a constant temperature box at 25°C. After 10 days, take out the stored seeds, wash away the fine sand through a sieve with clear water, gently crush the rotten seeds and empty shell seeds on the sieve, and select them with clear water to obtain pure and plump green carex seeds. The selected seeds were mixed with 3 times the amount of dry sand and spread in the flat plate of the greenhouse. Seedlings began to emerge after 3 days, and the emergence rate reached 82%...

Embodiment 2

[0023] The seed selection procedures were all carried out as in Example 1, except that the soaking temperature of the seeds was 25°C. After the selected seeds are sown, seedlings begin to emerge after 5 days, and the emergence rate reaches 78% after 8 days.

Embodiment 3

[0025] The cutting procedure is all carried out according to embodiment 1, the difference is that the seed soaking solution is that the concentration is 500mg / L GA 3 , soaking time is 24h. After the selected seeds are sown, seedlings begin to emerge after 3 days, and the emergence rate reaches 84% ​​after 8 days.

Abstract

The invention provides a carex breviculmis seed cleaning technique, which comprises steps of soaking carex breviculmis seeds in an aqueous solution for screening, storing the seeds in sand till embryos of the seeds swell after absorbing water, and wet cleaning. The carex breviculmis seed cleaning technique solves the problems that the germination of the carex breviculmis seeds requires long time and is uneven and the rate of emergency of the carex breviculmis seeds is low, and with the technique, the seedlings of the carex breviculmis seeds are planted directly, and the rate of emergency of the seedlings can reach 90 percent in 6 to 8 days. Therefore, the technique can realize direct seeding and application of the carex breviculmis seeds.

Description

technical field [0001] The invention relates to a method for selecting seeds of Carex breviculmis. Specifically, it includes 3 steps of soaking and screening the green carex seeds in aqueous solution, and then washing them in sand. Through this seed selection method, the problem of long germination time and irregular germination of the green carex is solved, so that the green carex can be produced live. and apply. It belongs to the field of agricultural biotechnology. Background technique [0002] Carex is a perennial herb of Cyperaceae (Cyperaceae), with about 2,000 species in the world, and more than 500 species of Carex in my country (Xue Hong et al., General Research on Carex, Journal of Qiqihar University, 2005, 21 (4) : 81-86), Carex has the characteristics of turning green early in spring, long growing season, drought-resistant, trampling-resistant, and barren-resistant in northern my country, and has good ornamental value. It can be widely used as lawn and ground c...
