A kind of method for growing seedlings of Chinese catalpa seedlings in greenhouse

Abstract

The invention discloses a greenhouse seedling cultivating method for kalopanax septemlobus seeds.The method comprises steps of seed collecting, seed processing, seed sprouting, sowing, seedling stage management, outplanting and kalopanax septemlobus seedling cultivating.The greenhouse seedling cultivating method is characterized in that for the seed sprouting process, the bottom of a sprouting disc provided with holes at the bottom is loaded with vermiculite which is 5-6 cm deep, the vermiculite is watered with sufficient water, the disinfected seeds are broadcast on the surface of the vermiculite and covered with a layer of vermiculite of 1-1.5 cm, the sprouting disc is covered with a layer of gauze and watered with sufficient water, the sprouting disc is put in a sunlight greenhouse, the greenhouse temperature is controlled to range from 0 DEG C to 25 DEG C under natural lighting, and the sprouting disc containing the seeds is kept wet.According to the greenhouse seedling cultivating method for the kalopanax septemlobus seeds, highly integrated control over the whole seedling cultivation process is achieved, the method is easy to master, the obtained cultivated kalopanax septemlobus seedlings are high in survival rate, and the technology is convenient to popularize and specially suitable for large-scale industrial seedling cultivation.

Description

technical field [0001] The invention relates to the technical field of plant seedling cultivation, in particular to a greenhouse seedling cultivation method for thorn catalpa seeds. Background technique [0002] Prickly catalpa is an arbor tree species of Araliaceae, with a straight trunk and unique wood patterns. It is a high-quality material for construction and high-end furniture. With the improvement of people's living standards, the demand for high-quality wood has increased sharply, and the protection and utilization of its resources have attracted people's attention. There is obvious size-annual periodicity in the fruit setting of C. roxburghii, and the seed collapse rate is high. Moreover, the seeds of C. chinensis have the habit of deep dormancy. The main reason is that due to physiological post-ripening, without proper temperature-changing treatment, the emergence rate of natural seeds is too low. The conventional method is mainly to carry out variable temperatur...

Problems solved by technology

Sand storage is the main method for overwintering of almost all forest seeds. It is simple and easy to implement, but there is a problem, that is, after the seeds are stored in sand, it is extremely inconvenient to observe the germination state of the seeds, and the phenomenon of over-germination of seeds often occurs

For the method of variable temperature treatment, it is more inconvenient to place the mixed sand seeds indoors and in the cellar, and move them back and forth.
