Water-culture variable-temperature germination-accelerating seedling-raising method for agropyron cristatum

Abstract

The invention provides a water-culture variable-temperature germination-accelerating seedling-raising method for agropyron cristatum. The method comprises the steps of preparing seeds of the agropyroncristatum, a sponge and a seedling raising plate; enabling the sponge to suck water to reach a jelly shape, putting the sponge into the seedling raising plate, and adding water to the height being two-thirds of the height of the sponge; uniformly spreading the seeds of the agropyron cristatum on the sponge, spraying mist to moisten the seeds, and covering the seedling raising plate by a seedlingraising plate lid for shading and moisturizing; putting the seedling raising plate into a constant-temperature box, setting the temperature at 14-16 DEG C, and keeping the temperature for 10-14h; thensetting the temperature at 19-21 DEG C, and keeping the temperature for 10-14h; taking down the lid, observing the whitening conditions of the seeds, after the seeds show white color (radicles beginto emerge), turning on an LED for illumination, and keeping illumination for 10-14h; performing observation, and when the radicle length of seedlings of the agropyron cristatum is 0.5-1cm, beginning to transplant the seedlings; moving the seedlings to seedling raising cotton by using tweezers; and performing cultivation for 13-17 days on the seedling raising cotton, and transplanting the seedlingsto a planting area. The method provided by the invention has the beneficial effects that the germination of the agropyron cristatum is quick, the germination rate is high, the survival rate of the seedlings is high, and the method is convenient for operation.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a seedling raising method for hydroponic wheatgrass. Background technique [0002] Icegrass is a halophyte native to Africa and other places. There are a large number of large vesicular cells on the leaves and stems, which are filled with liquid. It is crystal clear under the sun, just like ice crystals, so it is named Icegrass . Wheatgrass is rich in natural plant salts, amino acids, carotene and other substances. After eating, it not only quenches thirst but also replenishes nutrients. It is a vegetable with high nutritional value. [0003] Wheatgrass likes a cool and cool environment, avoid high temperature and humidity, likes sandy soil with good drainage, and should be in a dry, ventilated, and well-lit environment. Agropyresis is mainly propagated by seeds. The temperature at the seedling stage is about 20°C, and the temperature during the growth period shou...
