Simple efficient cultivation method for raising seedlings of Mesembryanthemum crystallinum L.

Abstract

The invention discloses a simple efficient cultivation method for raising seedlings of Mesembryanthemum crystallinum L.. The method comprises the steps of: immersing seeds of Mesembryanthemum crystallinum L. until the seeds is whitened before sowing is conducted; filling holes of a seedling raising tray with a mixed substrate of turfy soil and sand loam and vermiculite from bottom to top sequentially, wherein the filling volume of the mixed substrate accounts for 3 / 5-4 / 5 of the volume of the holes, and the filling volume of the vermiculite accounts for 1 / 5-2 / 5 of the volume of the holes; pouring the substrates with atomized water, taking germinated seeds to centers of the holes through absorption, and after sowing is conducted, putting the seedling raising tray in an backlight environmentwhich has a temperature of 20-25 DEG C, a relative humidity of 60-80% and an air velocity of less than 0.5-1 m.s<-1>, wherein no covering of surfaces of the seeds with arbitrary substrates is needed;and when the seedlings of the seeds emerge 2-3 days later, and after the surface of the substrates is dry, performing spraying by using the atomized water. Through the substrates and the arrangement relationship of the substrates, roots of Mesembryanthemum crystallinum L. are promoted before and after the seedlings emerge, the emergence rate is improved greatly and can reach 95% or above, the emergence time is short and can be 2-3 days, and no seedling thinning and two-time seedling transplanting are needed, so that the cost is saved greatly.

Description

technical field [0001] The invention relates to a simple and high-efficiency seedling-raising and cultivation method for Iceleaf japonica, belonging to the technical field of plant cultivation. Background technique [0002] Ice leaf Rizhonghua (Mesembryanthemum crystallinum L.) is an annual succulent herbaceous plant of the Apricotaceae, Mesembryanthemum crystallinum genus. Because of its very unique taste and high nutritional value, it has been widely planted as a new and special variety of functional vegetables in recent years. However, due to the obvious difference in cultivation and management of Bingye Rizhonghua and ordinary vegetables, it likes light, avoids waterlogging, is afraid of humidity, and is resistant to drought, so it is suitable for cultivation in an environment with good drainage conditions. Seriously affect its normal growth, and places with too much rain are not suitable for cultivation. Therefore, the corresponding cultivation measures are the key to...

Problems solved by technology

The second type is adopted by most growers; no matter what kind of seedling raising method is adopted, the traditional seedling raising substrate usually uses 60% humus, 15% perlite, and 25% vermiculite. Due to the influence of the substrate on the root system, the emergence rate is low. Very low, the emergence rate is about 30%; the emergence time is long, about 7-10 days, and the emergence is uneven; and thinning and transplanting both increase the production cost

The hydroponic method of the ice leaf Rizhonghua uses hydroponic liquid instead of the cultivation site for hydroponic cultivation. The emphasis is on the nutritional formula seedling substrate of the hydroponic liquid still adopts the traditional seedling cultivation substrate, which still has low emergence rate, long emergence time, and uneven defect
