Embodiment Construction

[0012] The beneficial effects of the present invention will be further described by examples below:

[0013] Guizhou stone pencil wood seed rapid propagation and high-quality seedling cultivation method comprises the following steps:

[0014] (1) Sowing:

[0015] The dark stratification treatment of Guizhou stone pencil wood placed in a constant temperature box at 20°C kept a relative humidity of 80-90%, and seeds germinated after 40 days; Seeds of penwood are stratified with perlite at 20°C without light, and the seeds will germinate after 40 days. The emergence rate at normal temperature is 32%, and the emergence rate at 20°C is 67%. Stratification at 20-25°C; The average emergence rate of sowing at room temperature is 25.83%, and the average emergence rate at 20°C is 55.67%;

[0016] The above comparison tests show that the seeds are stored in air-dry, sow in March of the following year, and soak the seeds in water for 24 hours before sowing, which can shorten the time of...

Abstract

The invention discloses a rapid propagation method of Tutcheria spectabilis seeds in Guizhou and a cultivation method of fine seedlings, including : (1) sowing: seeds are laminated in the incubator where the temperature is at 20-25 DEG C, the incubator is ventilating and has penetrating light, the humidity is 80-90%, and some seeds germinate after 40 days; sow seeds in the seedling box in greenhouse at 20 DEG C, the covering soil is 2 cm thick, water the soil regularly to keep the soil moisture, seedlings emerge after 80 days, after that pour 500 times Carbendazim and N.P.K fertilizer. (2) breeding technology: after seeds germinate well, transplant them into a field, dig the soil which is soft more than 25 cm, spray bed soil with 5% potassium permanganate and 400 g / m[2] Zinc Suiphur Phophorus emulsion to disinfect the soil, pour 100 g / m[2] Calcium Magnesium Phosphate as the ground fertilizer, transplant the seedlings in a cloudy day, shield them with shelter, pour a little water often, fertilize them, and fertilize them with urea solution 3-4 times one year; after the seedlings grow up, control the water and fertilizer according to the regulation. The invention has the merits of production in scale, high survival rate, short-cycle output and superior quality seedlings.

Description

technical field [0001] The invention relates to a method for seedling cultivation, in particular to a method for rapid seed propagation and high-quality seedling cultivation.
