Embodiment 1

[0020] A method for growing seedlings by cuttings of Yinji xiaowa, comprising the following steps:

[0021] (1) Prepare matrix: mix perlite and peat soil according to the weight ratio of 5:1, soak it in a potassium permanganate solution with a weight ratio of potassium permanganate and water of 1:800, and perform sterilization treatment , After soaking for 24 hours, rinse off the potassium permanganate with water to obtain the matrix, and set aside.

[0022] (2) Selection and pretreatment of cuttings: select semi-lignified branches from the female parent of Yin Ji Xiaowa to cut the ears, cut the cut branches into 8-10cm long cutting branches, keep 2 buds, 2 Cut the upper end of the cutting branch flat, 1-1.5cm away from the upper bud, and cut the lower part obliquely, with a smooth cut.

[0023] (3) Preparation of nutrient solution: the chlorothalonil of 75% wettable powder, fast-growing roots and water are uniformly mixed to obtain a nutrient solution, and in the nutrient so...

Abstract

The invention belongs to the technical field of seedling cultivating, and relates to a cuttage seedling cultivating method of Ligustrum sinense cv. Variegatum. The method includes the steps of selecting a semi-lignified annual branch of a parent, shearing the annual branch into a cuttage branch 8 cm to 10 cm long, keeping 2 to 3 buds and 2 to 4 leaves, shearing the upper end of the cuttage branch flat, obliquely shearing the lower portion 1 cm to 1.5 cm away from the bud above to form a smooth shear opening, inserting the cuttage branch into a sterilized perlite and turfy soil mixed medium after placing the cuttage branch into a culture solution to be soaked for 1 hour to 2 hours, and conducting bare-root transplanting 40 days to 45 days after the cuttage branch is cultivated in the sterilized perlite and turfy soil mixed medium. The mixed medium formed by perlite and turfy soil according to the weight ratio of 5:1 is adopted as the cuttage medium, and the method is high in breathability and moisture absorption performance, low in cost, beneficial to root system growth and high in rooting rate; through the soaking process, cutting slips are soaked in the nutrient solution for 1 hour to 2 hours, and therefore roots of the cutting slips have sufficient time to absorb nutrients in the nutrient solution and are then cut into the well-prepared mixed medium, root nodules are formed 5 days to 7 days later, rooting is achieved 13 days to 15 days later, the bare-root transplanting can be achieved 40 days to 50 days later, the survival rate is high and can reach 95% or above, and the seedling establishment cycle is short.

Description

technical field [0001] The invention relates to a plant breeding technology, which belongs to the technical field of nursery stock breeding, and in particular relates to a method for growing seedlings by cuttings. Background technique [0002] Ligustrum sinense is an evergreen small tree of the Oleaceae family. It is distributed in Japan, the Korean Peninsula, my country's Liaoning and the vast areas to the south. It can withstand -25°C and is highly adaptable to climate. It is a positive plant and likes strong light. , extremely cold-resistant, drought-resistant, barren-resistant, and pruning-resistant, with a medium growth rate. It can reach 30-50 cm in one year depending on the pruning condition. It can form a shrub ball of 0.7-1 m in 2-3 years. The base color of its leaves is silver-green. It is milky white with irregular width and narrow leaves. The leaves are slender. The leaves are about 2 cm long and 1 cm wide. The silver-green and milky-white small trees form a strong...
