Problems solved by technology

Some units in China have established the seaside mallow clonal rapid propagation system through plant tissue culture technology, but this method is complicated to operate and requires relatively high conditions, and because the use of hormones may cause mutations in the clone, it is not suitable for the rapid propagation of the production unit. Promotion work

Embodiment 1

[0026] The green branch cutting propagation method of seaside mallow comprises the following steps:

[0027] (1) Cut the upper 10-20 cm semi-lignified stems of the main stem or the first-level branch from the vigorous seaside mallow plant in summer as cuttings. According to observations, after the cuttings are cut from the upper part of the main stem or the first-level branch, the axillary buds below it will germinate quickly and the branches will be drawn out. What's more, only one cutting is cut, which basically has no effect on the parent body of the cut cuttings. Promote growth. When conditions permit, cut thicker cuttings as much as possible. Practice has proved that the thicker the cuttings are, the stronger the root system will be.

[0028] (2) Keep 2-3 leaves on the upper part of the cuttings. Keeping proper leaves and producing nutrients through photosynthesis of leaves is an important material condition for rooting of cuttings. If the leaves are kept too much, th...

Embodiment 2

[0038] Change the concentration of the 20% transplanted spirit mixture solution in step (3) of Example 1 to 100ppm, and the remaining contents are the same as in Example 1.

Embodiment 3

[0040] Change the concentration of the 20% transplanted spirit mixture solution in step (3) of Example 1 to 200ppm, and the remaining contents are the same as in Example 1.

Abstract

The invention discloses a greenwood cutting propagation method for kosteletzkya virginica. According to the technical scheme, the method includes the steps that 1, 10-20 cm semi-lignified stem segments on the upper parts of stems or first-grade branches are cut to serve as cutting slips; 2, 2-3 leaves are retained on the upper part of each cutting slip; 3, the bases of the cutting slips are immersed in a 20% isolane mixture 20-200 ppm solution by 3-5 cm for 3-15 days; 4, a cutting medium and containers are sterilized with a disinfectant one day before cutting; 5, one rooted cutting slip is inserted in the medium of each container; 6, the stacked containers are covered with a sunshade net; 7, the medium is kept moist and is watered thoroughly at a time in the watering process; 8, quick-acting fertilizer is applied once every 7-10 days; 9, acclimatization and transplant are carried out. The method has the advantages of simple operation, low cost and good stability, does not influence normal growth and development of parents, avoids waste caused by transplant of cutting slips without the rooting capacity, ensures high rooting quality, and has good economic, ecological and social benefits.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a green branch cutting propagation method of seaside mallow. Background technique [0002] At present, the relatively mature seaside saline soil improvement technologies mainly include freshwater desalination, underground pipe salt drainage, and foreign soil planting, etc. These technologies require a lot of manpower and material resources, easily cause environmental pollution and damage, and have low long-term comprehensive benefits. It is an ecologically friendly improvement measure to achieve desalination and fertilization of coastal saline soil by planting halophytes. The seaside mallow introduced from the United States by Professor Admiration of Nanjing University in 1993-1995 belongs to this type of plant. Seashore mallow is a perennial herbaceous plant of Malvaceae, native to the saline marshes from Delaware to Texas on the eastern coast of the United States. It has the c...
