Description

A kind of ground cover bamboo industrialized seedling raising method

technical field

The invention relates to the technical field of forestry, in particular to an industrialized seedling raising method of ground cover bamboo.

Background technique

Bamboo is widely used, has high economic value, and has important ecological protection functions. China is the kingdom of bamboo, with an area of more than 7.2 million hm ² of bamboo forests, of which the area of artificially managed bamboo forests is 5 million hm ² , accounting for 10% of the total area of plantation forests in China. %, bamboo industry, as the first of the ten sunrise industries of China's forestry, has become a pillar industry for the development of southern hilly and mountainous areas. Bamboo is a long-period one-time flowering plant. Most bamboo species die after flowering, so it is generally impossible to use conventional seedlings for afforestation. The current common bamboo rapid propagation and seedling method is to use bamboo stalks as propagation materials. The side branches and side buds of the second level and after the second level germinate and root and embed for seedling cultivation (200410040564.4), or use clump-like small bamboo seedlings with underground stems as small mother plant materials to plant in the nursery ground to propagate new bamboos. The culm base length of new bamboos to be germinated After rooting, the new bamboo is separated from the mother plant, and then the new bamboo and the mother plant continue to be cultivated and propagated in situ. When the new bamboo grows roots and the side branches are drawn out, the new bamboo is transplanted into a seedling bag and cultivated into a bag seedling of a complete small plant (200910040748.3), Or adopt bamboo branches to carry out cutting seedling raising (201110061517.8; 201110062629.5). The above-mentioned technology is only suitable for medium-diameter bamboo or large-diameter bamboo, and is not suitable for small-scale ground-cover bamboo. The current ground-cover bamboo afforestation and seedling cultivation are mainly splitting. This method has low seedling efficiency and high cost, and is difficult to meet production needs. The application and development of groundcover bamboo in gardens.

At present, the application of ground cover bamboo in gardens is mainly used for slope protection, building bamboo flats, and restoration of bare land under forests. For a long time, ground cover bamboos have been propagated naturally and asexually mainly in nurseries. Although ground cover bamboos in the natural state have a faster propagation rate, they are in short supply compared with the use of gardens. Moreover, ground cover bamboo seedlings in the natural growth state in nurseries vary from good to bad. Excavation The expected effect cannot be achieved within 3-4 years after being used for gardening, and the construction cost is high. The groundcover bamboo seedling raising technology provided by the present invention has the advantages of fast emergence, uniform seedling growth, low cost, simple garden utilization and later maintenance and management, and high survival rate during garden utilization. Bamboo seedlings can be directly planted together with a nutritional pot.

At present, the seedling raising method of ground cover bamboo is mainly to grow seedlings in separate fields (that is, natural propagation). The seedling raising process includes site preparation, introduction of bamboo seedlings, and later maintenance and management. The problems in this kind of seedling raising method are as follows: the cost of mother bamboo seedlings is high, including bamboo seedling costs, transportation costs, and post-management costs. The cost of sales and management of finished seedlings in the late stage of field seedling cultivation is relatively high, mainly due to the excavation cost of finished seedlings, the transportation cost of finished seedlings, the later maintenance cost of finished seedlings, etc., and the growth status of finished seedlings is difficult to reach a consistent level. It will affect its scope of application in garden landscape.

At present, the survival rate of the conventional way of burying whip seedlings is low, only 37.5-57.7% (Zhou Yuqing, 2005; Wu Zhongneng, 2010), the main reason is that the seedlings are raised in seedbeds, the substrate used in the seedbeds is ordinary soil, and the seedlings are raised in seedbeds , when the finished seedlings are exported, it is necessary to dig out the seedlings from the seedbed, which will damage the root system of the bamboo seedlings and have a great impact on the survival rate of the bamboo seedlings. It takes at least 2-3 years to turn green to fully survive to have ornamental value, so the cycle is longer.

Detailed ways

The present invention is explained below in conjunction with specific embodiments.

Example 1

Ground cover bamboo industrialized seedling raising method is as follows:

Choose a flat area that is windy, sunny, convenient for transportation, and convenient for irrigation and drainage, and excavate 6 to 8 drainage ditches with a width of 30 cm and a depth of 50 cm around the seedlings and the interior to form a "field" structure to ensure smooth drainage and achieve seedlings. In the event of heavy rainfall, there should be no water accumulation in the venue.

Select loose and fertile, deep soil, rich in organic matter, and mountainous yellow soil with a pH value between 4.5 and 7.0 for soil mining. Use a hoe to sort out the fresh soil samples, and through sorting, the soil can meet the requirements of fineness and softness. Put the peat soil and the collected yellow loam into a large mixer according to different volumes, depending on different seedling bamboo species, and add KMnO ₄ and carbendazim solution to disinfect the soil, mix well, and set aside.

In the green bamboo garden with good growth conditions, excavate with a shovel along the edge of the bamboo garden (the width of the shovel head is 10-15cm×25-30cm, at the edge of the bamboo garden, there are more bamboo whips, and young bamboo whips are the most important ones. Main), dig out the bamboo whip with soil, soak it in clean water, clean the soil around the root system, do not shake off the soil with your hands, choose light yellow 2-3 years old bamboo whip with strong buds, 20-30 pieces Bundle the bamboo whips together, put them on a flat place, and cover them with licorice soaked in water to prevent the water in the bamboo whips from evaporating. When taking the required propagation materials, the scissors should be sharp, the upper and lower cuts should be smooth, and it is strictly forbidden to tear the whip section.

Fill the 10cm nutrient bowl with 1/2 of the treated culture medium in advance, spread 3 to 5 sections of propagation material on the culture medium, and then fill the nutrient bowl with the culture medium. After the substrate is filled, gently press it with the palm of your hand to make it come into close contact with the propagation material. After the cutting is completed, spray clean water into the container with a sprayer in time to carry out seedling cultivation and planting.

If seedlings are raised in winter, cover film treatment is required. First place the containers sprayed with clear water after the cuttings are completed at a distance of 100 cm, and the distance from the vault to the ground is 50 cm, and the distance from the vault to the ground is arched with bamboo chips, and then covered with a new agricultural film with good transparency, and the surrounding edges of the film are sealed with soil in time. On sunny days or when the temperature is high at noon, both ends should be left to ventilate and cool down. After cuttings, remove the film for ventilation every 2 to 3 days in the morning or evening. The spring and autumn cover film depends on the situation. After the film covering is completed or the cuttings are completed in spring, summer, and autumn, build a sunshade at a height of 1.5-2.0m above the container in time. The awning is shaded with 70% of the awning net, so that the sunlight cannot directly shine on the container in the morning and evening. After the temperature is lower than 30°C, the awning can be gradually withdrawn.
