Embodiment 1
[0021] 1. Afforestation site selection and site preparation
[0022] Choose convenient transportation, slope less than 25 degrees, altitude below 900m, low hills, plains, along the banks of alluvial streams, tidal flats and open spaces in front of and behind houses. The land is deep loose, fertile and moist, slightly or neutral sandy soil, with a pH value of 4.5-7.0 and well-drained areas;
[0023] Yellow sweet bamboo is a medium-sized bamboo that grows loosely, and the shoots of yellow sweet bamboo become forests, mainly relying on the growth of underground whips. The afforestation of yellow sweet bamboo generally adopts full reclamation and land preparation. Before afforestation, first split the mountain, remove weeds, shrubs, tree stumps, stones and other objects in the garden, cultivate the land about 30cm deep, and dig holes according to the number of planned plantings. Specifications: 80×50×40cm. Apply 0.5kg of compound fertilizer or 5-10kg of decomposed farmyard manur...
Embodiment 2
[0034] The mother bamboo garden is located in the Baiguoyuan base of Lishui Forestry Science Research Institute, which belongs to the low mountain and hilly area in southwestern Zhejiang, with an average altitude of 140m and an average slope of 25°. The soil is red soil with a pH value of 5.1. The afforestation time is from February to March.
[0035] Mother bamboo A: select diameter 2-3cm, 1-2 year life, the yellow sweet bamboo that grows vigorously is mother bamboo, see embodiment 1;
[0036] Mother bamboo B: On the basis of mother bamboo A, the mother bamboo is first treated as follows:
[0037] (1) before transplanting, the incoming whip and the removed whip of mother bamboo are cut off, the incoming whip is reserved for 25-30 cm, and the removed whip is reserved for 30-45 cm, and the cutting time is August-September;
[0038] (2) digging a depth of 30cm, an annular groove of width 20cm around the cutting place of mother bamboo to cut off the whip and remove the whip, app...

Abstract
The invention relates to a long-distance introduction and afforestation method of acidosasa edulis, which belongs to the technical field of production of forestry. The long-distance introduction and afforestation method mainly comprises the steps of selection of afforestation land, land preparation, selection of parent bamboos, planting and management of a bamboo garden, and is characterized by selecting the acidosasa edulis which are in diameter of 2-3cm, 1-2 years old and robust in growth as the parent bamboos, and the parent bamboos need to be processed as follows: (1) cutting off incomingroots and outgoing roots of the parent bamboos before transplanting, retaining the incoming roots by 25-30cm, and retaining the outgoing roots by 30-45cm, wherein the time for cutting off is between August and September; (2) digging an annular groove with the depth of 30cm and the width of 20cm around each parent bamboo in the position wherein the incoming roots and the outgoing roots of the parent bamboo are cut off, and applying an organic fertilizer in each groove; and (3) digging up the parent bamboos together with original soil along the annular grooves when the parent bamboos are transplanted, and retaining 4-6 circles of branches after digging up the parent bamboos. According to the method disclosed by the invention, the survival rate and the number of bamboo shoots of afforestation of the acidosasa edulis are significantly improved, and the method can be suitable for long-distance transportation, introduction and cultivation and has very high popularization value.
Description
technical field [0001] The invention relates to the technical field of forestry production, in particular to a method for long-distance introduction and afforestation of yellow sweet bamboo with high afforestation survival rate. Background technique [0002] Yellow sweet bamboo (Acidosasa edulis (Wen) Wen), belongs to Gramineae (Gramineae) Bamboo subfamily (Bambusoideae) Acidosasa (Acidosasa), also known as Huangjian bamboo, rhizomes with multiple axis type, culm height 8-12m. The bamboo shoot period is from mid-April to early June. The bamboo shoot period is early, the bamboo shoot period lasts for a long time, and the bamboo shoot rate is high. The bamboo shoots are of high quality, delicious and sweet. [0003] Yellow sweet bamboo has high development and utilization value. In terms of economic value, after being cultivated and survived, yellow-sweet bamboo has a high yield and a large profit. Due to the delicious taste of yellow-sweet bamboo shoots, the shooting period ...
