Method of raising seedlings by hardwood cuttage for Broussonetia papyrifera

Abstract

The invention discloses a method of raising seedlings by hardwood cuttage for Broussonetia papyrifera. According to the technical scheme, the method comprises 8 steps: (1) Stems with axillary buds which are swollen and waiting to germinate in the middle and upper part of maternal branches are clipped in May as cutting materials and the thickness of the stems should be one centimeter above. (2) The cutting materials are cut into cuttings with a length of 14 to 16 centimeters and 3 or more axillary buds are required. (3) The lower part of 1.5 to 2 centimeters of the cuttings is dipped in 120ppmABT number 1 rhizogenous powder solution for 1.5 to 5 hours. (4) A cutting substrate and a seedling bowl are sterilized by disinfectant on the day before cutting. (5) The dipped cuttings are inserted into the substrate of the seedling bowl with a depth of 2 to 3 centimeters. (6) The substrate is kept moist and thoroughly watered at one time while watering and water seepage from a drain hole at the bottom of the seedling bowl is taken as a standard. (7) After cutting and rooting, the quick-acting fertilizer is applied to the substrate once every 7 to 10 days. (8) When roots wind well, the cuttings should be transplanted. The method of raising seedlings by hardwood cuttage for Broussonetia papyrifera not only has high cuttage rooting rate, but also has high rooting quality. Rooting and shooting are synchronized, which is beneficial to early growth and rapid development.

Description

technical field [0001] The invention relates to the field of forest tree cultivation, in particular to a method for raising seedlings by cutting hard branches of eucalyptus glabra. Background technique [0002] Guangyechu is a new species of mulberry tree introduced from Japan, which belongs to the genus of mulberry tree in the family Moraceae. This tree species has four characteristics: First, it has strong adaptability, resistance to drought, salt and alkali, and barrenness. Second, the growth cycle is short, planted in the same year and harvested in the same year. . Third, the benefit period is long, planted in one year and harvested in many years. Fourth, the whole body is full of treasures, and each makes the best use of it. The bark fiber is white and slender. It is a high-grade papermaking and textile raw material with high value and large market demand; wooden poles are good raw materials for the production of ordinary paper and fiberboard; leaves contain Rich in...

Problems solved by technology

Compared with tissue culture and twig cutting seedling raising methods, the hard branch cutting seedling raising method has the obvious advantages of simplicity and low cost, but the low rooting rate of hard branch cuttings is a problem that plagues the industry
