Embodiment 1
[0036] Rapid Propagation of Cuttings of Alum Root Variety 'Mamaredu'
[0037] 1 Female parent nursery construction and female parent management
[0038] 1.1 Construction of female parent nursery
[0039] Set up alum root female ear picking nursery in a well-ventilated plastic greenhouse that is not easy to accumulate water. The greenhouse has a span of 8 meters, a bay of 4 meters, and a shoulder height of 4 meters. A layer of shading nets with a shading rate of 50% that can be manually opened and closed is installed inside. , The ground of the greenhouse is covered with black ground cloth to prevent the growth of weeds. A drainage ditch with a depth of 30 cm and a width of 40 cm is set every 8 meters (each span) on the ground of the greenhouse. The bottom of the drainage ditch is provided with a 3% slope to facilitate the drainage of accumulated water. The temperature in the plastic greenhouse with the shading rate controlled at 50% is between 6 and 35°C, the highest temperat...
Embodiment 2
[0055] Cutting Rapid Propagation of Example 2 Alum Root Variety 'Plum Pudding'
[0056] Embodiment 2 is the same as Embodiment 1 except that the following measures are different, and will not be repeated here.
[0057] 1.2 Maternal management
[0058] A. The female parent of alum root 'plum pudding' is planted in 6L (pot diameter 23cm, pot height 18cm) PP flower pots, and the density of flower pots is 3800 pots / mu. The cultivation substrate is formed by mixing coconut bran, peat and perlite according to the volume ratio of coconut peat: peat: perlite is 2:1:0.2, the pH value of the cultivation substrate is 6.0~6.5, and the EC value is 1.3~1.5 ms / cm.
[0059] B. The amount of controlled-release fertilizer topdressing the female parent of alum root 'plum pudding' every 6 to 8 months is 16g / pot.
[0060] 2.2 Preparation before cutting
[0061] The cutting matrix is composed of coconut bran, peat, vermiculite and perlite in a volume ratio of 3:1:0.5:0.2 of coconut bran: peat...
