Pineapple varieties and their practical production techniques

1. Excellent varieties

(1) Australian cocaine

The plant height is 90mm 120 cm, the leaf is wide and thick, there are 2-8 receptacle buds, 4 buds are absorbed, and the germination is late. The budding period is February. Flowering period from late March to early April. The fruit is long cylindrical, the average fruit weight is 2 kg, the maximum fruit weight is 2.8 kg, the pericarp is orange, the small fruit is large, the bracts are flat and the fruit eyes are shallow. Yellow pulp, more fruit juice, less fiber, soft pulp, soluble solids content of 12.3%-14.5%, is an excellent variety of fresh food and processing. The ripening period of positive fruit is from July to August, which belongs to the late-maturing variety.

(2) Yue Crispy Pineapple

The plant is tall, with a height of 87cm and 102 cm, and each plant has 1 bud absorption. In Guangzhou, the budding period is from late March to early April, and the flowering period is from late April to early May. The single fruit weighs about 1.5 kg and the maximum is 3.5 kg. The flesh is yellow, the flesh and core are crisp, the fiber is less, the aroma is strong, the edible taste is better, the soluble solids content is 15.2%, and the fresh fruit quality is better than that of Bali. The processing character was better than that of Cain. The mature period of mid-late August was about 30 days later than that of Bali and 7-10 days later than that of Cain.

2. Key points of cultivation techniques

The main results are as follows: (1) choose qualified, disease-free and pest-free high-quality seedlings and plant robust seedlings with a height of more than 30 cm.

(2) reasonable close planting, generally planting 2500 to 3000 plants per mu, and the row spacing is 0.35 m × 0.40 m.

(3) the cultivation and management was carried out according to the cultivation standard of pineapple.

(4) the annual supply can be realized by the technology of florescence regulation. When the number of 50 cm long green leaves is more than 40, flowering can be promoted, usually from August to October. Guangdong crisp uses ethephon 800 times solution, each plant infuses 50 ml; Australian caine uses ethephon 500 times liquid to add 1% urea, each plant infuses 50 ml, 7 days later according to the same method to urge the flower again.

(5) tissue culture and rapid propagation of seedlings with stem tips to speed up the speed and quality of seedling breeding.
