Method for greenhouse planting of pitaya in north

Abstract

A method for greenhouse planting of pitaya in the north can realize high yield, is simple is process, and comprises the following steps: seedling raising is performed in spring, well-growing stems knots with length of 15 cm are selected to be cultivated for 15-30 days to generate roots, when the lengths of the roots reach 4 cm, the stems knots are transferred into a seed bed, wherein preferably, the seed bed can be a plot which is upwind and sunny, has fertile soil, and is convenient to realize irrigation and drainage; the plot is subjected to fine land preparation to be in a form of wows with grooves, of which depths are 90 cm, 1500-2000 kg decomposition chicken manure or cattle manure are fertilized on one acre of land, 1,000 kg rice husk ash are added, full mixed, and applied on a topsoil below 10-20 cm of the wows, and then 100-150 kg calcium phosphate fertilizer are fertilized to the land, fully stirred by a hoe, and fertilized on another topsoil with the depth of 4-5 cm; then stems knots in the seed bed are planted in the front bed according to the spacing in rows of 3 cm, thoroughly watering is performed, spraying 500 # Boshi Yeling pesticide once is performed, 5-7 kg compound fertilizer are fertilized every 10-15 days, and then the stems knots can be transferred out of the seedbed for planting after first section stems with plump stem sprouts are grown out.

Description

technical field [0001] The invention relates to a method for planting northern dragon fruit in a greenhouse. Background technique [0002] Dragon fruit is tropical, subtropical fruit, and its cultivation technique is simple. It likes to be warm and humid, and it is shade-tolerant and barren-tolerant. The optimum temperature for growth is 25-35°C, and it can be planted in the open air where the low temperature is higher than 5°C. The soil requirements are not strict, and it can be cultivated on flat land, paddy field, hillside or dry land. It grows well in fertile, well-drained neutral or slightly acidic sandy red soil or loam. It has aerial roots, strong roots, and extremely vigorous vitality. [0003] 1. Nutrient composition and economic value of fruit: [0004] Pitaya single fruit weighs 0.5-1 kg, per 100 g of fresh fruit, the ancient moisture is 82.583 grams, the fat is 0.21-0.61 grams, the protein is 0.15-0.22 grams, the fiber is 0.7-0.9 mg, the phosphorus is 20.2-26.1...
