Embodiment 1

[0040] Embodiment 1 Papaya northern greenhouse cultivation method

[0041] The concrete steps of papaya northern greenhouse cultivation method of the present invention are as follows:

[0042] 1. Plan the papaya plantation

[0043] Choose a solar greenhouse with a heating device, and it is a semi-arch circular greenhouse structure with a short back slope (100-150cm) and a high back wall (200-220cm). This structure has good lighting and large space; The thickness of the wall in the area is 80-100cm, and the thickness of the wall is 100-150cm in the area around 38-42° north latitude, and the light transmittance of the plastic film of the greenhouse is above 65%.

[0044] 2. Colonization method

[0045] Before planting, prepare the ground, dig planting holes, and improve the soil. The ground preparation is based on the level of the greenhouse floor; first dig the planting holes, then prepare nutrient soil and backfill. The specifications of the planting hole are 60-65cm in dia...

Embodiment 2

[0070] The concrete steps of papaya northern greenhouse cultivation method of the present invention are as follows:

[0071] 1. Plan the papaya plantation

[0072] Choose a multi-span greenhouse with a height of not less than 330cm. The roof is made of glass and the light transmittance is above 65%. This structure has the functions of cooling, humidifying and ventilating.

[0073] 2. Colonization method

[0074] The specifications of the planting hole are 70-75cm in diameter and 45-50cm deep; the volume ratio of the nutrient soil is peat: organic fertilizer: original soil = 2: 1: 7, and the prepared nutrient soil is backfilled into the planting hole and is 26cm above the ground. Irrigated for planting. The planting specification can adopt the row spacing of 2m×2.4m.

[0075] Use 0.3% ferrous sulfate solution to adjust the soil acidity, and control the soil pH value between 7.0 and 7.5 based on the soil being fully soaked at a depth of 28-30 cm. From April to October, it is...

Abstract

The invention relates to a system and a normative north greenhouse cultivation method of the papaya. The method comprises the following steps of: selecting a greenhouse with good thermal insulation property, adjusting the soil acidity, managing the temperature and the humidity in the greenhouse, and the like. The cultivation method is suitable for normatively cultivating the papaya in the north greenhouse, and cultivating the tropic and subtropic fruit trees by utilizing an existing greenhouse condition in the north, so that the types of the crops which are cultivated by north facilities are enriched. The papaya which is planted by the method is beautiful in tree body, beautiful in fruit shape, good in color and luster, mellow in taste, exquisite and succulent in pulp, good in mouthfeel during eating, and high in yield, thereby being suitable for touring and picking in the north greenhouse.

Description

technical field [0001] The invention relates to a method for cultivating tropical fruit trees in a northern greenhouse, in particular to a method for cultivating papaya in a northern greenhouse. Background technique [0002] Papaya is a tropical herbaceous fruit tree of the Papaya family Papaya genus. It originates in tropical America and is now distributed in tropical and subtropical regions. my country has cultivated papaya with a history of more than 300 years. At present, my country's papaya is mainly distributed in some southern provinces such as Guangdong, Guangxi, Fujian, Yunnan, Taiwan, Sichuan, and Hainan. [0003] Papaya is a typical tropical plant, which is quite different from northern plants, and has a long flowering and fruiting period. It is very popular among sightseeing and picking tourists, and has good economic benefits. Therefore, the use of northern facilities to cultivate papaya, one of the tropical fruit tree varieties with promotional prospects, will...
