[0036] Example Guava cultivation method in northern greenhouse

[0037] 1. Planning the guava plantation

[0038] Choose a solar greenhouse or a heated greenhouse as a guava plantation. The structure of the greenhouse is required to be a semi-arch circular structure with a short back slope and a high back wall; the thickness of the greenhouse wall is required as follows: the thickness of the soil wall is 90cm in the area at about 35°north latitude, and the thickness of the wall is about 40°at the north latitude 140cm, to ensure that the minimum temperature in winter is above 5°C, and the winter temperature of the heating greenhouse is 15 to 35°C; the greenhouse plastic film requires a lig...

Abstract

The invention provides a method for systemically and normatively planting guavas in a greenhouse in the north. The method comprises the following steps: selecting a sunlight greenhouse or a warming greenhouse with good thermal insulation property and carrying out field planting, field management and maternity regulation and control and the like. The method is suitable for normatively planting guavas in the greenhouse in the north and planting fruit trees in torrid zones and subtropical zones by utilizing the prior greenhouse conditions to enrich the varieties of crops planted by north facilities. The guava planted by adopting the method has thick and wide leaves, attractive fruit appearance, fresh and sweet fruity flavor, good fruit color and luster, juicy and crisp pulp, good mouthfeel and high yield. The method also can regulate and control the harvest time of guavas to satisfy the demands of sightseeing picking, thereby improving the economic benefit.

Description

technical field [0001] The invention relates to a method for cultivating fruit trees, in particular to a method for cultivating guava in a northern greenhouse. Background technique [0002] Guava belongs to the woody fruit tree of the Myrtaceae Guava genus. It is native to tropical America, and the main production areas are now in India, Brazil, Mexico and South China. It is easy to cultivate, has early fruit and high yield, high nutritional value, and can adjust the production period through technology. It has become one of the emerging tree species in the southern fruit industry. In 2003, the Beijing Agricultural Technology Extension Station introduced guava seedlings and successfully planted them in a greenhouse in the suburbs of Beijing. In the north, due to its novelty, high nutritional value, and long picking time, guava is welcomed by various parks, and the cultivated area is increasing year by year. Although the research on guava cultivation technology in the south...
