specific Embodiment approach 1

[0014] Specific implementation mode 1: This implementation mode is a cranberry overwintering method using frozen crop stalks to prevent cold, specifically carried out according to the following steps:

[0015] 1. Cover crop straw: monitor the temperature in late autumn and early winter, and cover the cranberries with corn straw or rice straw when the temperature is lower than 0°C for 3 consecutive days, and the straw covering is divided into two steps;

[0016] When covering corn stalks, cover 10cm of corn stalks for the first time, and cover 20cm of corn stalks for the second time one week later;

[0017] When covering rice straw, cover rice straw 10cm for the first time, and cover rice straw 10cm for the second time one week later;

[0018] When covering the straw, it is required that the direction of the straw is consistent, the arrangement is neat, and the thickness is uniform;

[0019] 2. Irrigation and freezing: After the straw covering in step 1 is completed, water can...

Abstract

The invention discloses a cranberry overwintering method by freezing crop straws for cold protection, relates to a cranberry overwintering method, and aims at solving the technical problem that branches and tendrils of the cranberry are damaged since an existing cranberry overwintering method employing flooding and freezing cold protection requests that a cranberry pond ridge needs to have enough height and strength, premature ice snow melting easily appears in the areas with frequent high winds and relatively large temperature changes in spring, and water loss of a plant is fast. The cranberry overwintering method comprises the following steps: (1) crop straw coverage; (2) watering freezing; (3) timely removal of the straws in the next spring; and (4) recovery of normal field management. The cranberry overwintering method disclosed by the invention is applied to overwintering of the cranberry.

Description

Technical field: [0001] The invention relates to a method for overwintering cranberries. Background technique: [0002] Cranberry is a highly active and functional small berry with very high medical and health value. At present, it is mainly planted in the ecologically suitable areas of acidic peat soil in the cool regions of the northern hemisphere. Cranberry is a perennial plant, and its normal growth, flowering and fruiting requires a cooling capacity of 800 hours and a low temperature of less than 7.2°C. Flood irrigation and freezing in winter is a common way for cranberries to overwinter. That is, before winter, cranberry fields are flooded with water according to the weather conditions. The irrigation depth reaches 50cm or even 1m, and then freezes naturally until the next Thaw in the spring of each year to prevent frostbite on the vines and buds. The problems of this overwintering method are as follows: first, the cranberry field pond must have sufficient height and...
