Embodiment 1

[0056] Soilless Cultivation Method of Blueberry in the Open Field

[0057] S1. Seedling selection: choose 2-3 year old cutting seedlings or tissue culture seedlings, which require the seedlings to be robust, with good root systems and no pests and diseases;

[0058] It is recommended to choose varieties that are difficult to cultivate in the field but have good quality;

[0059] S2. Selection of soilless substrate: mainly coconut peat; or, use coconut peat plus appropriate amount of vermiculite or other inorganic substances, such as quartz sand;

[0060] S3. Selection of planting pot or planting tank: the size of the planting pot is 20-30 liters, and the width and depth of the planting tank can be set to 30-40cm;

[0061] S4. Seedling planting

[0062] (1) Planting time: The bare-root seedlings should be in the deciduous period of the seedlings, and the time is from late November to early March; potted seedlings can be carried out from January to December;

[0063] (2) Dens...

[0085] Effects of fertilizer and water management and selection of nutrient solution on blueberry fruit during soilless cultivation under greenhouse conditions

[0086] Using conventional greenhouse soilless cultivation techniques, select blueberry "Anna" 3-year-old plants for cultivation and management. The nutrient solution used in the fertilizer and water management uses fertilizers with different NPK contents and the same application concentration to observe the effects of different fertilizers on the growth and development of blueberries .

Abstract

The invention discloses a method for soilless cultivation of blackberries or blueberries under an open field condition. According to the method for soilless cultivation of the blackberries or the blueberries, selected nursery stocks are subjected to nursery stock fixed planting with a soilless medium, are directly placed in a field and are subjected to cultivation management under the open field condition; after fixed planting of the nursery stocks, cultivation management under the open field condition comprises the following fertilizer and water management: a fertilizer-water integrated dripirrigation technology is adopted, the ratio of NPK (nitrogen, phosphorus and potassium) in a nutrient liquid is 1:1:1, and fertilization times every day are distinguished according to different seasons; and meanwhile, in a raining period, drip irrigation fertilization is not implemented, and the concentration of the nutrient liquid applied after raining is adjusted according to rainfall. By exploring different steps of soilless medium cultivation in an open field, a set of cultivation method which is most applicable to soilless mediums and open field cultivation modes is obtained, and the maximum economic yields and economic benefits can be obtained under a condition that the cost is effectively reduced.

Description

technical field [0001] The invention belongs to the field of agricultural production, and in particular relates to a method for soilless cultivation of blackberries or blueberries under open field conditions. Background technique [0002] Soilless cultivation technology is a new agricultural production system that has developed rapidly in recent years. It uses nutrient solution to provide nutrients for crops. It has the advantages of effectively avoiding soil continuous cropping obstacles, spreading soil diseases and insect pests, and improving soil utilization. It is receiving more and more attention. Follow and study. In order to facilitate operation and control, in the current modern agricultural production, soilless cultivation is carried out under the conditions of greenhouses and other facilities, and has achieved very high economic output and economic benefits. However, the investment in greenhouses is high, ventilation and cooling are required in summer, and heating...
