Method for soilless culture of elevated strawberries

Abstract

The invention discloses a soilless culture method for elevated strawberries. The soilless culture method comprises the following steps that the strawberries are cultivated in a greenhouse through a soilless culture elevated frame; the soilless culture elevated frame comprises a culture frame, a matrix net bag, a drip irrigation pipe, a black and white film and a fluid director. The cultivation frame comprises an H-shaped framework and supporting pipes. A breathable non-woven fabric and a nano film are cushioned at the bottom of the inner side of the substrate net bag; the two drip irrigation pipes are arranged close to the front edge and the rear edge of the matrix net bag respectively, and drip irrigation openings are formed in the lower sides of the drip irrigation pipes. The black and white film covers the matrix net bag and the drip irrigation pipe; the fluid director comprises a U-shaped groove plate and a water absorption strip; the upper half parts of the two U-shaped groove plates are respectively clamped on the two drip irrigation pipes and are positioned under the drip irrigation openings; the lower half parts of the two U-shaped groove plates form an accommodating cavity; the two ends of the water absorption strip extend into the containing cavities in the lower half portions of the two U-shaped groove plates respectively, and the middle of the water absorption strip is buried in the culture medium. Water and fertilizer can be uniformly supplemented to strawberry plants, water, fertilizer and pesticide are saved in the whole production process, labor can be saved, and labor intensity is reduced.

Description

technical field [0001] The invention belongs to the technical field of strawberry cultivation, and in particular relates to a soilless cultivation method for elevated strawberries. Background technique [0002] Strawberries are beautiful in appearance, rich in nutrition, and have a sweet and sour taste. They are very popular among consumers. The cultivated area of ​​strawberries is increasing year by year. The planting area has reached more than 2.3 million tons, and the total output has reached more than 4 million tons, accounting for 35.21% and 41.7% of the world's strawberry planting area and output respectively. The total output value has exceeded 60 billion yuan, becoming the world's largest country in strawberry production and consumption. . [0003] At present, more than 90% of strawberries in my country are mainly cultivated on the ground. This kind of strawberry cultivation method requires workers to bend over frequently during the cultivation process, especially t...

Problems solved by technology

[0003] At present, more than 90% of strawberries in my country are mainly cultivated on the ground. This kind of strawberry cultivation method requires workers to bend over frequently during the cultivation process, especially when bending over 45°, which makes the labor intensity particularly high. , After working for a long time, the laborer will have a sore waist and backache, and have to slow down the operation speed or stop frequently to rest, which will reduce the labor efficiency, increase the labor time, and increase the labor cost, which affects the strawberry production. In addition, there are still problems such as serious continuous cropping obstacles in ground cultivation, and these problems also affect the income of strawberries.

In order to overcome the above problems, the technology of elevated soilless cultivation of strawberries is being applied more and more. Elevated soilless cultivation of strawberries refers to the use of supports to erect the culture tanks in the air, and then put the culture medium into the culture tanks to plant strawberries. Strawberry planting technology needs to overcome the problem of water and fertilizer replenishment in the planting process. The current water and fertilizer replenishment in soilless cultivation is usually realized by two drip irrigation pipes, but in the drip irrigation process, there are the following problems: Many growers install the drip irrigation pipes in the wrong place , or the two drip irrigation pipes are installed too close to the strawberry plants, so that the soil on both sides of the strawberry plants is completely covered by the drip irrigation pipes, affecting the ventilation of the strawberry roots, and it is easy to cause the water content near the strawberry plants to be too high, and the culture medium is breathable or the drip irrigation pipe is installed too far away from the strawberry plants, so that during the drip irrigation process, most of the water and fertilizer have penetrated into the bottom of the culture tank before they penetrate into the strawberry plants and are fully absorbed by the strawberry plants , causing the strawberry plants to lack nutrition in the early stage, resulting in too slow growth, and a large amount of water and fertilizer concentrated at the bottom of the culture tank, which leads to excess concentration of substances in the water and fertilizer at the bottom of the culture medium, which may cause root burning and further affect the growth of strawberry plants
