Plug substrate rainproof strawberry seedling culturing method and special facility

Abstract

The invention provides a plug substrate rainproof strawberry seedling culturing method and a special facility, belonging to the strawberry breeding technology. The method is characterized by comprising the following steps: A. setting up a special shed frame facility, arranging a seedling platform, appressing and covering a permeable nonwoven on substrates in plugs and horizontally arranging a weeping pipe and control valves on the nonwoven at intervals; B. planting parent seedlings and controlling the water content of the substrates at the roots; C. when stem buds on creeping stems of the parent seedlings grow to have two leaves and one core, cutting the permeable nonwoven which is close to the stem bud part and is appressed and covered on the substrates in the plugs, planting the stem buds in each plug by passing through the cut and controlling the water content of the substrates at the roots; and D. when the seedlings continuously grow to the seedling age, namely 30-40 days, controlling the water content of the substrates at the roots to be 10-15% and obtaining annual seedlings when the seedlings grow to have four complete leaves and the external diameters of the dwarf stems are not less than seven millimeters. The method and the special facility have the following beneficial effects that: the annual seedlings are prevented from being infected with diseases and suffering from weeds; water is uniformly supplied and saved; and the water content of the seedlings is effectively controlled and the seedlings are promoted to be ripened more than one month earlier.

Description

technical field [0001] The invention belongs to strawberry seedling raising technology, in particular to a strawberry plug-in substrate rain-proof seedling raising method and special facilities. Background technique [0002] Strawberry seedling raising is an important part of strawberry production. As the saying goes, "70% of the harvest is good for seedlings". At present, strawberry seedling cultivation mainly adopts a relatively simple and extensive method of bare root seedling cultivation in the open field. This method is more suitable for European and American varieties with strong disease resistance. However, with the improvement of people's requirements for the quality of fresh strawberries, the planting area of ​​high-quality varieties from Japan has increased year by year, but "most of the high-quality varieties in Japan have poor heat resistance and waterlogging resistance, and are prone to anthracnose and blight in hot and rainy summers." and many other diseases....

Problems solved by technology

[0007] 3. For the seedlings planted in the plug trays with an inclination angle of 75-85 degrees, use the nozzle to supply water from the bottom of the plug tray or spray the seedlings from the top to supply water or culture solution, which can neither achieve the goal of cultivating the matrix in all the plug trays. The uniform water supply or culture solution for the roots of neutron seedlings cannot achieve the effect of saving water or culture solution

[0008] 4. Just because it is impossible to evenly and reasonably replenish water to the roots of the seedlings, it is impossible to control the water content in the matrix around the roots of the seedlings during the growth process, and it is difficult to cultivate strong strawberries with high yield and premature birth.
