Strawberry pipeline cultivation is the use of pipeline as the carrier of strawberry cultivation, the use of micro-control computers to achieve intelligent regulation of nutrient solution and temperature, light, gas, heat and other environmental factors, so that strawberries in the pipeline normal and rapid growth, flowering, fruit. It is a mode of hydroponics, greatly reducing the pests and diseases brought about by the soil, more clean and hygienic, can be cultivated in greenhouses, home balconies and indoor places, and the use of three-dimensional cultivation, improve the yield per unit area, generally up to 1,500-2,000 kilograms of production per 667 square meters.
How to choose the pipeline cultivation site
For large area pipeline cultivation, it is usually carried out in greenhouses, and for small area cultivation, it can be carried out on roofs and balconies.
How to make the cultivation frame for piping cultivation?
Pipeline cultivation of cultivation frame can be used PVC pipe, every 20 centimeters punched holes, hole size 6-10 centimeters, the general length of the pipe to 8-10 meters is appropriate, the pipeline is too long, easy to cause the end of the plant lack of oxygen. Put a good hole in the PVC has been adjusted to the level of the wooden frame, the height of the wooden frame of about 1.5 meters, easy to operate manually, the wooden frame slope of 60 °, each layer of pipeline 30 centimeters apart.
What is the role of the nutrient pool
Nutrient pool is divided into mother liquor pool and storage pool. Liquid storage pool is mainly used for pipeline nutrient solution circulation back to storage, so that the nutrient solution recycling. The mother liquor pool is mainly applied to the nutrient solution is absorbed by the plant, the micro-control computer according to the detection of its EC value, such as lower than the set value will automatically replenish the mother liquor. Nutrient solution and mother liquor pool are generally placed underground, so that it is warm in winter and cool in summer, which is favorable to the rapid growth of strawberry.
What kind of varieties are suitable for pipeline cultivation
Strawberries under pipeline cultivation are generally selected for their short dormancy period, fewer days from bud to blossom, high fruiting rate, cold tolerance, shade tolerance, and strong disease resistance.
What should be done before planting?
Greenhouse pipeline cultivation of strawberries, mainly in the spring market off-season, so it is necessary to prepare seedlings that have completed bud differentiation before freezing. One week before planting, use carbendazim and metribuzin for preventive disinfection and sterilization. Before planting, cut off the old leaves, diseased leaves, stolons, eliminate small seedlings, weak seedlings, and some rotten roots, generally in early October planting, planting with a sponge wrapped around the root neck area, stuffed into the already punched holes in the pipeline can be fixed.
How to prepare nutrient solution
Nutrient solution for strawberry cultivation can choose the whole family nutrient solution, in order to prevent precipitation when placed, generally separate the calcium and phosphorus sources, will not produce precipitation of calcium nitrate and potassium nitrate classified as a class of one ammonium phosphate and magnesium sulfate classified as a class of one ammonium phosphate and magnesium sulfate, usually divided into three categories of A, B, C. Configuration of the first 1/3 of the water, to completely dissolve the A, the cycle of uniformity, and then B dissolved and diluted to a certain degree, the first 1/3 of the water, and the second 3/3 of the water, the first 1/3 of the water, the A is completely dissolved, and then B dissolved to a certain extent. Inject slowly at the water inlet, add water while injecting, and stir constantly, and then add C liquid in the same way after the cycle is uniform, and the cycle can be uniform. (Liquid A: calcium nitrate tetrahydrate 236, potassium nitrate 303; liquid B: monoammonium phosphate 57, magnesium sulfate heptahydrate 123; liquid C: chelated iron 20-40, boric acid 2.86, manganese sulfate tetrahydrate 2.13, zinc sulfate heptahydrate 0.22, copper sulfate 0.08, ammonium molybdate 0.02)
Adjustment of nutrient solution pH value: the pH value of nutrient solution for strawberry cultivation should be kept at 5.5-6.5, which can be measured by portable pH meter and is convenient for testing. If the pH value is too high, i.e. alkaline, appropriate amount of phosphoric acid or sulfuric acid should be added to neutralize, if it is a hard water area, a mixture of phosphoric acid and sulfuric acid can be used to neutralize, and if the pH value is too low, i.e. acidic, sodium hydroxide or potassium hydroxide can be added to neutralize. 1-2 weeks is appropriate for the adjustment cycle of pH, and it is found that the pH value is unsuitable, and the adjustment is carried out in the storage tank immediately.
How to manage the electrical conductivity (EC) of the nutrient solution after planting in pipeline cultivation
1.0-1.5 mg/cm² at seedling stage; 1.5-1.8 mg/cm² at flowering and fruiting stage; 1.8-2.0 mg/cm² at harvesting stage.
How to manage the temperature after planting in pipeline cultivation?
Keep the temperature at 24℃-30℃ during the daytime before the buds appear, automatically release the wind to cool down the temperature, and keep it at 8℃-10℃ at night. During the bud stage, the daytime temperature is kept at 25℃-28℃, and the nighttime temperature is kept at 8℃-12℃. During the flowering period, keep the temperature at 22℃-25℃ during the day and 8℃-12℃ at night. If the flowering period experiences low temperature below -2℃, the phenomenon of stamen anthers turning black and pistil stigma discoloration will occur, which will seriously affect the pollination and fertilization and the yield of strawberry in the early stage. Fruit expansion and ripening period of daytime temperature to maintain 20 ℃ -25 ℃, night 8 ℃ -12 ℃. The temperature is too high in this period, the fruit expansion is affected, resulting in fruit coloring fast, ripening early, but the fruit is small, poor quality.
How to manage humidity after planting in pipeline cultivation
During the flowering period, the humidity in the greenhouse should be controlled at 40%-50%, and higher than 50% should be ventilated in time.
How to control supplemental light in pipeline cultivation
Strawberry’s growth temperature is 15℃-25℃, belongs to the light-loving plants, short sunshine less than 12 hours to promote flower bud differentiation, dormancy and dwarf plants, long sunshine to promote its growth and development.
Intelligent intermittent replenishment of light in mid-November – January to promote the nutritional growth of strawberries, replenishment of light is best used to replenish red plant replenishment light to improve the efficiency of its photosynthesis.
How to spray page fertilizer for piping cultivation
Throughout the normal process of strawberry, generally every 7-10 days to spray 1 time 0.2%-0.5% urea and potassium dihydrogen phosphate, pre-growth to urea-based, late flowering to potassium dihydrogen phosphate-based.
Pipeline cultivation how to artificial pollination
Strawberries are self-pollinating plants, but heterogamous pollination can significantly improve yield and quality. Through the release of bees, flowering ventilation, artificial insemination and varieties with cultivation and other measures to increase the probability of heterogamous pollination. Generally per 667 square meters of solarium put 1-2 boxes of bees, the total number of bees in 10,000-20,000, to ensure that a strawberry plant has more than one bee, can also be used in the morning after 10:00 am in the open flowers on the paint a few times, so that the pollen in the open stamen evenly sprinkled throughout the receptacle, or fan fan the flowers on the plant and other ways can be auxiliary pollination.
How to thin flowers and fruits in pipeline cultivation
During the reproductive period of strawberries, old and diseased leaves should be removed in time to facilitate ventilation and light penetration, so that the plants are exposed to uniform light. A strawberry plant has 2-3 inflorescences, each inflorescence has 5-30 florets, in order to ensure that the fruit is large and neat, before the first floret opens to thin out part of the flower buds, each inflorescence left 10-12 flowers. When the fruit is found to be red, harvest it in time, and harvest it once a day.
How to control pests and diseases in pipeline cultivation
Strawberry pipeline cultivation is rarely disease, such as the discovery of diseased leaves, diseased plants should be removed in a timely manner, and sprayed with carbendazim or metribuzin German fungicide for sterilization and prevention.
