Problems solved by technology

However, the pH of the base of vinegar residue is mostly around 6.0, the pH of the base of mushroom dregs is mostly between 7.5-7.8, and strawberries are only suitable for growing in neutral or slightly acidic soil environments. Therefore, the pH shows that neither of them is suitable for strawberries alone. Cultivation medium

Embodiment Construction

[0018] The implementation site is in the Venlo-type multi-span glass greenhouse of the Agricultural Engineering Research Institute of Jiangsu University. The cultivation frame unit is composed of a steel frame and PVC pipes supported by it. Layer 1 trough, 6m long, 1.0m wide at the base of the cultivation frame. Each planting frame unit covers an area of ​​6m 2 . The upper opening of the PVC pipe is 10cm to fill the substrate and cultivate strawberries.

[0019] In mid-August 2012, the purchased straw mushroom residue matrix and vinegar residue matrix were mixed uniformly and sprinkled with water at a volume ratio of 3:2. After the maximum water holding capacity of the composite matrix reached 75%, they were piled up and covered with film for 2 Days later, turn it over again, sprinkle water once, and after the film is left to stand, the composite matrix bulk density is measured to be 0.26g / cm 3 , total porosity 68.6%, available potassium content 10.12g / kg, organic matter co...

Abstract

The invention discloses a light organic matrix preparation method for a strawberry cultivation frame and a matching fertilizing method. The light organic matrix preparation method for the strawberry cultivation frame comprises the steps: mushroom dregs and vinegar residue matrix are mixed, wherein the volume ratio of the mushroom dregs and the vinegar residue matrixes is 3:2, the mixed material is stirred circularly, water is sprayed on the mixed material, the mixed material stands, and finally light organic matrix is obtained, wherein the volume weight of the light organic matrix is 0.25-0.28g/cm<3>, the total porosity of the light organic matrix is 65-79%, the content of available potassium is 9.8-10.2g/kg, the content of available nitrogen is 0.9-1.0g/kg, the content of available phosphorus is 0.29-0.32g/kg, the EC value of the light organic matrix is 1.0-1.3mS/cm, and the PH value of the light organic matrix is 6.7-7.0. By means of a matching fertilizing technology in the cultivation process of strawberries, 42.4kg strawberries can be harvested in total on one cultivation frame unit which occupies a 6 m<3> area place, the yield of the strawberries is increased greatly, and the light organic matrix preparation method and the matching fertilizing method can be applied to strawberry cultivation.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency protected agriculture, and in particular relates to a method for preparing a protected cultivation substrate and a matching fertilization technology in the cultivation process. Background technique [0002] With the rapid development of my country's efficient agriculture, strawberry, known as the "Queen of Fruits", has been further promoted throughout the country. At present, my country's planting scale has exceeded 120,000 hectares, with a total output of about 2 million tons and an annual export of more than 100,000 tons of strawberries. It has become the world's largest strawberry production, processing and exporting country. However, in terms of planting methods, my country still mostly uses traditional open field or vertical cultivation in sheds, which has serious obstacles to continuous cropping and cannot meet the requirements of clean production. As a result, the yield and quality ...
