Embodiment Construction

[0018] To cultivate the reticulated muskmelon variety "Chunli" of the Institute of Horticulture, Shanghai Academy of Agricultural Sciences, the following examples are provided in conjunction with the contents of the present invention:

[0019] 1. Seedling cultivation: adopt 72-hole plug trays, perlite: vermiculite = 1: 1 formula substrate for seedling cultivation, sow on August 12, 2004.

[0020] 2. The greenhouse used is a greenhouse imported from the French Richal Company, with a single span width of 8m and a length of 60m. Each span is arranged with 4 rows of cultivation tanks with a spacing of 1.6m.

[0021] 3. Substrate selection: Special horticultural substrates produced by Shanghai Sunqiao Modern Agricultural Technology Co., Ltd. using mushroom residues and fermented chicken manure are required.

[0022] 4. Drip irrigation device discharge: The drip irrigation device is a drip irrigation pipe with a 40cm spacing inlaid with a drip head, and two tubes are installed on ea...

Abstract

The present invention relates to an ultra thin layer matrix soil less culture method. Said invention adopts solid, liquid and gas three-phase reasonable distribution and regulation technique in the soil-less culture, and said technique includes the following measures: setting nutrient liquor flow-guiding and root system guiding channel in the bottom portion of culture channel; between polyphenylene plastics and matrix abutted place forming a thin layer with rich liquid and gas two phases to guide crop root growth and make said root system be extended into upper matrix to reduce matrix thickness; and remaining a layer of nutrient liquor in the bottom portion of culture channel, said nutrient liquor can be provided for crop root system, and can be used for moistening upper layer matrix to create suitable environment for root growth. Said invention is suitable for soil-less culture of vegetables and flower.

Description

technical field [0001] The invention relates to a method in the technical field of agricultural planting, in particular to an ultra-thin layer matrix soilless cultivation method. Background technique [0002] There are many forms of soilless cultivation, such as nutrient liquid film technology (NFT), deep liquid flow cultivation technology (DFT), floating plate capillary technology (FCH) in hydroponics, etc., which are all applied in production; It is a very important kind of soil cultivation technology, which has become the main form of soilless cultivation production. More than 95% of Dutch vegetable soilless cultivation is matrix soilless cultivation. Most of the 300 hectares of soilless cultivation area in my country are also Soilless cultivation as substrate. At present, cultivation techniques such as brick-built simple groove cultivation, ordinary groove cultivation, open substrate bag cultivation, pillow substrate wrapping cultivation, potted plants, and organic ecolog...
