有机生态型无土栽培技术,是指不用天然土壤而使用基质,不用营养液浇灌植物根系而使用有机肥和固态化肥并直接用清水浇灌作物的一种无土栽培技术。它把有机农业导人无土栽培,同时实行有机与无机结合,形成生态型无土栽培农业。 1 适合有机生态型基质的配制 有机生态型基质,原料资源丰富易得,处理加工方便,就地取材。如:玉米、大豆、花生粉碎的秸秆、锯末、刨花等,都可按一定比例混合使用。为调整墓质的物理性质,可加入一定量的无机物,如:蛭石、珍珠岩、炉渣、河沙等,加入量依调整需要而定,一般有机物与无机物之比按体积计算在2～8∶8～2间;要求混后的基质容重在0.3～0.6克/厘米~3 Organic soilless cultivation technology, refers to the use of natural soil matrix, without nutrient solution watering plant roots and the use of organic fertilizers and solid fertilizers directly irrigated crops with a soilless culture technology. It introduces organic agriculture into soilless cultivation, and at the same time practicing organic and inorganic combination to form eco-type soilless cultivation agriculture. 1 for organic ecological matrix preparation organic ecological substrate, raw materials rich in resources, processing and processing convenience, local materials. Such as: corn, soybeans, peanuts crushed straw, sawdust, shavings, etc., can be mixed by a certain percentage. In order to adjust the physical properties of the tomb, a certain amount of inorganic substances may be added, for example, vermiculite, perlite, slag, river sand and so on. The addition amount may be adjusted according to the requirement of adjustment. Generally, ~ 8: 8 ~ 2; the matrix of the required mixed bulk density of 0.3 ~ 0.6 g / cm ~ 3
