瓜叶菊采用无土栽培(注:由于本栽培中使用了有机质,因此不算真正的无土栽培,只是土壤栽培的一种改良),不会出现土壤栽培时易产生的环境污染、虫蝇滋生等现象,而且花大色艳,花期延长。一.栽培基质适宜作无土栽培的基质很多,有陶粒、珍珠岩、蛭石、泥炭、河沙、锯末等。经对比试验,采用蛭石与泥炭的混合物(1:1)为好。二.营养液我们用的是本课题组自制的通用型营养液。经对比试验,用该营养液培育的花卉,性状优于波斯特营养液和国内标准营养液。其配方如下—— Cineraria soilless cultivation (Note: Since the cultivation of organic matter used, it is not a true soilless culture, but an improvement of soil cultivation), does not appear when the soil is easy to produce environmental pollution, insect breeding And so the phenomenon, but spend large color Yan, flowering extension. I. Cultivation substrate suitable for soilless cultivation of many substrates, with ceramsite, perlite, vermiculite, peat, sand, sawdust and so on. The comparative test, the use of vermiculite and peat mixture (1: 1) is better. Two. Nutritional fluid We use is the group’s self-made universal nutrient solution. After the comparative test, the flowers cultivated with the nutrient solution have better traits than Post nutrition liquid and domestic standard nutrient solution. The formula is as follows -
