运用回归设计方法，研究了茄果类育苗基质的配方施肥。在使用１∶１的紫色菜土与渣肥的混合物时，番茄和辣椒的育苗基质分别每立方米配施０．６ｋｇ和０．９５ｋｇ尿素、２０ｋｇ和１０ｋｇ过磷酸钙、０～１２ｋｇ和１．２～３．０ｋｇ硫酸钾，可使幼苗生长旺盛，植株健壮。而茄果类育苗的通用基质，则以配施０．６ｋｇ／ｍ３尿素、１０ｋｇ／ｍ３过磷酸钙和０～１．２ｋｇ／ｍ３硫酸钾为好。 Regression design method was used to study the formula fertilization of eggplant nursery substrate. In the case of a 1: 1 mixture of purple vegetable soil and residue fertilizer, the nursery substrate for tomato and pepper are dispensed 0.6 kg and 0.95 kg of urea, 20 kg and 10 kg of superphosphate, 0-12 kg and 1 per cubic meter, respectively. 2 ~ 3.0kg potassium sulfate, seedlings can make vigorous growth, robust plants. The solanaceous seedling of the common matrix, then the allocation of 0.6kg / m3 urea, 10kg / m3 superphosphate and 0 ~ 1.2kg / m3 potassium sulfate is better.
