中药渣有机基质配比对辣椒生长及产量、品质的影响

Effects of Herbal Residues Organic Substrates on Growth,Yield,and Quality of Capsicum

以中药渣、泥炭、蛭石、珍珠岩为供试材料,对中药渣有机基质进行复配改良,研究了各基质的理化性质,及其对辣椒生长发育、光合特性及品质的影响。结果表明,T2(中药渣:泥炭:蛭石=2:1:1)处理效果最好,其次为T3(中药渣:泥炭:蛭石=1:1:1)处理和T5(中药渣:泥炭:珍珠岩=2:1:1)处理。这3个处理均明显优于对照,是较为理想的无土栽培基质,生产上可代替泥炭。

Herbal residues, peat, vermiculite, and perlite were selected to prepared mixed substrates, to study physical and chemical properties of the substrates and their effects on growth, yield, quality and photosynthesis of capsicum. The results showed that the effect of treatment T2 （herbal residues ： peat ： vermiculite = 2 ： 1 ： 1 ） was the best, the next were T3 （ herbal residues ： peat ： vermiculite = 1 ： 1 ： 1 ） and T5 （ herbal residues ： peat ： perlite = 2 ： 1 ： 1 ）. These three treatments were all superior to control. Therefore, they were ideal soilless substrate and could substitute for tuff in production practice.
