在网棚内,采用基质栽培模式,研究了猪粪、沙子组合基质与微型薯生长发育和经济效益间的关系。结果表明:各因素对微型薯单粒重、单株粒重、繁殖效率的效应(R)是猪粪>蛭石>沙子;因素间最佳容积比是:A2B3C3,即沙子、猪粪、蛭石容积比分别为0.40:0.40:0.20。微型薯存活率、基本苗变化顺序是:传统蛭石(CK)>组合基质;而生物学性状、经济性状、经济效益变化顺序是:组合基质>传统蛭石(CK)。组合基质与传统蛭石(CK)比较,微型薯株高、茎粗、地上部分干重分别增加35.68 cm、0.14 cm和2.47 g/株;单株粒重、单粒重、单株粒数、繁殖效率分别增加了0.88 g/株、0.15 g、0.18粒和30.14粒/m2;产值、利润分别增加了10.55元/m2和16.15元/m2;基质成本降低了5.60元/m2。
In the net shed, the substrate cultivation mode was used to study the relationship between pig manure and sand matrix and the growth and economic benefits of microtubers. The results showed that: the effect of each factor on single grain weight, grain weight per plant and reproductive efficiency (R) was pig manure> vermiculite> sand; the best volume ratio among the factors was A2B3C3, namely sand, pig manure, Stone volume ratio was 0.40: 0.40: 0.20. The order of the survival rate of micro-potatoes and the change of basic seedlings was: traditional vermiculite (CK)> composite substrate; and the order of biological traits, economic traits and economic benefits was: combination substrate> traditional vermiculite (CK). Compared with the traditional vermiculite (CK), the height, stem diameter and shoot dry weight of the miniature potato increased by 35.68 cm, 0.14 cm and 2.47 g / plant respectively. The grain weight per plant, single grain weight, The reproductive efficiency increased by 0.88 g / plant, 0.15 g, 0.18 plant and 30.14 plant / m2 respectively; the output value and profit increased by 10.55 yuan / m2 and 16.15 yuan / m2 respectively; and the cost of substrate was reduced by 5.60 yuan / m2.
