Effect of Field Management Techniques on the Yield of Paris polyphylla var.chinensis
In order to find out the influencing factors of the planting yield of Paris polyphylla var.chinensis,the L9(33)orthogonal experiment was used to design the three factors of different shading degree(a),fertilizer(b)and planting depth(c),each factor 3 level contrast test.The measured yield of 3-year-old Paris polyphylla var.chinen-sis seedlings after 4-year planting was used for statistical analysis.The results showed that:A＞C＞B,shading rate(a)was the main factor;fertilizer B and cover thickness C were the minor factors.The best results were ob-tained with shading rate a 2(60％),fertilizer b 1(farm manure+chemical fertilizer)and planting depth c 2(5～6 cm).A2、B1、C2 is the optimal treatment combination for the field planting management of Paris polyphylla.
