红旱莲 Hypericum ascyron 在育苗移栽时,常采用数株丛栽法。由于种植密度过大易引起病害而影响产量。为探索红旱莲种植的适宜密度,提高大面积丰产栽培技术,特设本试验。1 试验方法 试验于1996年和1997年在南通农垦农科所内进行。1996年2月9日播种,5月下旬定植。试验设三个密度处理:每亩15000株、12000株和9600株,相应的株行距分别为15cm×30 cm、18 cm×30 cm、23 cm×30 cm。小区面积 0.013亩(4.8 m×1.8 m),重复三次。
Eclipta Hypericum ascyron in transplanting seedlings, often using several plant Cong planted. Due to planting density is too large to cause disease and affect the yield. In order to explore the appropriate density of Eclipta grown, improve large-area high-yield cultivation techniques, ad hoc this test. A test method Test in 1996 and 1997 in Nantong Agricultural Reclamation Institute within. February 9, 1996 planting, planting in late May. The experiment set three density treatment: 15000 per mu, 12000 and 9600 strains per acre, the corresponding strains were 15cm × 30cm, 18cm × 30cm, 23cm × 30cm. Residential area of 0.013 mu (4.8 m × 1.8 m), repeated three times.
