Abstract:

Three farm chemicals were chosen and compounded, i.e. Liangdun (seed coating agent for preventing root rot), Gaoqiao (insect repellent for indirectly preventing virus disease) and Kaipuke (promoting plant growth) to screen out the suitable compound seed coating for pea seeds. The seeds of four vegetable pea cultivars, Tianwan 3, Lübao, Baofeng 6 and Shijiadacaiwan 1, were coated with the compound seed coating agents. The suitable ratio of agent and seed would be selected on the basis of performance of seedling rate, important agronomic characters and yield. The results were as follows: when the ratio of agent and seed was 1:0.5, the seedling emergence rates of Tianwan 3 and Lübao were restrained; when the ratio was 1:7.5, there was no significant difference in seedling emergence rate, farm characters and yield compared with the control group; when the ratio was 1:5.0, the seedling emergence rate was the highest with the best seedling quality; the average yield was 20.5% higher than that of the control group. Therefore, the best proportion of coating pea seeds with the compound seed coating agent is the formulation of the mixture of Liangdun 10mL, Gaoqiao 20mL and Kaipuke 10mL for pea seeds 5.0kg.

Key words: Pea (Pisum sativum L.), Compound seed coat agent, Growth, Yield
