A method for improving the yield and quality of morning glory seed production

Abstract

The invention discloses a method for improvinghybrid seedsyield and quality of morning glory. The method includes: 1) sowing the seedling; 2) applying sufficient base fertilizers to the hybrid seeds production field, deeply ploughing the field, preparing deep furrow and wide cultivation ridges, and then covering the periphery of survived plants with wet rice husk or substrates; 3)15-20 days afterplanting, performing pinching and topping processes on the fifth-sixth sections; 4) performing normal water and fertilizer management during the growth of the morning glory plants, removing leaf budsat the bottom of main branches, or removing all the buds below the pinching site of the main branches, and removing 3-4 newly born leaf buds in other parts of the plants at an interval of 7-10 days; 5) selecting flower budswhichare about to blossom, tearing off the top of the petals so as toenable the stamens to stretch out the outer side of the corolla; 6) harvesting the seeds of morning glory inbatches. The method effectively improves the yield of the seeds, solves the problems that the morning glory plants are prone to lodging and have poor seed-bearing performance in high temperature andhigh humidity environment in summer due to vigorous vegetative growth,greatly improves the yield and quality of the seeds, and increases the benefit.
