How to thin and set the final stand of directly sown rapeseed
Methods for thinning and setting the final stand of directly sown rapeseed ⟦3 (Agricultural Wealth Network) Directly sown rapeseed is sown at a high rate and a relatively high density. If it is not thinned and set to its final stand in time, the excessive density will cause the seedlings to crowd each other and produce thin, weak, spindly seedlings. Timely thinning and setting the final stand at the right time are very important. Generally, one thinning should be done right after the seedlings emerge, and a second thinning at the 2-leaf stage. The final stand is best set in time after 4 true leaves. At the same time, inspecting the seedlings and filling in gaps should be done promptly.
