What to Do About Dead Pea Seedlings? Causes and Prevention Measures Explained

Peas are a common field cash crop in our daily lives and are grown over a fairly wide area. During pea cultivation, dead seedlings are a rather common problem that often causes heavy losses. So what causes dead pea seedlings? How should they be prevented and controlled? Let's find out together.

I. Causes of Dead Pea Seedlings

Pea seeds on the market are numerous, chaotic and mixed, and many varieties that are highly susceptible to disease flow into the market without undergoing any testing, which is one of the important causes of dead pea seedlings. Growing peas in the same plot year after year makes it impossible to break the infection cycle of pests and diseases, resulting in severe dead seedlings. After harvesting peas, leaving the straw piled up and scattered around without timely disposal can also cause dead seedlings the following year. In addition, sowing too shallowly, or watering and fertilizing washing away the covering soil without timely re-covering, exposes the seeds, and the seedlings are directly scorched to death by strong light. Artificial loosening of the root system, and after the trellis and strings are set up, plants growing to a certain height being shaken by wind, cause the roots to break and the plants to die.

II. Prevention Measures

In response to the causes of dead pea seedlings, corresponding technical measures should be adopted for prevention and control. The editor has selected the following technical measures for preventing and controlling dead pea seedlings, for reference in large-scale production.

1. Field Plot Selection

Choose a field plot that has not grown peas for 3-4 years for planting, as this can greatly reduce pest and disease infection. Choose slightly acidic or neutral soil with a low groundwater table, convenient drainage and irrigation, and high organic matter content, to create a good environment for the growth and development of peas, cultivate strong seedlings, and reduce dead seedlings.

3. Selection of Good Varieties

Choosing excellent varieties with strong disease resistance is the key to high yields of peas, and at the same time can greatly prevent the occurrence of dead seedlings. You can choose locally promoted varieties or those that have been cultivated with relatively high yields. Variety selection should be adapted to local conditions; not every high-yielding variety can adapt to the local environment. Before large-scale sowing, trial planting can be carried out to see how well the seedlings adapt.

4. Seed Treatment

Before sowing, the seeds can be sun-dried for 2-3 days, which can significantly improve the germination rate and germination vigor of the seeds. In addition, promptly remove diseased grains, broken grains, shriveled grains and mixed grains to reduce the possibility of pest and disease infection and improve the uniformity and purity of the seeds.
