Causes of and Preventive Measures for Dead Seedlings in Vegetable Peas Explained

Vegetable peas are a common field cash crop in our daily lives, with a relatively wide planting area, and in the process of pea cultivation, dead seedlings are a fairly common occurrence, often causing heavy losses to vegetable peas. So what causes dead seedlings in vegetable peas? How should they be prevented and controlled? Follow along with the editor to learn more.

I. Causes of Dead Seedlings in Vegetable Peas

There are many, chaotic and mixed pea seeds on the market, and many varieties that are highly susceptible to disease have flowed into the market without undergoing any testing, which is one of the important causes of dead seedlings in peas. Planting vegetable peas year-round in the same plot cannot break the infection cycle of pests and diseases, resulting in severe dead seedlings. After pea harvest, straw piled and scattered carelessly and not treated in time 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 with soil, causes the seeds to be exposed, and the seedlings are directly scorched to death by strong light. Artificially loosening the root system, as well as plants being blown by wind after reaching a certain height once trellised with strings, causes the root system to break and die.

II. Preventive Measures

In response to the causes of dead seedlings in peas, corresponding technical harvesting measures should be adopted for prevention and control. The editor has selected the following technical measures for preventing and controlling dead seedlings in vegetable peas, 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 vegetable 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 vegetable peas, and at the same time can greatly prevent the occurrence of dead seedlings. You can choose varieties that have been promoted locally or cultivated before with relatively high yields. Variety selection should be adapted to local conditions; not every high-yield variety can adapt to the local environment. Before large-scale sowing, trial planting can be carried out to see how 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.
