Latest Management Techniques and Key Points for Peas During the Podding Stage

The peak growth period of pea planting is the podding stage of peas. At this time, sufficient fertilizer and water are needed, as well as measures such as pruning and training to regulate the growth of peas. So what measures are generally used to assist regulation, and how should fertilizer and water be managed? Please pay attention to the following content.

I. Pruning

1. Removing buds

The lateral buds at the base can be removed to improve ventilation and light penetration, increase photosynthesis, reduce crowding, lower humidity, and avoid diseases caused by the lower branches and tips touching the ground. It can also avoid unnecessary nutrient consumption, supply nutrients to the main branches, and then promote the main branches to thicken and set pods.

2. Pinching

Keep the main vine and a few lateral vines, then remove the excess parts, and remove the terminal buds on both the main vine and lateral vines. Eliminate apical dominance, conserve nutrients so the vines thicken, and avoid excessive vegetative growth, so as not to consume too many nutrients and reduce the quality of the retained pods.

II. Light

When growing peas in greenhouses, the duration of light exposure can be adjusted. Generally, peas are not very strict about light duration during podding, and they can grow well in open fields without adjustment. However, pea pods are afraid of strong light and need sunlight; strong light will cause peas to lose water, so shading can be provided in strong light weather.

III. Fertilizer and Water

Pea roots are not strong and need water, but waterlogging must be avoided. Generally, keep the soil alternately dry and moist, and apply more fertilizer and water during the podding stage. However, do not use flood irrigation, and do not apply too much fertilizer at one time; it can be applied multiple times during this period. Podding fertilizer is the main topdressing at this stage. After the young pods have set, apply fertilizer and water together, about 100 jin of compound fertilizer per mu, and water one week after application to promote dissolution and absorption. Water once a week and fertilize once every 1.5 months until podding stops, but topdressing can extend the growth period of peas.

IV. Pest and Disease Control

The main disease of peas is brown spot, which mainly damages leaves, stems, and pods, showing brown concentric rings and causing leaves to wither and die. It is generally induced by low temperatures. In the early stage of the disease, spray 70% thiophanate-methyl wettable powder at 500 times dilution, once a week, for several consecutive weeks. The main pest is the black leafminer, whose larvae mainly bore into the xylem inside the stems and mainly damage legumes. Spray 45% phoxim emulsifiable concentrate diluted 1000 times with water.

During the podding stage of peas, the main thing is to carry out the above work content, and these key points must be paid attention to. Through the above simple introduction, everyone should have learned some content. For more other content, please pay attention to subsequent updates.
