Cultivator
Peas are prone to grass shortage during the seedling period and must be cultivated and weeded 2 or 3 times. The first cultivator is usually conducted when the plant height is 5 to 7 cm, and the second cultivator is performed when the plant height is 10 to 15 cm, and the soil is used in combination. The third cultivator should be based on the growth of peas. In the late period, the stems and leaves are luxuriant, and the cultivators tend to damage the plants, and the weeds must be removed manually for a long time.
2. Take a trip
The creeping peas must be erected when the plant height is about 30 centimeters. Otherwise, the vines on the vines will not only be inconvenient for field management and harvesting, but also the lower stems and leaves will be easily rotted and cause diseases. After racking, it was well ventilated and light-transmissive. The vines were stout, the basal rot was reduced, and the pods were full. The granules were full and the yield could be increased by more than 1 time. Some varieties need to be picked up at a height of 30 cm to promote the emergence of branches and increase the number of flowers and fruiting rate. The tender tips removed are also available for vegetable consumption.
3. Fertilization
Fertilizer peas should be based on basal fertilizer. In addition to applying compost and manure, more phosphorus and potassium fertilizers, such as grass ash and bone meal, should be applied. If you can use Rhizobium seed dressing when sowing, the effect is better. Rhizobium leguminosa can fix nitrogen, so it is not necessary to apply more nitrogen fertilizer; however, in the seedling stage and in the absence of soil fertility and lack of base fertilizer, a small amount of available nitrogen fertilizer can be applied to promote multiple stems and leaves. Peas need to use more phosphorus and potassium fertilizers. Phosphate fertilizer can promote the ripening of pea seeds, and can also improve its softness. Peas have a high utilization rate of insoluble phosphate fertilizer, and have a significant effect of increasing production after application; superphosphate can also be applied. Pea was sprayed with phosphate fertilizers outside the roots during flowering and podging, especially spraying boron, manganese, molybdenum and other trace element fertilizers. The effect of increasing yield was very significant.
4. Irrigation
Peas are poor in drought tolerance and should be irrigated during growth to keep the soil moist. If drought occurs after sowing, it must be quickly watered to facilitate seed germination and emergence. More water is needed during flowering and poding.
