When should peas be planted? How to grow peas? Peas are a very tasty vegetable that can be added to a sauerkraut or meat to add more flavor. In recent years, the early winter vegetables planted in the southern part of Yongsheng County are mainly peas!
Pea planting technology points
1 variety selection
Choose Changshouren, a variety of adaptable and high-yield varieties.
2 Reasonable rotation
Rotation can be carried out with non-legume crop melons or grass crops.
3 Soil selection
Choose soil fertile, breathable, with a certain water source conditions, relatively concentrated high-quality flue-cured tobacco or corn.
4 seed treatment
Seeding for 1~2 days before sowing, increase seed germination rate and germination potential.
5 timely sowing
Sowing from mid-late September to early October is most suitable.
6 Reasonable close planting
According to the standard of flue-cured tobacco or corn noodles, sow 2 rows per soil, and use a small sputum to open the hole on both sides of the soot. The hole is 15cm, 3~5 grains per hole, 3~4cm of soil, used per acre. 6kg.
7 cultivating soil
Peas are prone to grass damage during seedling period. Weeding should be done early and in addition to small, do not injure the seedlings, and plant the soil of the pines to the roots before wintering. It is not advisable to weed the grass during the flowering and pod-forming period. Some large grasses in the field should be removed manually, and herbicides should not be used.
8 truss
When the stems of the seedlings grow to about 30cm, the first time they frame the vines. As the plant grows, the vines are pulled upwards every 40 cm upwards to ensure that the vines grow smoothly on the tobacco rods and plastic ropes.
9 Fertilizer management
Generally need to topdress 2 to 3 times. The application of nitrogen, phosphorus and potassium is combined, and the weak soil plot is combined with the irrigation water to apply urea 5kg. Generally, 10 kg of compound fertilizer is applied to the long-term cultivation of the vines, and 10 kg of compound fertilizer is applied in the pod-forming period, and the yield increase effect is obvious. In addition, after 2 to 3 times of harvesting, it can be properly topdressed according to the growth of the plant. The pod-forming period of the pea is generally more than 25d, and the pod is grown while growing. Therefore, in order to ensure the vegetative growth and reproductive growth, the harvest begins. When the back leaves are somewhat yellowed, they should be topdressed, and the compound fertilizer should be applied with 5kg of compound fertilizer, which can be applied by spraying or pouring water. Peas require high water content, both for drought and fear of phlegm, and the soil moisture should be kept at about 70%, especially during the flowering and pod-forming period. It should not be deficient in water, otherwise it will cause the flowers to fall into pods and affect the yield. In the case of drought, it is necessary to pay attention to the horse water or sprinkler irrigation from the ditch. In case of rain, it is necessary to timely drain the ditch, prevent moisture and stains, and ensure the drought and flood. In combination with pest control in the pod-forming stage, the foliar fertilizer can be sprayed 1~2 times to increase the pod formation rate.
10 pest control
During the growth and development of peas, the main pests and diseases are powdery mildew, downy mildew, leaf miner, bean pod, aphid and so on. Pests and diseases often cause peas to reduce production and cause planting failure. Therefore, pest control must be taken seriously, and the plant protection policy of “prevention first, comprehensive prevention†should be conscientiously implemented. Excellent varieties should be selected, with agricultural control as the focus, and biological control, physical control and chemical control should be adopted. The combined comprehensive control measures are strictly in accordance with the standards of pollution-free production, and the degree of damage caused by pests and diseases and the maximum residue of harmful substances are controlled within the scope of the state.
10.1 Agricultural control.
Implement farming methods such as tillage, crop rotation, and dumping, strengthen cultivating and weeding, and clean the countryside to reduce the number of pathogens and insect sources, and reduce the source of initial infection.
10.2 Biological (biological agents) Control.
Protect beneficial insects and promote the use of biological pesticides. For example, aphids and spotted flies can be controlled by biological pesticides or biological agents such as green waves, vegetables, and attractants.
10.3 Physical control.
It is recommended to use yellow boards to trap insects.
10.4 Chemical control.
Strengthen the prediction and forecast of pests and diseases in the field, master the dynamics of pests and diseases, timely control the pesticides, select high-efficiency, low-toxicity, low-residue pesticides, and use the selected agents in an alternating manner to reduce the resistance of pests and diseases. Strictly control the safety interval of pesticides, and strictly prohibit the use of high-toxic and high-residue pesticides.
11 timely harvest
Pea is a continuous flowering and continuous pod-forming crop. The pea harvesting standard is generally harvested 10 to 15 days after flowering. At this time, the pod is still dark green or begins to turn light green, the sugar in the bean is reduced, the starch is increased, and the flavor is increased. difference. Timely harvesting can reduce the supply of nutrients to the pods, promote the growth of upper stems and re-flowering pods, and increase yield. Picking pods is usually carried out in the morning. When harvesting, use both hands together. Cut the handle with one hand and pinch the pods with the other hand. Gently cut the pods, do not damage the plants, so as not to reduce the yield. The harvest period is up to 30. ~50d. One of the distinguishing features of peas is the timely harvesting of pods, the number of pods, and the high yield and efficiency.
The above is the pea planting technology provided by Hui Nong.com, and the interested farmers can refer to it. Pea is an ancient cultivated crop. Pea is rich in nutrients. The grain contains 20% to 34% of protein. The tender pod contains 16 kinds of amino acids required by the human body. It is a high-grade dish. In Yongsheng County of China, the main vegetables in winter and early days are mainly peas, because Yongsheng County is a typical South Asian hot monsoon climate zone, rich in light, heat and water resources. In the south of the dry-hot valley area, the towns of Chengna, Chenghai, Taoyuan, and Jiaojiao have an average elevation of 1,378m, an average annual temperature of 19.3°C, and sufficient sunshine to produce various vegetables throughout the year.
