The varieties of beans and vegetables in greenhouses can be selected as follows:
Oil bean
In recent years, the price of oil beans has not been low, and the recognized oil bean variety is a general.
The general red peas belong to the mid-early maturity vine variety, strong in growth; purple flowers, green pods, average pod length 20 cm, pod width 2.4 cm; no fiber, fleshy surface, excellent commercial, average 1600 kg per mu. The variety has strong disease resistance, strong resistance, wide adaptability, no premature aging, storage and transportation, and can be planted in spring and autumn. It can be cultivated in open fields and protected areas.
Bean
Planting beans, it is recommended to choose the Thai bean king. The variety has stable performance, high yield, disease resistance, no gluten and no fiber; pod green round stick shape, thick pod, pod length 30 cm or more, good commercial property; strong plant growth, more side branches, from sowing to harvesting The tender pod takes about 75 days, and the yield per mu is 3000-4000 kg. It is suitable for winter and spring protection and autumn open field cultivation. The planting row spacing should be 30-50 cm, and 1 to 2 seeds per hole.
Kidney bean
The cowpea varieties that are currently grown can be divided into white kidney beans and green kidney beans.
Among the white kidney bean varieties, nine white is the largest variety of planting area. The characteristics of nine white kidney beans are that there are 2 to 3 true leaves to flower and pod, which can be pods 20 days earlier than other varieties; 60 to 63 days from sowing to harvesting tender pods, harvesting period of more than half a year; pod length 26 ~ 30 cm, pods are light green and white, generally 5,000 kg of fresh pods per mu; wide adaptability, strong cold resistance, disease resistance and heat resistance, can be cultivated in open field, but also in protected areas.
The other type is green kidney beans, which are green or light green. Jiuqingqing is an early-maturing variety of green kidney beans. It takes about 45 days from sowing to harvesting. The plants grow vigorously, grow vigorously, and have strong branching power. The main vines and side branches are pods, and the continuous pod-forming rate is extremely high; pods are green and pods. It is 25 to 28 centimeters long and has a round and round shape. It has good commercial properties and cultivates more than 6,000 kilograms per mu. It has high temperature resistance and high resistance to anthracnose, rust and disease.
The planting area of ​​the wide-flat type cowpea in the green kidney bean is also very large, and the varieties with better performances include the double crown and the Dutch green sword. The double-crowned variety has a pod length of about 40 cm and a width of 3 to 4 cm. It has many pods, low temperature resistance, fast growth rate, no knots, and strong reproductive growth. It is suitable for planting in greenhouses and arch sheds in northern areas.
Kidney Beans (Long Beans)

The largest planting area is the yellow-grained green kidney beans. It is recommended that the vegetable farmers choose the Changlong No.5 variety. The variety is medium-ripe, the plants are sprawling, and the growth is strong. The main vines are mainly pods, with few branches, from sowing to harvesting. Around day, the pods are 70-85 cm long, up to 1 m long, and the yield per mu is as high as 4,000 kg. Red Beans are recommended to choose Gaoyou No.4. The variety is precocious, vine-grown, strong in growth, concentrated in pods, pods are long round, pods are 57-61 cm long, resistant to blight, heat and cold resistant, field It is more resistant to rust.
White and black peas are currently partially planted in the country and have not yet formed a large area.
Planting precautions
From the current point of view, there are not many varieties of legumes suitable for planting in greenhouses and arch sheds in the northern regions, and the yield of legumes is often not high, which is closely related to their planting management techniques. For example, legumes tend to grow in the early stage, and once they are prosperous, they are not conducive to flower bud differentiation, which will have a greater impact on their yield. Beans, cowpeas, and oil beans tend to be stronger, and cowpeas tend to be weaker. Therefore, cowpeas and oil beans should be specially planted to prevent premature growth. Compared with oil beans and cowpeas, cowpea has a weak ability to resist heavy weight, so cowpea should not be planted repeatedly so as not to affect its yield.
How to identify seed new
It is necessary to look at and listen to the identification of legume seeds. Look at the seed epidermis, umbilical cord and cotyledon, the new seed epidermis is bright, the umbilical white, the cotyledons are yellowish white, the cotyledons are closely connected with the seed coat; the epidermis of the Chen seed is dark and dull, the umbilical color is dark, the cotyledons are dark yellow or khaki, and Easy to peel off with the seed coat. Listening is the sound of the seed. When the new seed falls from a height, the sound is crisp and crisp; when the Chen seeds land from a height, the sound is empty. The bean seeds can also be shaken in the hand, listen to the crispness of the sound, identify the water content and germination rate, the sound is brittle and the water content is low, mostly the Chen seeds that lose the germination rate, the sound is cloudy and not crisp. Good rate, available.
