Balcony planting American shelf beans only bloom without pods, how to pollinate

1. Prepare in advance.

Brush white paper. Scissors.

Second, the method steps.

First, cut off the male flowers, place the flowers upside down on white paper or glassware, and tap the top part to make the pollen fall.

Prepare a small brush or use a small cotton swab (to prevent too much pollen from sticking at once). If the pollen is a little larger, it can be easily picked up by dipping it with some water.

Gently rub a cotton swab stained with pollen over the stigma of the flower. Allow the pollen to stick to the stigma. Note that this operation should not be repeated too many times, one is to avoid harming the flowers, but repeating it many times may wipe off the pollen that was originally stained, and the effect is not great.

So just be careful and do it a few times. (Some pollen is too fine to judge whether it was successfully pollinated, but as long as it is basically guaranteed to be roughly stained), it is fine).

Self-pollination, without manual effort, may be too high in temperature or not suitable for moisture.

The U.S. shelf bean, which cannot be cultivated in keep, is not a genetically modified product and may be a hybrid; Hybrid seeds, on the other hand, are not allowed to remain in the seed.

American shelfless beans.

American shelf bean is a bean variety introduced from the United States with an erect plant and a plant height of 50 to 60 cm.

Breed source. Introduced from the United States.

Main traits. The plant is erect, 50 to 60 cm tall, with strong branching, short internodes, thick peduncles, and infinite pod-setting habits. The pod is 40 55cm long, the pod is coarse, the tender pod is light green, the later stage is milky white, the meat is thick, the fiber is less, the aging resistance, the taste is good, the pod is sown in spring for 60 days, and the fresh pod can be marketed for 40 days in summer. The pod-setting period is more than 120 days, and the general fresh pod yield is 3000kg 667 square meters, and the harvest is 4000kg 667 square meters.

Suitable area. It is suitable for cultivation all over the country. It is suitable for interplanting with potatoes, melons and other crops, and the benefits are very considerable.

Key points of cultivation techniques.

Spring sowing from mid-March to late April, summer sowing or autumn sowing early June and late July, generally 3 July can be sown, row spacing 50cm, hole torch 30cm, each hole seedlings 2 3 plants, the amount of seed 2kg 667 square meters of American shelf cowpea plants are short, elastic, not lodging, strong wind resistance, do not need to build a frame, save labor and materials, for the lack of bamboo and wood pole in the area, it is worth promoting.
