One, distinguish between large and small year: the moso bamboo has a law, every other year bamboo shoots more, in the middle of a clear break in the year, commonly known as large and small year. The big year of the moso bamboo in addition to the old bamboo, bamboo shade dense, dark green leaves, from a distance like a chicken feather duster. And the small year of even the bamboo strong years of the bamboo is also sparse like a shedding chicken. Some of the bamboo forest land barren or digging bamboo shoots too much, resulting in large and small years mixed serious, is the so-called "Peach Blossom Fanfan" "flower Actor Hill".

Two, recognize pregnant bamboo: farmers say: "open branch low and thick, double open bamboo shoots," meaning that the lowest branch for the double branch, open very low and very thick, its bamboo leaf piece long, thin, pointed and slightly with a few golden yellow leaves and the whole plant green for pregnant bamboo, because the bamboo shoots consume a certain amount of nutrients, the bottom leaf nutrition is transferred away, resulting in the leaf piece of the bamboo, the bamboo, the bamboo, the bamboo, the bamboo, the bamboo, the bamboo, the bamboo, the bamboo, the bamboo, the bamboo, the bamboo, the bamboo and the bamboo. Because the bamboo shoots consume some nutrients, the nutrients of the bottom leaves are transferred away, resulting in the yellowing of the leaves. The main whip of the pregnant bamboo is golden yellow in color, with a strong spirit, and the side buds are enlarged to produce more shoots, and the size of the shoots is also large.

Three, looking for the main whip: find the pregnant bamboo is not the same as finding the bamboo shoots, but also to find the main whip of the pregnant bamboo, how to find the main whip here to introduce the three commonly used methods:

1, the pregnant bamboo around the soil is dug up all the time, to find the thickest and the most powerful is that this method is the most stupid, the most tired, and also the most effective.

2, according to the direction of the lowest branch of the pregnant bamboo is roughly the same as the direction of the main whip, in the soil is relatively soft, the land undulation is relatively small flat, and its whip is relatively straight, the direction of the main whip is generally the same as the direction of the lowest branch.

3, according to the direction of the pregnant bamboo ports to determine the direction of the bend, the general bamboo out of the bamboo ports near there will be a curvature, because the shoots first outward growth, and then upward to about 45 degrees outward growth, and finally straight upward growth, to become a moso bamboo, the curvature of the plane formed by the vertical direction of the main whip and the direction of the main whip is roughly the same, but of course there is a certain degree of error, the bamboo shoots and the main whip was 90 degrees to 180 degrees are available.
