Green Bamboo Shoots (Horseshoe Shoots)
Green bamboo (Dendrocalamopsisoldhami) is a plant of the Poaceae subfamily of bamboos, mainly cultivated for the production of edible fresh bamboo shoots; because the bamboo shoots it produces are shaped like horseshoes, they are also called "horseshoe shoots". 3.2
The rooting part of the bamboo stalk. It consists of several to dozens of nodes, with short and thick internodes and large buds on them. 3.3
The lowest part of the bamboo stalk. Connected to the culm base of the mother bamboo, small, short, and rootless3.4
Shoot eyes (or bud eyes)
DB33/T3432015
A bud that grows at the culm base and sprouts into bamboo shoots. Shoot eyes are arranged alternately on both sides of the culm base. From the bottom to the top of the base, the first pair of shoot eyes that can sprout are called the head eyes, the second pair of shoot eyes are called the second eyes, and so on, the top pair of symmetrical tail eyes. Shoot eyes that cannot develop or die after sprouting are called virtual eyes. 3.5
Second water shoots
Shoots that sprout again in the same year after the early harvest of bamboo shoots. 3.6
Soil-drying eyes
A treatment method of digging up the topsoil before Qingming Festival to expose the bamboo shoots and shoots, and let all the shoots be exposed to the sun. 3.7
Bamboo shoot hole fertilization
A method of fertilization, in which fertilizer is applied into the hole after bamboo shoots are dug and covered with soil. The fertilization point is 10cm away from the cut shoots, and care should be taken not to splash fertilizer water on the shoots.

Size (kg/piece)
≥0.5~0.751 Time to harvest bamboo shoots
It is advisable to harvest bamboo shoots in the morning when the soil is cracked and moist, and before the bamboo shoots are about to emerge. 6.5.2 Methods of harvesting bamboo shoots
When harvesting bamboo shoots, first dig up the soil around the shoots to expose the shoots, and use a shoot chisel or a shoot-cutting knife to cut off the unemerged bamboo shoots from the inside to the outside along the upper part of the shoots, and keep 2 to 3 full shoots on the remaining shoots so that they can grow into bamboo shoots again. 6.5.3 Number of times to harvest bamboo shoots
In the early stage of bamboo shoot emergence (before July) and the late stage (after early September), bamboo shoots are harvested every 3 to 5 days, and all the bamboo shoots are harvested. In the peak period of bamboo shoot emergence (July to August), bamboo shoots are harvested every 1 to 3 days, and all the bamboo shoots except the mother bamboo are harvested. 6.6 Mother bamboo for fostering

It is advisable to select strong "two-water shoots" to keep mother bamboos, and at the same time, cut bamboo shoots with sprouting high buds such as tails. Avoid the new bamboo roots from forming a mound above the ground, so that the bamboo plants in the clump are evenly distributed and "scattered". 6.6.3 Number of bamboos to be kept
It is advisable to keep 5 to 7 mother bamboos in each clump.
6.7 Felling old bamboos
In winter or early spring, fell all 3-year-old old bamboos and some 2-year-old bamboos in the forest, and keep 2 to 3 2-year-old bamboos in each clump. To avoid winter cold damage, the removal of old bamboos can also be postponed to March in spring. 6.8 Weeding and loosening
Combined with cultivation measures such as digging up the soil, drying the bamboo shoots, and fertilizing, weeding should be carried out, and at the same time, the slender bamboo shoots sprouting from the old bamboo garden or the base of some bamboo shoots should be cleaned up: while cutting down the old bamboo, loosen the soil of the whole forest by 20cm. 7 Pest and disease control technology
