Detailed Explanation of Key Points and Management Methods for Bamboo Shoot Cultivation
Bamboo shoots are the young sprouts of bamboo and are a prized delicacy in China, with a long history of consumption and cultivation. They are fragrant and crisp, and are deeply loved by consumers. They also have certain medicinal value, with effects of clearing heat and resolving phlegm, and tonifying qi and harmonizing the stomach. In addition, they are low in fat and high in fiber, which can promote gastrointestinal motility, aid digestion, and to a certain extent help prevent gastrointestinal cancer. Below, Qinnong Net brings you the cultivation techniques, let's take a look.
1. Site Selection and Land Preparation
Bamboo is relatively common in southern China, and it has extremely strong growth vigor. In spring, after a rain, small shoots sprout throughout the bamboo forest. Therefore, the soil chosen for planting must be loose and light in texture so that it can grow quickly. It grows best in fertile, loose, slightly acidic soil with deep soil layers, producing higher yields. It can also grow normally in relatively clayey soil, but the yield and quality are average. Land preparation is mainly done by digging pits, which facilitates management and planting. The general specification is 0.6m×0.6m×0.5m, then the topsoil is backfilled. When backfilling, an appropriate amount of organic fertilizer can be applied.
2. Seed Selection and Seedling Raising
There are also many varieties of bamboo shoots. In order to increase yield and maximize economic benefits, it is best to select narrow-leaf bamboo as the mother bamboo. Narrow-leaf bamboo is characterized by small and narrow leaves, flat nodes, earlier shooting, and a long shooting period. Its bamboo shoots are thick and crisp with extremely high yield. Select one- to two-year-old new bamboo as the bamboo rhizome; those over three years old are not suitable as mother bamboo, as their rhizomes have few buds, produce few shoots, and have a low transplant survival rate. Bury the rhizome with the culm for seedling raising. It is best to keep one or two live branches on the culm to improve the survival rate, then bury it in the soil. Generally, about 4000 rhizomes are buried per mu.
3. Reasonable Planting
After the bamboo seedlings are raised, they can be planted. Pay attention to the time and method when planting. The planting time is generally from February to March, when the temperature and climate are favorable for the growth of bamboo seedlings and the survival rate is relatively high. The root system of bamboo seedlings is highly lignified. If they are not planted in time after being lifted, they will lose water and the survival rate will be affected. Therefore, long-distance transport is generally not suitable for planting. The time from lifting to planting should not exceed 72 hours, and generally planting should be completed within 48 hours. When planting, the culm should be cut. When planting, the culm of the bamboo seedling should face downhill, forming an angle with the ground, and one to two live nodes and branches should be left outside the soil. This can reduce water evaporation and improve the survival rate. When planting, also pay attention to the planting density.
4. Later-Stage Management
To ensure yield, fertilizer and water management is essential during cultivation. The nutrients needed for bamboo growth must be guaranteed in order to harvest more high-quality bamboo shoots. Watering and fertilizing should be carried out each year according to the growth stages of the bamboo. Generally, topdressing is applied 3-4 times a year: the first time in May-June, the second time in August-September, the third time in November-December, and the fourth time in April of the following year. In the rainy season in southern China, drainage measures should be taken well to prevent excessive water accumulation in low-lying areas that can cause root rot. However, in high-temperature seasons, irrigation should be done in time to prevent the soil from being too dry and affecting yield.
