The latest course of cultivation techniques and methods of rich bamboos

Fugui bamboo, also known as sword leaf dragon blood tree, is a small evergreen tree, which can be used as potted plant or cut flower material. In recent years, the "tower" shape, also known as "Kaiyun bamboo", knitting shape and curved bamboo ornamental value, is very popular in the market.

Fugui bamboo likes shade, dampness and high temperature, shade resistance, waterlogging resistance, strong fertility resistance, and semi-shade environment. The suitable growth temperature is 20 ℃ and 28 ℃, which can withstand the low temperature of 2 Mel and 3 Mel, but it should be frost-proof in winter, and the best growth period is high temperature and humidity in summer. The cultivated land should be 1.8 meters high and the shading rate should be 75%. Avoid direct exposure to strong light, otherwise it will cause leaves to turn yellow and scorch, affect growth and reduce value.

Reproduction method

Rich bamboo stem nodes have strong root germination power, and cuttings are often used to raise seedlings, which can be carried out all year round in Yunfu.

Generally, the stem segments without leaves are cut as cuttings, which are 5 meters long and 10 centimeters long, and three nodes are inserted into the sand bed or semi-muddy sandy soil. The stems can sprout and sprout in 30 days, and they can be transplanted into the field or pot in 35 days. The terminal bud can also be cut into 10ml 15cm and inserted directly into the field or pot, and the most suitable cutting period is spring.

Field cultivation

The main purpose of field cultivation of Fugui bamboo is to collect erect tall stems as modeling and cut flower materials, and to cultivate erect sturdy stems as the main purpose.

1. Soil preparation: it is appropriate to choose deep and fertile sandy soil or semi-muddy sandy soil, applying 2500 MUR 3000 kg of rotten farm manure or 2000 kg of rotten livestock and poultry manure per mu, 250 Mel 300 kg of phosphate fertilizer, ploughing the soil twice, the width of the bed is 1.2 m, the height of the border is 20 mi 30 cm, the distance of the border is 40m 50 cm, and the irrigation and storage ditch is 40 mi 50 cm deep around.

2. Planting: a shallow trench is opened with a row spacing of 25 cm, and the plant spacing is about 15 cm. 1.4-17000 plants can be planted per mu.

3. Fertilizer and water management: 15 days after planting, 15 days after planting, nitrogen fertilizer can be applied thinly, urea 15 kg per mu and boiling water. Fertilizing every 15 days at seedling stage, urea 15kg / mu, potash fertilizer 15kg / mu, phosphate fertilizer 20kg / mu, nitrogen, phosphorus and potassium compound fertilizer 35ml / 40kg, or mature human feces and urine fertilizer 2000 kg / mu were applied to promote the growth of buds. Loosen the soil properly in the early stage and weed in time. Leave 3 thick and strong buds per plant, remove young and weak buds in time to prevent excessive density from affecting growth, the temperature warms up in April, apply 40 Mel 50 kg ternary compound fertilizer twice a month to promote stem and leaf elongation and stem sturdiness. Once heavy fertilizer was applied from May to June, 50kg of bran powder, 50kg of phosphate fertilizer or 600,800kg of rotten chicken manure were applied per mu, and then the land was properly cultivated to prevent plant lodging. In the future, depending on the growth of rich bamboo, topdressing is appropriate to avoid excessive growth of leaves caused by partial nitrogen. Spraying foliar fertilizer every 15 min 20 days and planting Bao Su can promote the stem to be tall and sturdy, the leaves dark green and the leaves thicker.

It is suitable for rich bamboo to be moist for a long time, and the border pit should be kept in shallow water, and the high temperature should be sprinkled to cool and moisturize, and water should be drenched every time to promote the dissolution of fertilizer to facilitate root absorption and make the plant grow exuberantly.

4. Plug rod and pull cable. When the plant grows to a certain height, it is easy to cause lodging due to the self-weight of the upper part, which affects the growth and causes the stem to bend. Insert the bamboo pole every 1.5 meters in the border and pull the line along the pole to prevent lodging. Pay attention to the typhoon attack, strengthen the shade shed, and do a good job of wind prevention.

Pot maintenance

The pot cultivation of rich and precious bamboo can be planted with rotten leaf soil, vegetable garden soil and river sand mixed soil, coconut bran and rotten leaf soil, cinder ash plus a small amount of chicken dung, bean cake and compound fertilizer, or high quality pond mud can be used as culture soil. There were 6 plants survived by cuttings or 12 plants with terminal buds in each pot. The growing season should always keep the basin soil moist, do not let the basin soil dry and white; in the middle of summer, we should often spray to cool down to avoid leaf tip and leaf drying; in winter, we should do a good job of preventing cold and freezing, so as to prevent leaves from yellowing and premature senescence. Nitrogen, phosphorus and potassium compound fertilizer was applied every 25 days and evenly applied around the flowerpot. Potted rich bamboo pots are changed every 1-2 years, old roots and old mud are removed, and new culture soil is added to promote the early development of new seedlings.

Pest control

Rich bamboo is often damaged by leaf mites, shell insects, ground tigers, earthworms, rice locusts and so on. To control anthracnose and leaf spot, topzine, Garinon, banana banana and anthrax Fumei were sprayed and used alternately. The medicine is used every 10 times every 15 days.
