Cutting of huci plum: three steps to teach you to complete cutting

Nitraria roxburghii is a kind of common ornamental plants. Because it is easy to take care of, very ornamental, so it has become a favorite of home plants. Some flower friends tell Xiaobian that it has no seeds, how to breed? Cutting is the main way of propagation. What are the specific steps? Let's look down~

Cutting matrix: it is used for cutting nutrient soil or river sand, mud carbon soil and other materials. It is very difficult to get the ideal cutting substrate for family cuttings. It is recommended to use the cuttings that have been prepared and detoxified; medium coarse river sand can also be used, but it should be washed with water several times before use. Sea sand and river sand in saline alkali areas should not be used because they are not suitable for the growth of flowers and plants.

2. Cutting time and temperature: in early spring or late autumn (the highest temperature at noon is no more than 28 ℃, and the lowest at night is no less than 15 ℃), the leaves or stems (with 3-4 leaf nodes) are cut. After the wounds are dried, they are inserted into the matrix, and the cuttings and matrix are slightly wetted. As long as the substrate is not excessively dry or water stained, roots and new shoots can be quickly grown.

3, the selection of cuttings and cutting process: first, combined with spring pruning, select the last year's mature and strong branches from the mother plant and cut them into 10 cm to 12 cm section. As the cut has white emulsion outflow, after the cuttings are cut, rinse immediately with water or cut the leaves into the grass and ash, and slightly dry them. When the branches are slightly soft, they are inserted in the sand bed according to row spacing 5 cm *5 cm. In plain sand soil or mixed with fine sand and rice husk ash, or in loam with good drainage, the depth of cuttings into the soil is about 4 cm to 5 cm.

Cutting management: 1. Humidity Management: like dry air environment, rainy days last too long, easy to be infected by pathogens. Keep the leaves dry at night. The optimum air relative humidity is 40-60%.

2. Temperature management: the most suitable growth temperature is 15 ℃ ~ 32 ℃. It is afraid of high temperature and sultry. It will enter into dormancy state when the temperature is above 33 ℃ in summer. Avoid cold and frost. The winter temperature needs to be kept above 10 ℃. If the temperature drops below 4 ℃ in winter, it will also enter into dormancy state. If the ambient temperature is close to 0 ℃, it will die due to frostbite.

In summer:

(1) Strengthen the air convection, so that the temperature in the body can be emitted;

(2) Put it in half shade or give it 50% shade;

(3) spray it properly, 2~3 times a day.

In winter:

(1) Move to a bright indoor place for maintenance;

(2) In the outdoor, the film can be wrapped up for the winter, but every two days, the film should be opened when the temperature is high at noon to let it breathe;

3. Light management: in summer, the leaves will be more beautiful if they are kept in half shade or 50% shade. In spring and autumn, because the temperature is not very high, it should be given direct sunlight to facilitate its photosynthesis and accumulation of nutrients. In winter, it should be kept indoors where there is bright light. For indoor maintenance, they should be placed near doors and windows facing Southeast to receive light. After one month or one and a half months, they should be moved outdoors for maintenance for two months. Otherwise, the leaves will grow thin and yellow, and the new branches or petioles will be thin and yellow, and the internodes will be elongated.

4. Fertilizer and water management: it has strong drought tolerance and can grow in arid environment, but this does not mean that it is not watered or fertilized; its root system is afraid of water logging, if the flowerpot is filled with water, or if it is watered and fertilized too frequently, it will easily cause rotten roots. The principle of fertilizing and watering it is "between dry and wet, dry to thoroughly dry, not dry do not water, water thoroughly", when watering fertilizer, avoid wetting the plant in the daytime.

(1) Spring and Autumn: these two seasons are the peak seasons for its growth. The management of fertilizer and water is in the order of "Huabao" - Qingshui - "Huabao" - clear water. The interval period is about 2-4 days for outdoor maintenance, 3-6 days for indoor maintenance, shorter intervals for sunny days or high temperature periods, longer intervals or no watering for rainy days or low temperature periods.

(2) Summer: during the high temperature period in summer, it often goes into dormancy state, and there is not much demand for fertilizer and water. Even the fertilizer and water should be controlled. The interval period is about 3-5 days for outdoor maintenance and 4-7 days for indoor maintenance. Watering time should be arranged in the morning or evening when the temperature is low. Spray the plants regularly.

(3) Winter: in the winter dormancy period, the main task is to control fertilizer and water. Fertilizer and water management is in the order of "Huabao" - Qingshui - "Huabao" - Qingshui - Qingshui, with an interval of about 7-10 days. Watering time should be arranged in sunny days at noon when the temperature is higher.

5. Conservation and pest

(1) The leaf clump grows upright and upward, and the flowerpot is better with a deeper tube, which is more compact and beautiful. The pot soil can be composted with two parts of garden soil and river sand respectively, and a small amount of horseshoe bone meal can be used as base fertilizer. The pot can be changed once a year or two. In spring and autumn and winter, it can be maintained in a place with good light conditions, water every 2-3 days, keep the basin soil slightly wet, and apply fertilizer every half a month. In winter, water and fertilizer should be controlled to prevent root system and leaf base from rotting.

(2) 50% carbosulfan 800 times solution was sprayed once every half a month. The insect pests were whitefly and scale insect, which were sprayed with 1500 times of 50% fenitrazole EC.
