How to raise cactus culture method

Cactus can be dustproof, clean the environment, and easy to cultivate, so it is very popular with people. However, we also need to pay more attention when breeding, so that cactus can grow better, let's take a look at how cactus!

How to raise cactus

I. Environmental conditions

Most of the natural growth conditions of cactus are relatively poor, but in order to obtain high yield of cactus planting, attention should be paid to the requirements of temperature, moisture, light, ventilation, soil and other conditions.

1. Temperature requirements

It is a limiting factor for the natural distribution of cacti. Its growth requirements are 15-40℃, and the best range is 20-30℃. In the north, it can be cultivated in protected areas such as plastic film to ensure its healthy growth.

2. Requirements for moisture, light, ventilation and soil

Cactus drought, afraid of water, therefore, on the one hand, should pay attention to the soil porosity and good permeability, on the one hand, watering to water thoroughly (infiltration into the soil), and do not cause water. Opuntia to soil adaptability, chernozem, red loam, loess and so on can be planted.

II. Pot management

Cactus has been widely transplanted from wild to indoor cultivation, reflecting a trend among city dwellers to select potted flower varieties. Due to the limited area of buildings and the dry air, large or delicate potted flowers often grow poorly. Only some small, drought-resistant, simple management and high ornamental value varieties are most suitable. Cactus plants just meet these requirements.

Indoor potted cactus, to select small, flowery bulb type is appropriate, cultivation of this kind of plant can not be considered drought tolerance, and ignore its normal watering and fertilization. Indoor cultivation, can be used on the windowsill with lead wire and plastic film to create a high temperature, high humidity enclosed space, most cacti in such conditions not only grow fast and crystal clear color.

Potting soil, good drainage ventilation requirements, calcareous sand or sandy loam. Do not water the newly planted cacti first, spray several times a day, water a little after half a month, water normally after new roots grow out. Winter temperature is low, when the plant enters dormant state, want to control watering. With the increase of temperature after spring, plant dormancy is gradually released, watering can be gradually increased. Apply decomposed thin liquid fertilizer every 10 days to half a month, and do not fertilize in winter.

In general residential conditions, make full use of space, cultivate dozens of pots of various cacti, decorate a small "cacti garden" is not difficult. When the turn of spring and summer, window sill on all kinds of cactus open a variety of flowers, people after work, rest in such conditions, not only can eliminate fatigue, but also is a kind of enjoyment of natural beauty.

III. Conservation management

1. Fertilization

There are two ways to fertilize cacti, base fertilizer and topdressing. Base fertilizer is applied to the soil at the time of preparation. The topdressing is carried out in different times: one is seedling fertilizer, which is applied when the seed buds grow to about 6 cm; the other is post-harvest fertilizer, which is applied to promote the continued germination of cacti after harvest. Do not apply any fertilizer during dormancy.

2. Watering

Cactus just planted after not watering, wait for its root germination and then watering, watering each time to irrigate enough. It is not advisable to water more at ordinary times, and ponding in the planting ground should be avoided. Generally in the surface 15 cm below, hand pinch soil can not be a group to timely supplement water.

3. Weeding

Weeding should be done frequently to prevent weeds and plants from competing for water and fertilizer, and it can also play a role in loosening soil and ventilation.

4. Picking

(1) The best picking time of vegetable slice is when there is no obvious scar or disease spot within one month after germination, and the second or third thorn seat falls off. The older the stem, the more acidic it is; picking too early will affect yield and quality.

(2) Seed picking: As a seed, the growth period should reach more than 3-4 months, the stem thorns are all detached, the growth is full and robust, and there are no scars and disease spots. After harvesting, it is dried in the shade for 3-5 days. When the wound is slightly dry or soaked in Bordeaux mixture, the incision can be planted or sold.

5. Soil cultivation

In the process of cactus growth and development, with the increase of the weight of the above-ground part, soil should be cultivated in time to avoid lodging.
