How to raise reticulate grass? Can the breeding methods and matters needing attention of reticulate grass be raised in water?

Fertilizer application: when applying fertilizer, the net grass also follows the fertilization principle of "light fertilizer applied frequently, less and more times, and complete nutrition". You can top fertilize compound fertilizer once a month.

Watering points: the watering time of reticulate grass should be arranged when the temperature is low in the morning as far as possible. Summer is watered in the morning or evening when the temperature is low, and plants are often sprayed. Winter: the watering time during the winter dormancy period is arranged as far as possible when the temperature is high at noon on a sunny day.

Key points of reproduction: when reticulate grass is propagated, cuttings can be cut from the stolon growing out of the basin, about 10 cm long, generally leaving 3 or 4 stem nodes, remove the lower leaves, dry slightly and insert into the sand bed. If the soil temperature is kept between 24-30 ℃, it can take root at 7-14 days after planting, and it can be transplanted into the pot after 1 month.

Pot soil replacement: reticulate grass in the cutting seedlings on the pot, should be careful not to damage the roots, and should be separated from fertilizer, avoid burning roots, watering after planting, and then can be transferred to normal maintenance.

Pest control:

The main results are as follows: 1. The common diseases of reticulate grass are leaf rot and root rot. Leaf rot was controlled by spraying 1000 times of carbendazim wettable powder. Root rot disease was sterilized by soaking the root with 1000 times solution of streptomycin.

2. The insect pests of reticulate grass include shell insects, red spiders and snails. Shell insects and red spiders were sprayed with 1000 times of omethoate EC. Snails can be caught manually or trapped by snails.

Basin soil requirements:

Potted soil is suitable for sandy loam rich in humus, and can also be prepared with peat soil or coconut 50%, pond mud 30%, river sand 20%, or loose and water-retaining grass carbon nutrient soil. Because its root system is shallow, it is better to use a large mouth and shallow basin instead of a high and deep basin for planting.

Temperature conditions:

The most suitable growth temperature of Rabdosia paniculata is 18 ℃-30 ℃. Avoid cold frost. The overwintering temperature should be kept above 10 ℃ in cold winter, and it will go into dormancy when the winter temperature drops below 4 ℃. If the ambient temperature is close to 0 ℃, it will die of frostbite.

Lighting conditions:

White reticulate grass avoid hot summer sun exposure, but need to grow in the appropriate sun exposure. Therefore, there should be 6 hours of scattered light at 4m / h every day. If the indoor light is insufficient, the pot plant can be placed under the fluorescent lamp at night to increase the light hours to ensure the plant's demand for weak light.

Watering method:

Watering should grasp the principle of "better wet than dry", but never accumulate water. Usually should keep the soil moist, winter cold current attack should pay attention to heat preservation and windbreak, reduce the amount of water. Watering in the morning is better to avoid the retention of water in the leaves at night, resulting in cold injury and decay.

Fertilization method:

It can grow well without fertilization. Granular compound fertilizer or rarefied liquid fertilizer can be applied every 1-2 months, which can brighten the color and luster of leaves. Attention should be paid to avoid fertilizer contact with leaves. In order to maintain the beautiful shape of the plant, the newly planted potted seedlings should be heart-picked many times to promote multi-branching.

Diseases and insect pests

Patellar diseases and insect pests often occur in the growth process of reticulate grass, but there are also diseases such as leaf rot and root rot, as well as shell insects, snails and red spiders.

Pick the heart

In the growing period of reticulate grass, in order to promote its multi-branching and control the height of the plant, it is necessary to pick the heart frequently, which is conducive to the vigorous growth of reticulated grass.

  in theory, the vast majority of plants can be hydroponic, but hydroponics has some disadvantages, such as short-term growth is good, long-term effect is not as good as soil cultivation, in addition, it also involves some domestication process, which seems simple, but in fact there are many ways to do things.

   said no more, we continue to talk about reticulate grass hydroponics, flower friends asked reticulate grass can hydroponic culture? The answer is yes, let's take a look at the specific steps.

The steps of hydroponic culture of reticulate grass grown in    soil:

   1. Prepare a water culture frame (mainly used to fix reticulate grass to prevent falling into the water to keep the roots from touching the water, but the leaves do not touch the water).

   2. Remove the reticulate grass from the soil, try not to hurt too many roots, and wash the soil clean.

   3. Put the network grass on the hydroponic frame, let the root system 2can3 into the water, and let the other one breathe in the air, and then put it in a place where there is no direct sunlight to maintain.
