Golden medal is a kind of herbaceous plant with yellow flowers, red halo, easy to open, slender and spiny branches. The classification criteria are as follows: first grade, more than 40 cm, straight branches, full bracts, fresh leaves, no diseases and pests. Second grade, 30 ~ 40cm, straight branches, full bracts, fresh leaves, no diseases and pests. Third grade, below 30cm, the flower branches are curved, the flower buds are full, the leaves are slightly mottled, and there are no diseases and pests.

Breeding technology

Soil and fertilizer conditions

The cutting position should be well ventilated, sunny and with sufficient water flow. A well drained place. The base fertilizer should be prepared before cutting, and horse manure is a better choice. Pour the horse dung which has been heaped up to 50 ℃ to 60 ℃ into the hotbed, and then spray water with a thickness of 15-20 cm, about 1 kg of water per square meter. When stepping on the hotbed, it should be damp. But not to Wang Shui. Spread the fully heated horse dung on the upper ten layers. Spread the relatively raw horse dung on the lower layer, so as to keep the heat lasting for a long time and balance the heat. The top layer is paved with coarse sand 15 cm thick (sand diameter 1-1.5 mm). If the sand is mixed with soil and humus, it must be washed clean and then laid into the bed. Cover the window sash of the hotbed after spreading the fecal sand. After a day in the sun, cover it with straw curtain at night to make the temperature in the bed rise. The next day, the cutting will be done.

slotting machine

Slotting bed is generally 10 meters long and 1 meter wide. The bed surface is paved with pure sand about 10 cm, and the bed is equipped with a film cover, which is about 0.5 meters high. The size of the bed and the framework of the cover can be adapted to local conditions, with local materials and antirust and anticorrosive materials.

Shade shed

There is no shade shed at the height of about 1-2 meters from the cutting bed. When erecting the shade shed, the distance between the shed top and the film cover should be more than 40 cm, so as to ventilate and cool down, and facilitate the hanging of the shade shed around, so as to prevent the oblique sunlight.

cuttage

Based on the field experience and personal practice, the internal and external factors affecting the survival of winter cuttings were found out, mainly including temperature, humidity, sunlight intensity and the quality of cuttings.

Cutting period

In recent years, we summarized the experience and found out the reasons why the transplanting was not viable or the survival rate was very low. The first link is the cutting period, so in late May to mid June, only more than 20 days is the best period. The spring of that year is used as a stick. At this time, the spring of that year is in a semi mature state. It has abundant nourishment, vigorous physiological function and strong rooting power.

Cutting medium

Sand and silica as the best, sand matrix, because of the sand gap, good ventilation, easy to disinfect, free from disease and insect damage, good for cuttings rooting, low material cost. Spread about 10 cm coarse sand on the open cutting bed, use the ballast light town, in the pouring water, you can cut.

Cutting cutting

The following points should be paid attention to in cutting: take the tender branches of the current year, do not highlight the branches and flowering branches, the branches should be strong branches with insect pests, short nodes, strong and complete leaves; the maturity of the branches should be semi lignified, i.e. 50% - 70% lignification; the tender part of the old is not easy to live: the length of the cuttings should be 8-10 cm, and at least three nodes should be reserved; the upper end of the cuttings should be selected Reserved leaves: the second blade at the upper end of the cuttings must be well developed, because the reserved leaflets continue to produce nutrients. For cuttings rooting, germination needs. In order to reduce the water loss phenomenon of transpiration, 1 / 2 of each leaflet is subtracted. The lower leaf umbrella is removed: the upper and lower cut of cuttings: the upper cut is 0.5cm above the upper bud. If it is too short, the withered tip will affect the preservation of the mother leaf. The lower cut is near the end of the lower bud, and oblique cut, because this part has sufficient nutrients to benefit the root: prevent the water loss of cuttings and shorten the collection time as much as possible Between. It's best to do it in the warm and windless morning or evening, picking and processing under shady and cool trees, plus good plug and play, and the smell is too long when not put (not put into water).

Cutting depth and density

The cutting depth is about 2-3cm, so it should be shallow and can stand. Because of the high surface temperature, it is favorable for rooting, and the density is 6 × 6cm. It is suitable that the leaves do not touch each other. To facilitate light and air circulation. Easy to root.

Management before survival

After the insertion, the water is permeable and then covered with shrinkage film. In the process of cutting survival management, we must not only improve the air humidity to prevent the upper leaves of branches from wilting and drooping, but also control the high humidity of cutting substrate to avoid the lower part of cuttings from anoxia, suffocation and mildew. Therefore, after the first watering after cutting, the weather and water holding capacity of cutting substrate should be tested. If the weather is hot, it can be watered 2-3 times a day with fine eye watering pot, and the amount of watering can keep the substrate moist and quickly swept. If the humidity of the substrate is suitable, the spout can be used to spray the leaves, so that the leaves are fresh green and erect, without wilting and sagging. If the temperature in the shed exceeds 30 ℃, it is hot at noon, and the water can be sprayed outside the shed to cool down. The ventilation should be carried out along with the watering, and no large amount of ventilation is needed. The best temperature for cutting survival is 22 ℃ - 32 ℃, and the relative humidity of air is more than 90%.

Rooting time and growth

When the temperature and humidity were suitable, the callus appeared 6-8 days after poke, and adventitious roots were born about 13 days after poke. The small roots formed in the callus, mostly in the tip of the cutting shoe, 2-3 in a few days, about 1 cm long. At this time, new shoots appeared. About one month (in the middle of July) the new shoots were pulled out about 10 cm and the roots were collected 4-5 roots. In two months, the root length is more than 26 cm, and the new shoot length is more than 20 cm.

Ventilation and light

It's better to remove the film cover and roll up the reed curtain sooner or later. The weather is hot and dry. You can use a small eye watering can to water 2-3 times a day and spray the leaves. You must not water more. In order to find the source of water, gradually strengthen the light and reduce the frequency of water supply, and exercise to adapt to the external conditions.

Upper basin transplantation

After the survival of the seedlings, about 30 days later can be on the basin, out of the cutting seedbed. The first transplantation was root transplantation. Therefore, careful management must be carried out during operation. Small flowerpots should be planted with fully decomposed humus soil and plant ash, or with fertile garden soil. They should be planted as soon as the seedlings are raised and irrigated immediately after planting. Then it must still be covered in a hotbed. Proper management (management is the same as the initial insertion). After 3-5 days, the windward time was gradually extended to make the growth environment similar to the open field, and then the soil ball was moved into the open field seedbed. Transplanting should be carried out later, that is to say, the young roots should change from white to yellowish brown to black, that is, after the root system reaches the degree of quality, the open root transplanting should be carried out in the open seedbed. The transplanting should be carried out at night, and should be properly shaded for one or two days.

Pest control

In this period, powdery mildew is easy to occur. If the disease occurs, the ventilation time should be appropriately increased, and yituyute powder should be used in time. The pests are aphids. Use 1/1000's dimethoate spray to remove it.

Flower language:

For friendship, yellow rose represents pure friendship and good wishes, so it would be a good gift to give to a good friend.

For love, yellow rose represents passion, true love and apology for love. Heavy blessing, infidelity, jealousy, lovelorn, apology. But in some places, yellow rose also represents waiting, waiting for your love.

Flower language of Yellow Rose: the love of good fortune

Rose has been playing an important role in the field of horticulture since ancient times. In other words, yellow rose can be regarded as the leader of flowers. So its flower language is - luck.
