Cutting and pressing seedlings of Flos Lonicerae

I. Cuttage seedling

The cutting seedlings of Flos Lonicerae can be raised in spring, summer and autumn, and it is suitable to be carried out from early September to mid-October in autumn.

The nursery land should choose sandy loam or loam land with flat terrain, deep soil quality and convenient drainage and irrigation. Before raising seedlings, 5 cubic meters of mature organic fertilizer and 50 kg of calcium superphosphate or calcium magnesium phosphate fertilizer were applied per mu. After ploughing, rake flat and fine in time, and prepare the soil to make beds.

Cuttings should select 1-2-year-old strong, full branches, according to the length of the selected cuttings can be divided into short-branch cuttings and long-branch cuttings. Short-wood cuttings are often used for mass propagation of seedlings, while long-wood cuttings are often used for direct seeding or propagation of semi-finished seedlings. The length of long branch cuttings is 30 cm 40 cm, the length of short branch cuttings is about 25 cm, the thickness of cuttings is 0.5 cm 1.5 cm, each root has at least 3 nodes, the lower leaves are removed, the upper 2 leaves are left, the lower end is cut into a smooth bevel, every 50 cm 100 roots are tied into a small bundle, and the lower slope of honeysuckle cuttings is dipped in 500ppm indolebutyric acid solution for 5 seconds. Immediately after drying, the cuttings are cut on the flat rake bed. The long wood cuttage seedlings were trenched according to the row spacing of 30 cm, and the ditch depth was 25 cm. The introduction holes were made on the border surface with small wooden sticks or bamboo chopsticks every 3 cm, and then the cuttings length was obliquely inserted into the hole, compacted and pressed. This method can raise about 11000 seedlings per mu. The method of raising seedlings by short wood cuttings is roughly the same as that mentioned above, the distance between rows and plants can be reduced to 15 cm and 20 cm, and the seedlings can be raised by about 18000 plants per mu.

Cuttings should be watered once on the same day or the next day to keep the soil moist, promote its rooting and sprouting, and timely ploughing and weeding. It took root and sprouted in about 20 days, and the seedlings raised by cuttings in summer and autumn were transplanted in the following spring.

2. Striping to raise seedlings

Striping seedlings are often carried out in summer and autumn. The 3 ~ 4-year-old honeysuckle with flowering, strong growth and high yield was selected as the mother plant. The 1-year-old branch near the ground is bent and buried in the soil, cut it in the part of the branch, cover 10-15cm fine fertilizer soil, pay attention to keep the soil moist, and then fix and press the branch so that the branch tip is exposed to the ground. If the branch is longer, it can be bent continuously and pressed into the soil. Under the pressure of rear service watering and fertilization, the rooted striped seedlings can be cut off from the mother in the following spring and planted separately. Compared with the traditional cutting propagation, this method not only can blossom 2 ~ 3 years earlier, maintain stable yield and promote yield increase, but also has the advantages of convenient operation and high survival rate.
