Why doesn't honeysuckle blossom?

Honeysuckle has been known as a good medicine for heat-clearing and detoxification since ancient times. Honeysuckle is a plant of honeysuckle family and the same genus of honeysuckle plants with dry buds or blooming flowers. It can spread wind and heat, and is also good at clearing blood poison. It is named because it turns yellow after it blossoms white at the beginning. It has a very wide range of medicinal value and health care uses. Let's take a look at why honeysuckle does not bloom.

When does honeysuckle blossom?

Honeysuckle usually begins to bloom in late May and ends around mid-October with a florescence of about 150 days. Usually, the first stubble blossoms in late May, the second in mid-July, the third in mid-August and the fourth in mid-October, and the flowering period of each stubble is about 7 days. The total pedicel of honeysuckle is usually solitary in the upper leaf axil of the branchlet, as long as or slightly shorter than the petiole, the Corolla is white, sometimes the base toward the sunny side is reddish, then turns yellow, lip-shaped, the tube is slightly longer than the lip, fragrant.

Why doesn't honeysuckle blossom?

1, lack of sunshine: honeysuckle needs good light conditions to grow well, can not be placed in a shaded place, long-term placed in a shaded place will lead to honeysuckle will not bloom.

2. Poor ventilation: if the planting space of honeysuckle is too small, the air is not ventilated and it is difficult to grow and develop well, so it is best to build a scaffold.

3. Soil phosphorus deficiency: when honeysuckle is planted, the lack of phosphorus in the soil will lead to non-flowering, so it is necessary to increase the amount of phosphorus and potassium fertilizer and control the amount of nitrogen fertilizer.

4. Reasonable pruning: when planting honeysuckle, if the pruning work is not done well, it will not blossom. At this time, weak twigs, disease and insect branches should be removed so that nutrients can be supplied centrally.

Planting and management technology of honeysuckle

1. Seed propagation: honeysuckle seeds are usually sowed in April. Soak the seeds in 35-40 ℃ warm water for 24 hours, remove 2-3 times wet sand to promote germination, and sow seeds when the crack reaches about 30%. Sow seeds in trenches according to the row spacing of 21cm to 22cm, cover soil with 1cm, spray water every 2 days, seedling can emerge in more than 10 days, and transplant after autumn or in spring of the second year, with seeds of about 15kg per hectare.

2. Cutting propagation: the cutting propagation of honeysuckle is generally carried out in the rainy season. In the rainy weather of summer and autumn, the sturdy, disease-free, 2-year-old branches are cut into 30cm and 35cm, and the lower leaves are removed as cuttings. On the selected land, the hole is dug according to the row spacing of 1.6 meters and the plant spacing of 1.5 meters. The depth of the hole is 16-18 cm, and each hole has 5-6 cuttings, which is scattered and obliquely standing in the soil. About 7-10 cm is exposed on the ground and the fill is compacted.

3. Timely pruning: pruning is carried out after falling leaves in autumn to before sprouting in spring, generally light pruning of strong branches, strong pruning of weak branches, and pruning of all branches. When pruning, attention should be paid to ventilation and light transmission after the new branches grow. The thin and weak branches, withered old branches and basal branches are all cut off, and the pruning of the plots with poor fertilizer and water conditions is heavier, and the old branches are cut off with the aging of the plant to promote the development of new branches. The young plants are mainly cultured plant type, which should be cut lightly. There are generally 4-5 trunk branches in mountain land and 1-2 trunk branches in plain land, and the trunk should be cut off slightly to make it thicker and upright.

4. Reasonable shaping: shaping is carried out in combination with pruning, which in principle is based on fertilizer and water management, promotes as a whole, makes full use of space, increases the amount of branches and leaves, makes the plant type more reasonable, and can obviously increase flower and high yield. The flowering time after pruning is relatively concentrated, which is convenient for harvest and processing. Generally, the branches can be upright after pruning, and the removal of thin and weak branches and basal branches is beneficial to the formation of new flowers. Cut the flowers after picking, apply quick-acting nitrogen fertilizer once after cutting, and water once to promote the next stubble flowers to grow early, so that flowers can be harvested four times a year, with an average dry flower yield of 150,200kg per mu.

5. Cultivate soil and weed: honeysuckle is planted 3 times a year for soil cultivation and weeding, the first time when new leaves are produced, the second time before the second flowering period, and the last time before frost in late autumn and early winter. The purpose of soil cultivation is to prevent the flower roots from exposing to the ground, and it is recommended to be carried out at the same time with fertilization. Weeding should start from the periphery of the flowers, far and then near, and be careful not to damage the root system.

6. Reasonable topdressing: within the first 1-2 years after planting, honeysuckle is the stage of plant development, with more fertilizers such as human and animal manure, plant ash, urea, potassium sulfate and so on. After 2-3 years of planting, more fertilizers such as livestock manure, barnyard manure, cake fertilizer and calcium superphosphate should be applied at the beginning of spring every year. Appropriate amount of nitrogen, phosphorus and potassium compound fertilizer should be applied after the first crop flower harvest to provide sufficient nutrients for the next crop flower. Every year after sprouting in early spring and when the first batch of flowers are harvested, open ditches are poured with human feces and urine, chemical fertilizer and so on, with 250 grams of each kind of fertilizer.

7. Harvest and processing: the best time for honeysuckle harvest is early morning and morning, when the flower buds are not easy to open, with sufficient nutrients, strong smell and good color. The harvest in the afternoon should end before sunset, because the blooming of honeysuckle is restricted by light, and the mature buds will open when the sun lags behind, affecting the quality. Without young buds or leaves, put them in a basket woven with strips or bamboo after harvest. Do not pile them in large piles when concentrated. They should be laid out and placed for no more than 4 hours at most.
