How to prevent and control the damage of hock coarse horn firefly to licorice
The leaf-eating pest of Chrysomelidae is one of the main obstacles to the development of licorice production. There are different degrees of licorice producing areas in the Uygur Autonomous region, Hexi region of Gansu Province and Liaoning Province, mainly harming sweet licorice rather than other trees, shrubs and other herbs. In the whole growing season, adults are the main damage, and the food intake is large, adults and larvae often overlap as damage, serious land occurs, the whole piece of licorice is eaten only stems or leaf veins, from afar it seems to be in the autumn withered and yellow defoliation period.

How to control the damage of underground pests to licorice
The main underground pests in the emergence stage of Glycyrrhiza uralensis are mole cricket, he's oriental chelate beetle, and the adult stage is mainly damaged by golden needle worm, beetle, ground tiger, pseudo-step beetle and so on. After the wild licorice is damaged by underground pests, because the wild root head is deep from the surface, the underground stem is mainly eaten. After damage, the adventitious buds can grow rapidly and regenerate without the death of the whole plant. On the other hand, the root is mainly damaged by the artificial cultivated licorice, and the young recovery ability of the plant is weak, accompanied by decay and infection, which often leads to the decay and death of the whole plant.

Cultivation and maintenance methods of Phyllostachys pubescens
1. The planting of Phyllostachys pubescens has many advantages, such as drought and water saving, alkali tolerance, barren tolerance, cold tolerance, long green period and so on. The following problems should be paid attention to when planting: 1. The soil of the planting site had better be sandy or semi-sandy, and sand mixing can be carried out in the clay area, which is beneficial to drainage and root growth. 2. Generally speaking, soil preparation only needs to plough the soil layer with a depth of 15 to 20 centimeters, pick up stones and rubble, and do not need to sift the soil and flatten the land before planting. If you encounter

Water-saving Ground Cover--Dianthus oxyphylla
Most areas in northern China belong to resource-based severe water shortage areas, with per capita water resources of less than 300 cubic meters, only 1/8 of the national average level, and far below the international water shortage limit of 1000 cubic meters per capita. With the vigorous development of landscaping, the water consumption of greening is increasing, which is in contradiction with the shortage of water resources in northern China. Dianthus oxyphylla has good drought resistance and is a good water-saving plant material in landscaping. After calculation, the annual water consumption of Dianthus oxyphylla per square meter is only 0.

Cultivation of Jintuan Carnation
Jintuan carnation is a herbaceous flower of Caryophyllaceae in 2012. it likes light and cold but is not resistant to heat and poor growth in summer. The inflorescence is fascicled, the flower color is bright, the height is about 70 cm, the cut flower is of good quality. First, sowing: you can sow in spring and autumn, and autumn sowing seedlings grow better than spring sowing seedlings. Sow seeds in the open field seedbed in September and cover with a thin layer of soil after sowing to keep the soil moist. It can germinate in about 7 days under the condition of 20 ℃ to 25 ℃, and the germination rate is more than 80%. Second, cultivation management: when the seedlings grow 4 pairs of leaves, they can be planted as cut flowers according to 15.

Breeding Management of Carnation in the United States
Propagation methods: sowing and cutting propagation. 1. Sowing and breeding can be done in spring and autumn. The seeds were sown in the open field from September to October in autumn. The optimum temperature for germination was 1-0: 20 ℃. American carnation seedlings need one and a half months of low temperature vernalization to differentiate flower buds, so they do not blossom in spring, but only grow leaves, and can not bloom until the early summer of the following year. It is suitable for seedlings to grow 2~3cm before frosting. Sow seeds in the field, sowing 200 seeds per square meter. If the seedlings are produced, they can be doubled to 400 per square meter after they are grown. Sow seeds in the greenhouse.

How to propagate Dianthus scientifically
Carnation can be propagated by sowing and tissue culture: ① sowing and propagation. First of all, the healthy and disease-free plant should be selected as the seed mother plant. When the capsule changes from green to light yellow, it is harvested, dried, and the seeds are scattered out, remove impurities and store them in a dry and ventilated place. In the Yangtze River valley in the south, most of the seeds are sown in March, and after the seeds are germinated and unearthed, the seedlings must be carried out to enlarge the gap between the seedlings in order to ventilate and penetrate the light, so that they can grow healthily; they can also be sowed on the cultivation seedling bed directly according to the row spacing of 20cm × 40cm, for maintenance and management. Sown during this period

How to cultivate Carnation scientifically
Carnation is mostly propagated by sowing and sowing in September at a temperature of 12: 18 ℃ and can emerge in about 10 days. It can also be propagated by cuttings, cutting 6 cm long branches as cuttings. It is best to choose 7 parts of garden soil and 1 part of compost soil for potted plants. The culture soil mixed with 2 parts of sandy soil can be transplanted into a small flowerpot with a diameter of 6 cm and 8 cm when the seedlings grow to 4 leaves. After growing into a large seedling, it can be planted in a flowerpot with a diameter of 15 cm and cultured in a place with sufficient sunlight. During the growth period, the flowers will be irrigated with fertilizer and water every 10 to 14 days.

Sowing and raising seedlings of Dianthus chinensis
Dianthus caryophyllus is a perennial herb of the family Caryophyllaceae. It has a wide variety of flowers and colors, and is mainly sexual reproduction. When raising carnation seedlings, choose a flat and dry place with 15 kilograms of compound fertilizer, deeply turned, smashed and leveled and sealed a 1-meter-wide bed. Irrigate once and sow the seeds immediately after the water seeps. After sowing, cover with a layer of fine soil, build a small arch shed, cover with plastic sheeting, the suitable temperature in the shed is 20 ℃ to 26 ℃, so that seedlings can emerge in about 10 days. After emergence, attention should be paid to ventilation to prevent flourishing and growing, so as to achieve seedling refinement.
