Chimonanthus is a traditional and valuable ornamental plant in China, also known as Chimonanthus, Chimonanthus and Chimonanthus. It is a deciduous shrub plant of the genus Chimonanthus of the family Chimonanthus. The flowers are fragrant and beautiful, suitable for planting in the courtyard, and suitable for ancient pile bonsai and flower arrangement and plastic arts. Its roots and leaves can also be used medicinally. Let's take a look at the seed price and planting method of Chimonanthus.

How much is the preserved plum seed per jin?

The price of preserved plum seeds is about 80,120 yuan per jin, but the price varies greatly due to the variety, quality and quantity of seeds. Chimonanthus is native to central China and likes sunshine, but it is also slightly shade-resistant, cold-resistant and drought-resistant. It is said that it is an immortal wax plum. The requirement of soil quality is not strict, but the light loam with good drainage is suitable, and the cultivated varieties are Chimonanthus chinensis, diesel heart Chimonanthus, Goushou Chimonanthus and so on.

When will the seeds of preserved plum be planted?

1. Spring sowing: soak in warm water for 24 hours in spring, put it in a budding box to promote sprouting, then strip in the sandy soil and pour enough water, the seedlings can emerge in 15-20 days.

2. Autumn sowing: it is usually harvested after the fruit is ripe from July to August, the seeds are taken out from the receptacle, sown at any time, and seedlings can emerge more than 10 days after sowing.

What are the planting methods of preserved plum?

1. Open-field planting: before sprouting in spring, select neutral or slightly acidic sandy soil with deep soil layer, shelter from the wind and good drainage, and put rotten stable fertilizer and bean cake at the bottom of the hole as base fertilizer. After covering a layer of soil on the base fertilizer, the plants with soil balls are put in, filled, stamped and watered.

2. Bonsai cultivation: choose loose, fertile and well-drained sandy soil as culture soil, put a layer of gravel on the drainage hole at the bottom of the basin, dig and plant in the basin with small plants with full buds in early winter, and display and watch after flowering. Usually put it in a sunny place for maintenance.

Planting and Management methods of Prunus mume

1. Watering: Lamei is usually watered to maintain the soil moisture, pay attention to drainage in the rainy season, timely watering in the dry season, keep the soil moderately dry during flowering, and should not be watered too much. Potted Chimonanthus praecox is not dry or irrigated in spring and autumn, and is watered every morning and evening in summer.

2. Fertilization: the rotten organic fertilizer was applied once after the flower blossom was shed, the rotten cake fertilizer was applied every 10-15 days from the new leaf germination in spring to June, the mixture of rotten organic fertilizer and phosphorus and potassium fertilizer was applied in the flower bud differentiation period from July to August, and the organic fertilizer was applied again after autumn.

3. Plastic surgery

① Arbor shape: leave a sturdy branch in the seedling stage without coring to cultivate the trunk, when the trunk reaches the expected height, pick the core to promote the branch, when the branch grows to 25 cm, pick the heart again to form a crown, and cut off the branches germinated at the base at any time.

② clump shape: plum seedlings pick heart to promote its branches, strong branches cut off shoots in dormant period after crown cluster is formed, weak branches leave 2-3 buds at the base for truncation, the new branches are coring once in the first and middle June of that year, and regular pruning should be maintained after basic setting.

4. Pruning

① wiping buds and coring: the extra buds that are dense, introverted and close to the ground should be wiped out when the leaf buds germinate about 5 centimeters, and the exuberant growth period from May to June should be carried out to cut off miscellaneous branches, useless branches, irregular branches and wind shading branches in time in the rainy season.

② pruning before flowering: leave one more pair of leaf buds on the flower buds on the long branches before the flower buds expand after defoliation, cut off the upper part without flower buds, and remove withered branches, disease and insect branches, over-weak branches and dense, overgrown non-flowering branches and roots that are not used for renewal.

③ pruning after blossom: after wax plum blossom, old branches, withered branches, overdense branches and overgrown branches should be thinned, and weak main branches or groups of branches should be retracted. For over-tall, over-long and over-strong main branches, they can be retracted at larger oblique branches to control branch height, branch length and branch strength.

6. Diseases and insect pests

① anthracnose: thoroughly remove diseased leaves, centralize destruction, reduce infection sources, spray 50% methyl topiramate 800 × 1000 times, or 50% carbendazim wettable powder 1000 times.

② black spot: clear the fallen leaves, destroy centrally, reduce the source of infection, spray 50% carbendazim wettable powder 1000 times, or 65% Dysen zinc 500 times, or 0.3 Baume stone sulfur mixture.

③ aphids: cut off the oval branches, centrally destroy them, spray 10% imidacloprid wettable powder 6000 times, or 70% aphid-killing wettable powder 1500 times, or 50% marathon EC 1000 times 1500 times.

④ red-necked longicorn beetles: hit the branches with sticks to kill the adults in time, stab the larvae with wire when they find a faecal hole, or insert cotton balls dipped in dichlorvos into the defecation hole, seal it with yellow mud and fumigate.

⑤ Japanese tortoise wax scale: spray 2.5% enemy kill or kung fu EC 4000 × 5000 times, 10% cypermethrin EC or 20% fenvalerate EC 3000 times.
