What are the propagation methods for growing Salvia miltiorrhiza (red sage)?
Seed propagation: Broadcast sowing is generally used, and sowing is best done from the year's Grain in Ear to Summer Solstice and from End of Heat to White Dew in the year the seeds are collected. The seedbed should be land with a slightly higher elevation, loose and fertile soil, and convenient watering. For raising seedlings in mountainous areas, it is best to choose a hillside slope at the foot of a mountain facing east or southeast as the seedbed, to reduce sun exposure and help seedling emergence. The seedbed should first be plowed, and decomposed human manure and urine used as base fertilizer. The soil should be broken up fine and made into high beds 1.3-1.66 m wide. Then the seeds are evenly broadcast shallowly on the bed surface; after sowing, press lightly once with the foot so the seeds adhere closely to the surface soil (no need to cover with soil), cover with a thin layer of wheat straw, and sprinkle water frequently to keep it moist. When the seedlings have 3-5 true leaves, thin them out if they are found to be too dense. The thinned seedlings can be temporarily planted elsewhere and cultivated. During this period, pay attention to watering and promptly apply 1-2 topdressings of dilute human manure and urine to promote seedling growth. The suitable time for transplanting is from late October to early November of the same year. Before transplanting, open holes on the prepared bed surface at a spacing of 25 cm × 25 cm, with the hole depth depending on the length of the seedling roots. Plant 1-2 plants per hole, with the planting depth such that the heart bud is slightly exposed; do not plant too deep, and do not let the root crown be exposed above the soil. After planting, cover with soil until the holes are level, press slightly firm, and water promptly to settle the roots. When Salvia miltiorrhiza is transplanted early, it takes root early, and by the time the cold winter arrives it has already survived, and it will green up early the following year; as far as possible, do not delay transplanting until the severe cold season.</p><p></p><p>Root division propagation:</p><p>Carry out from the Beginning of Spring to Awakening of Insects. Select robust new roots about 1 cm in diameter for planting. Before planting, first cut the roots into 5-7 cm long root segments. The planting density is 27 cm between rows and 20 cm between plants. Open furrows on the bed surface, place the root segments upright in the furrows, taking care not to place the upper and lower ends upside down, and after planting cover level with soil. Seedlings generally emerge after Grain Rain. With root division propagation, flowering is later, and it is difficult to harvest seeds in the same year, but the roots grow faster.</p><p>Division propagation:</p><p>From the Beginning of Winter to the Awakening of Insects of the following year, when harvesting home-grown Salvia miltiorrhiza (generally between the Winter Solstice and the Beginning of Spring), select robust, disease-free plants, cut off the thick roots for medicinal use, and use the roots thinner than a cigarette, together with the rhizome head and heart leaves, as planting stock for propagation. Wild Salvia miltiorrhiza can also be dug up and transplanted together with roots and seedlings. Large seedlings can be divided into 2-4 plants according to the natural growth conditions of the buds and roots, and then planted.</p><p>Cuttage:</p><p>Around Qingming, select thick, strong stems, cut them into sections with 2-3 nodes each, cut off part of the leaves, and insert them into the prepared bed, burying 6-10 cm in the soil, leaving the buds slightly exposed above the soil surface, press the soil firm, and water immediately. After that, spray water with a sprayer in the morning and evening to keep the bed surface moist.</p>

What issues need attention when growing licorice?
1. Seed treatment. Before sowing, treat the seeds with water at 60-100°C for 30 seconds; then soak them in warm water for 1 day and night, and the germination rate can reach 50%. If treated with concentrated sulfuric acid, remove the seeds immediately once the seed coat turns black and rinse them in clean water, then soak them in warm water, and sow when the seeds swell; the germination rate can reach more than 90%.

How to Prevent Fruit Cracking in Citrus? Growing Experience Shared
Citrus fruit cracking occurs every year, and it is most severe after the Mid-Autumn Festival, causing heavy losses for fruit growers. The main cause of citrus fruit cracking is unbalanced water supply. For example, severe cracking occurs after a long drought followed by heavy rain. The following measures can reduce the occurrence of fruit cracking.

How to Promote Coloring and Flowering in Citrus? Practical Cultivation Methods Shared
To achieve beautiful coloring and high fruit quality in citrus, the key is to apply phosphorus and potassium fertilizers early, because phosphorus and potassium help sugar accumulation and protein formation, and increase fruit coloring. Never spray fast-acting nitrogen fertilizer; with abundant nitrogen and vigorous tree growth, most photosynthetic products are converted into nitrogen-containing organic compounds

I. Ridge raising and mulching. 1. Dig fertilization pits (this can be done together with the application of base fertilizer). On the inner side, 30-40 cm vertically below the extended branches on the outer periphery of the tree canopy, dig 2-4 fertilization pits each 40 cm long and 40 cm wide and 50 cm deep (the depth for topdressing is 20 cm). 2. Dig trenches and raise ridges. Outside the fertilization holes, along the row direction

How to control crown gall disease of jujube trees with good results
This disease is a bacterial disease and occurs in jujube-growing areas in the north. After the roots are damaged, the aboveground growth is slow and the plants are stunted; in severe cases the leaves turn yellow and fall early, and the branches weaken or even die, but it rarely causes the whole plant to die. Besides harming jujube trees, the pathogen also attacks
