Detailed Explanation of the Key Scientific Cultivation Techniques for Purple Salvia
1. Overview Alias: Salvia miltiorrhiza, blood ginseng root. The root is used as medicine, to invigorate blood and regulate menstruation, for insomnia and palpitations. In modern medical clinical practice it is used to treat coronary heart disease, angina pectoris and other conditions with remarkable efficacy. 2. Biological Characteristics It prefers a warm, humid environment with abundant sunlight. At minus five degrees Celsius the stems and leaves suffer frost damage, while the underground roots are cold-resistant and can overwinter. High temperatures and drought during the seedling stage cause the seedlings to stagnate or even die. It is intolerant of waterlogging, and overly sandy, overly clayey or low-lying soils are unsuitable for planting. ⟦4 <p>1. Overview </p><p>Alias: Salvia miltiorrhiza, blood ginseng root.

At minus five degrees Celsius the stems and leaves suffer frost damage, while the underground roots are cold-resistant and can overwinter. High temperatures and drought during the seedling stage cause the seedlings to stagnate or even die. It is intolerant of waterlogging, and overly sandy, overly clayey or low-lying soils are unsuitable for planting. </p><p>3. Cultivation Techniques </p><p>1. Land selection and preparation. (1) Seedling plot: a plot with high terrain and loose soil. Make high beds and apply rotted barnyard manure or compost as base fertilizer. (2) Planting plot: choose a plot with deep soil, loose and fertile, relatively high terrain and good drainage for planting. (3) Mountain land: choose a sunny, low-slope plot. </p><p>2. Seedling raising. In late March, make beds 1.3 m wide, open furrows horizontally at a row spacing of 33 cm, with a furrow depth of 1 cm, mix the seeds with fine sand and scatter them into the furrows, cover with soil only to the extent that the seeds are no longer visible, cover with plastic film after sowing, punch holes in the film to release the seedlings after emergence, thin the seedlings when they are six cm tall, and transplant in late May. </p><p>3. Transplanting. Spring planting is done in mid-May, and autumn planting in late October. Earlier transplanting leads to earlier rooting and earlier greening in the following year. On the bed surface, dig holes at a row and plant spacing of 33× 23 cm, with the hole depth depending on the root length; apply base fertilizer at the bottom of the hole and plant 1~2 seedlings grown from seed (that is, seedling plants) per hole. </p><p>4. Seed propagation Same as seedling raising. </p><p>4. Field Management </p><p>1. Cultivation, weeding and topdressing Cultivate, weed, earth up and apply manure fertilizer three times a year. </p><p>2. Removal of flower buds To concentrate nutrients in the roots, all flower buds are cut off except in seed-production plots. </p><p>3. Drainage and irrigation Drain promptly during the rainy season and carry out furrow irrigation or watering promptly in dry weather. </p><p>5. Pest and Disease Control </p><p>1. Leaf spot disease Dark brown spots appear on the diseased parts, and in severe cases the leaves wither and die. For control, practice crop rotation; spray 0.3% potassium dihydrogen phosphate or carbendazim, thiophanate-methyl or zineb. </p><p>2. Root rot disease The lateral roots or fibrous roots turn brown and rot, causing the death of the whole plant. Irrigate with a 800~1000-fold solution of 50% carbendazim or a 1000-fold solution of 50% thiophanate-methyl. </p><p>3. Root-knot nematode disease Due to parasitism by root-knot nematodes, many tumor-like growths form on the roots, causing the plant to develop slowly and eventually the whole plant to wither and die. For control, rotate with cereal crops; apply 3% methyl isothiophos. </p><p>4. Silver-marked noctuid The larvae feed on Salvia miltiorrhiza leaves, and in severe cases the leaves are eaten bare. For control, burn the residual branches and diseased leaves after harvest; spray a 2000~3000-fold solution of 10% fenvalerate; a 1000-fold solution of 40% omethoate; or a 1000-fold solution of 90% trichlorfon to kill them. </p><p>6. Harvesting and Processing </p><p>For vegetatively propagated plants, dig them up in November of the same year or before sprouting in the following spring; for seed-propagated plants, they can be dug up from October to November of the second year to before sprouting in early spring of the third year. After digging them out, sun-dry them in the field, remove the soil and transport them back; do not wash with water. Dry them in the sun until they are fifty percent dry, tie them into small bundles, pile them for 2-3 days to let them sweat, then spread them out again and sun-dry until completely dry, remove the fibrous roots and trim the rhizome, and cut off the fine tail ends to obtain the commercial product.</p>

Detailed Explanation of the Key Points of Scientific Cultivation Techniques for Balloon Flower
Balloon flower (Platycodon grandiflorus) is widely cultivated in the river valley areas of Shangri-La County, and especially as prices have risen over the past two years, the planting area has increased year by year. Now I will provide a detailed introduction to the cultivation techniques for balloon flower, for the reference of the many farming households. 1. Site selection and land preparation: after choosing a sandy loam plot with sufficient sunlight, deep soil and good drainage, apply 3000 kg of farmyard manure per mu, plus 20 kg of superphosphate or 15 kg of diammonium phosphate, spread evenly over the land, plow deeply 25-30 cm, level and harrow finely, and make beds 1.2 m-1.5 m wide and 15 cm high, with length determined by the terrain.

What are the scientific methods for picking apples?
First, check the weather conditions. During the harvest period there is a lot of moisture; when there is dew, fog or raindrops, the fruit rots easily and does not keep well, so choose a sunny day to harvest. If forced to harvest in rain or fog, the picked fruit must be spread out in a ventilated place to dry. Second, harvest the fruit in order. When picking
