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

What are the methods for improving the smoothness of apple fruit skin?
1. Fruit bagging. Fruit bagging is one of the best and most effective technical measures for improving the smoothness of apple fruit skin. Fruit bagging can make the skin smooth and delicate, with bright color, fewer russet spots, and small and few fruit dots, thereby improving the appearance quality of the fruit. 2.

Control Methods and Technical Key Points for Apple Little Leaf Disease
Apple little leaf disease occurs mostly in orchards with poor soil and good permeability. Because of low zinc content, soluble zinc salts leach away and the disease becomes severe; frequent watering and rainfall cause large losses of soluble zinc; excessive nitrogen fertilizer use increases the tree's zinc requirement; in saline-alkali soil the pH

What are the control methods for apple fruit cracking disease?
In the late stage of apple growth, fruit cracking disease is common and causes relatively serious damage, severely affecting the commercial value of apples and deserving sufficient attention. Apple fruit cracking disease is caused by slow expansion of fruit flesh cells during the early drought period of apple growth, and rapid cell expansion when rain occurs in the middle and late stages of apple growth

Detailed Explanation of Licorice Propagation Methods and Cultivation Techniques
Licorice propagation has three methods: seed propagation, rhizome propagation and division propagation. 1. Site selection and land preparation: Sandy soil and loose red loam soil are suitable; apply 2500 kg of farmyard manure per 667 sq m, deep plow 40-50 cm in autumn, harrow fine and level, and make high ridges 40-50 cm wide with furrows 30-35 cm wide.

What are the disease prevention and control methods for licorice cultivation?
The main diseases of licorice are: rust, brown spot and powdery mildew. The prevention and control methods are as follows: 1. Rust: when infected, yellowish-brown scar-like lesions appear on the underside of the leaves; after the epidermis ruptures, brown powder is released, which is the uredinium of the pathogen; in August-September, dark brown telia

Detailed Guide to Licorice Planting Methods and Cultivation Experience
1. Site selection and land preparation. Usually choose sandy loam soil that is fertile, loose in texture, well-drained, and low in salinity and alkalinity. Usually when preparing the land, a tractor is used to plow the field, with deep plowing of about 20 cm. At the same time, apply 2000-2500 kg of barnyard manure per 667 sq m as base fertilizer, then level and harrow finely.

Control Methods for Leaf Spot Disease in Balloon Flower Cultivation
Balloon flower (Platycodon grandiflorus) is a perennial herbaceous medicinal plant, with its roots used as medicine. The control methods for leaf spot disease in balloon flower are as follows: 1. Symptom identification: This type of disease mainly damages the leaves of balloon flower. (1) When infected by the septoria leaf spot pathogen, white circular or nearly circular lesions appear on both sides of the leaves,

Sharing Experience and Methods for Platycodon grandiflorus Planting and Seedling Cultivation
Since Platycodon grandiflorus was domesticated from wild varieties into cultivated ones, root branching and plant lodging have become bottlenecks hindering production and planting. Especially since the 1980s, with large demand from countries such as South Korea and Japan, the standard requires fresh Platycodon grandiflorus roots to have a diameter above 1.2cm, a length above 15cm, and no branching.

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>
