When is the best time to plant cherry blossoms? A detailed explanation of planting times
When is the best time to plant cherry blossoms, and how do you plant them? Can they be grown from root or branch cuttings? Reply: Cherry blossom propagation usually uses the high-grafting method or seed sowing: high grafting means wrapping the branch bark with a moisture-retaining material, waiting for roots to emerge, then cutting it off and planting it in soil; for seeds, first wash the flesh off the fruit, keeping only the seed, wrap it on damp cotton or a towel, and place it in the refrigerator to stratify; after about one month the seed will sprout. When transplanting, it is best to do so in winter; for seedlings on flat ground, pay attention to the temperature in summer

The best time for fattening geese is at the turn of autumn and winter.
Goslings raised in spring and summer grow into medium geese by late autumn and early winter. After medium geese are selected and evaluated, those that cannot be kept for breeding should be transferred to the fattening period in good time, to promote fast growth and weight gain, so the geese can be fattened in winter and sold on the market. The advantages of doing this: first, the weather in winter is cold, so after geese are slaughtered, they are not prone to spoilage and are easy to store; second, this is also when the Spring Festival approaches, when demand from the market and the public is large, sales channels are broad, prices are high, and the economic benefits of raising geese are good. The rapid fattening methods for geese are as follows: the fattening feed formula is 30% dried sweet potato, 40% corn,

Panax notoginseng seedling lifting time and seedling grading methods
The harvesting time for Panax notoginseng seedlings is generally from early December to late January of the following year. When harvesting, care should be taken to avoid damaging the root system and seed buds, and seedlings should be planted immediately after harvesting. Grade 1 seedlings: individual plant weight not less than 2.5 grams, dormant buds plump and strong, root system well developed, free from pest and disease infection and mechanical damage. Grade 2 seedlings: individual plant weight between 1.25 and 2.5 grams, dormant buds plump and strong, root system well developed, free from pest and disease infection and mechanical damage. Grade 3 seedlings: individual plant weight between 0.75 and 1.25 grams, dormant buds of average growth, root system of average growth, free from

Timely Control of White Peach Scale on Cherry Trees
White peach scale on cherry trees is mainly found in cherry-growing areas and occurs commonly. Because the current climate is suitable and field humidity is relatively high, it has occurred quite severely in some fields. The damage has already caused leaves to basically fall off, and the pest population is extremely dense; up close and from a distance it looks completely white. It is estimated that the first-instar nymph stage of white peach scale should be around the end of September. The first-instar nymph stage is the best time to carry out spray control. Growers should strengthen field inspections and apply pesticide control immediately if infestation occurs, keeping the pest population base below the allowable economic level. Control methods

Why Schisandra chinensis seedlings should be soaked in water before planting and the suitable soaking time
Schisandra chinensis seedlings naturally have indistinct main and lateral roots and many fine fibrous roots. After the seedlings leave the nursery, they go through several stages such as transport, storage and transplanting, and water loss occurs in both the root and crown areas. Using such seedlings results in a low survival rate, so before planting they should be soaked in water for 24 hours.

Detailed explanation of key points of mushroom preservation technology, easily extend storage time
Mushroom preservation methods include modified atmosphere preservation, low-temperature preservation, radiation preservation and brine preservation, etc. The methods are: modified atmosphere preservation uses simple modified atmosphere storage, within 3 to 5 days it can keep mushrooms fresh and tender without opening their caps, basically without browning, and with a water loss rate below 1%. At present, breathable plastic film bags are generally used for packaging, maintaining an oxygen concentration of 1% and a carbon dioxide concentration of 10% to 15% inside the bag, which can keep mushrooms white for 4 days with good freshness. Cold storage preservation: low temperature can keep mushrooms fresh and of high quality. During storage and transportation

It is the right time for honeysuckle pest and disease control, and Xiushan County, Chongqing Municipality is strictly implementing it
Honeysuckle, formerly known as Japanese honeysuckle, also called silver flower, honeysuckle flower, or double flower, is a twining vine of the Caprifoliaceae family. The county has developed a honeysuckle base of 60,000 mu. Because the base farmers manage extensively and supporting technologies have not kept up, especially pest and disease control management, the yield of honeysuckle is low and the quality is poor. According to a survey by the county plant protection station, honeysuckle pests and diseases occur relatively commonly in our county, among which honeysuckle powdery mildew, brown spot disease, aphids and red spiders are relatively serious in occurrence and damage. At present, it is the best period for controlling honeysuckle powdery mildew, brown spot disease, aphids and red spiders and other pests and diseases
