How do potted miniature chrysanthemums overwinter? Master these overwintering methods
1. Soil burial, or burying the lower part in soil while covering the upper part with dry leaves. Before the frost season arrives, potted miniature chrysanthemums can be kept in their pots or removed from them, and for the burial covering use plain wet soil. First, it is forbidden to use fertilized soil or soil mixed with firewood, grass or leaves, because plain soil will not mold or generate heat that harms the chrysanthemum roots and plants. If the lower part is buried in plain wet soil and the upper part is then covered with dry leaves, even if the leaves become wet from snow they will dry out in the wind after sunny weather, and will not cause great harm to the chrysanthemum plants. Second, it is forbidden to keep watering after burying, because they are already buried in wet soil, and the miniature chrysanthemums lie dormant under the soil, neither growing nor consuming water,

How to control the jujube gall midge? Mastering these methods is key
Because the various life stages of this insect are relatively small, manual control is somewhat difficult, so chemical control is generally used, as follows: (1) Ground control: when the jujube buds are about to sprout (around mid-April), before the overwintering adults emerge, spray the ground under the tree canopy with 2.5% trichlorfon powder, or 25% phoxim capsule formulation at 200-300 times dilution (cover with fine soil or lightly hoe and loosen the soil to mix evenly), or 4% acephate powder, or 4% dibrom powder, all are acceptable; where there are seedling beds between the rows, spray the ground at the same time.

Methods to control excessive growth and promote sturdy wheat seedlings: these technical points must be mastered
When wheat seedlings grow excessively before winter, their growth period advances, nutrient accumulation decreases, and cold resistance drops, which is not conducive to safe overwintering. They can be managed by category according to the cause of excessive growth to control vigorous growth and promote sturdiness. 1. Vigorous seedlings formed by too-early sowing: the seedling leaves are slender, tillering is insufficient, and the main stem and some large tillers enter the double-ridge stage before winter. Such wheat seedlings are often vigorous early and weak later, and will be frostbitten in winter when exposed to a low temperature of minus 10°C lasting 5 hours. They should be pressed in a timely manner to inhibit the growth of the main stem and large tillers of the wheat seedlings and control spindly growth. Pressing should be done on a sunny morning; it must not be done when there is frost or dew

Autumn fishing has its finer points: these key tips you need to master
1. Pay attention to weather conditions: Autumn seine fishing must be done on a sunny day, when the weather is cool, around dawn before the pond fish surface for air, because at this time the impact on the pond fish is smallest, and the freshly caught fish can be supplied to the morning market in time. Hazy, muggy weather is not suitable for seine fishing, to avoid causing a large number of dead fish. In addition, when the pond fish are surfacing for air or there is fish disease, etc., it is also not suitable to seine and catch them. 2. Restrict feeding before catching: After fish eat their fill, their oxygen consumption increases, and when the net is drawn to catch them they will be startled, jump and dart away, which easily causes death

Detailed Explanation of Schisandra chinensis Seedling Cultivation Techniques, Master All the Key Methods
Schisandra chinensis, as a traditional Chinese medicinal herb, is the finest among the Schisandra species, mainly growing in the eastern mountainous areas of Liaoning Province. In recent years, the price of Schisandra has risen in the market, with supply falling short of demand. The main reasons are: first, as China joined the WTO, the export volume of traditional Chinese medicinal herbs increased, and market demand for Schisandra grew; second, with the development of animal husbandry, the wild resources of Schisandra have been damaged, especially since goats like to eat Schisandra. In the past two years, artificial cultivation of Schisandra has begun in Liaoyang, Dandong and other areas, but due to immature seedling cultivation techniques, many farmers cannot produce seedlings or have very low germination rates.
