Five practical methods to protect wheat seedlings from freezing and cold
When the severe winter comes, doing a good job of protecting overwintering crops such as wheat from the winter cold and taking preventive measures is an important guarantee for obtaining a bumper harvest. According to different field plots, the following five methods can be used to prevent freezing and protect seedlings. First, spreading grass to protect seedlings. Some varieties with strong spring habit are sown relatively late, emerge sparsely, and have fewer tillers. For such field plots, cover them with crop straw such as wheat straw and rice straw to keep them warm, promote tiller growth, prevent freezing and strengthen seedlings, so that the wheat seedlings can safely overwinter. Second, applying fertilizer and water to the roots. For field plots where wheat seedlings have shallow roots and few tillers

How to manage a cotton field after a sudden shift from drought to waterlogging?
Right now, cotton is at the stage when vegetative growth is entering its peak and gradually shifting to reproductive growth, and it is also a period when the crop absorbs more fertilizer and water and is very sensitive. Since June 4, there have been many overcast and rainy days, the air humidity is very high, and the temperature has hovered between 25 and 30°C. Fusarium wilt has been triggered in many old cotton fields that have been planted for years. The rate of wilted plants is generally around 5%, in severe fields the rate of diseased plants is around 10%, and in some sections the incidence rate is around 20%. In some cotton fields, tarnished plant bugs, cotton bollworms, red spiders, and aphids are also causing damage in spots and patches.

Methods and Technical Key Points for Raising Black Locust Seedlings from Seed
Black locust is a pioneer tree species for afforestation on barren hills, with characteristics such as tolerance to poor soil, tolerance to drought, fast growth, and wide uses. 1. Nursery site selection and land preparation The seedling-raising site should be selected as level ground with good drainage, deep and fertile neutral sandy loam soil, and irrigation conditions. Vegetable plots must absolutely not be chosen, and continuous cropping is even less suitable. After the seedling-raising site is selected, plow it in autumn to a depth of about 30 cm. In early spring, harrow it fine and level, and apply 5000 kg of decomposed barnyard manure per mu. During land preparation, poisonous soil made from phoxim emulsifiable concentrate should be applied to control underground pests.

Can wastewater from snake pools be reused after treatment?
In the arid regions of the north, water resources are relatively scarce and limited. Especially in spring, when "spring rain is as precious as oil," draining the wastewater from the pool would be a waste, and besides, the flowers, grass, and trees at the snake farm all need water too. Why not reuse the wastewater? After all, the water in the snake pools (ditches) is generally changed quite frequently, so it would not reach a point where it cannot be reused. At my snake garden, I tried adding some oxidizing disinfectants and deworming drugs to the wastewater in the proportion for mixing with water, and after stirring evenly, I used it on trial as if it were clean water. The result was actually quite good, truly achieving two goals at once, with no harm to watering the grass, deworming, disinfecting, and retaining moisture.

The peel-off fragrant pear is a distinctive pear variety originating from the cold northern region.
In the past, we only knew that peaches could be peeled and eaten, and had never heard that pears could be peeled too. But now, Wang Shuyuan, an old horticulturist from Youyi County, through years of unremitting efforts, has crossbred and developed the Fragrant Pear (code name 12-7) whose skin can easily be peeled off entirely, and it is also of superior quality, cold-resistant and high-yielding. The 12-7 pear fruit is gourd-shaped, ripens on September 11, with yellow skin and a red blush on the sunny side, weighing 50-80 grams per fruit, with the largest reaching 150 grams. When first ripe it is of the sweet and crisp type; once it turns soft and fragrant, not only is peeling it easier than peeling a peach,

How to grow Dawn Redwood (Metasequoia glyptostroboides) from seed? A full breakdown of the key techniques
The techniques for growing Dawn Redwood from seed are: 1. Seed collection: Dawn Redwood flowers in early to mid-March, and the cones reach maturity from mid-October to early November of the same year. When the cone scales turn from green to yellowish-brown, crack slightly, and a small amount of seed falls out, the seeds are ready to collect. After the cones are collected, spread them out to air-dry or expose them briefly to the sun; the scales open and the seeds fall out. 2. Seed treatment: Before sowing, soak the seeds in cold water for 3 to 5 hours so they absorb water and swell fully, which aids germination and ensures even emergence. 3. Sowing: From late March to early April,

Detailed Explanation of the Key Techniques for Propagating Golden Privet (Ligustrum vicaryi) from Cuttings
I. Preparation of the cutting bed. First dig the cutting bed and firm the surrounding edges. Fill the bed with substrate in layers: spread 10 cm of cinder at the bottom layer to aid drainage, spread 10 cm of humus soil in the middle layer, and spread 5 cm of coarse sand on the top layer, then level the bed soil and set it aside. Finally, build an arched shed with bamboo strips and plastic. II. Cutting treatment. Select one-year-old branches cut from greening plots and roadside green belts, cut them into cuttings about 15 cm long, and keep 1-2 leaves at the top of each cutting. Because privet has dense axillary buds and a relatively high survival rate, no chemical solution treatment is needed before insertion. III. Inserting the cuttings.
