Experience sharing on forcing cultivation of tulips to bloom during Spring Festival
Tulips have strong cold resistance, tolerating low temperatures of -35°C in winter, and can grow normally at 5°C-8°C, making them suitable for winter forcing cultivation. Forcing cultivation of tulips means breaking the dormancy of flower primordia and leaf primordia through variable temperature treatment of the bulbs, eliminating factors that inhibit flower bud germination, and promoting flower bud differentiation, then through artificial heating, supplemental lighting and other measures, making tulips bloom outside their natural flowering period. Currently on the market there are commonly 5°C bulbs and 9°C bulbs; we generally choose 5°C bulbs for forcing cultivation to bloom during Spring Festival. Substrate

Detailed Explanation of Key Points for Spring Planting Techniques of Almonds
I. Cultivating Superior Seedlings. For almond rootstock, the own-root stock or peach rootstock is preferable; grafting onto apricot rootstock shows slow growth, poor healing, and stunted development, so it should not be used. Practice has proven that using almond as rootstock gives a high survival rate, good healing, high yield, and long lifespan, but slower growth. Using peach as rootstock (mountain peach or wild peach) gives a high survival rate and fast growth, but after healing the rootstock and scion diameters are inconsistent, and the lifespan is shorter (about 20 years). The seedling-raising method is basically the same as the technique for producing mature seedlings of common peach in the same year. Choose fertile, well-drained sandy

Potato Nutrient Pot Seedling Cultivation and Early Spring Greenhouse Cultivation Techniques
Potato under the long-term traditional cultivation model has a prominent phenomenon of high yield but low efficiency. Therefore, in recent years a new method of nutrient pot seedling cultivation and planting through plastic greenhouses has emerged, and good economic benefits have been achieved. 1. Cultivated varieties should be selected from early-maturing, low-temperature-tolerant, relatively high-yielding varieties, such as Dongnong 303 potato, which has stable quality and a growth period of about 90 days. 2. Land preparation and fertilization: in the autumn of the year before cultivating early spring potatoes, apply 6000 kg of decomposed farmyard manure and potassium sulfate per mu in the greenhouse.

Things to note when raising piglets in spring and summer, farmers should grasp them in advance
First, pay attention to temperature changes. In spring and summer, temperatures vary greatly, there is a lot of rain, and humidity is relatively high. Pigs prefer a dry environment, have little fat tissue, and piglets are prone to feeling cold. Therefore, the temperature inside the shed and the dry environment of the pen should be maintained. Second, pay attention to increasing protein feed. Especially for piglets that have undergone long-distance transport, due to stimulation such as wind-cold and the bumping of vehicles and boats, some piglets develop dysentery and diarrhea, reduced appetite, and weight loss. In addition to doing a good job of keeping the pen dry and warm, nutrition should also be supplemented in a timely manner.

Things to Keep in Mind When Selecting Fish Fingerlings in Winter and Spring
1. Pay attention to whether the fingerlings are uniform. If the fingerlings in the same pond vary in size, have relatively straight belly lines, thin and elongated tails, and slender bodies, then after being placed in a fish cage for 30 minutes they will show weak, sluggish movement, and some may even show symptoms of disease. Such fish cannot be stocked into ponds, nor are they suitable for long-distance transport; you may reduce the stocking density or move them to fertilized water for rearing. If they are indeed diseased, timely treatment is also needed. 2. Pay attention to the body length of the fingerlings. Whenever seining exercise is carried out, the fingerlings jump vigorously

How to manage greenhouse apricots in spring? Focus on management to promote development
For apricot trees in a winter-warm greenhouse, the fruit development period runs from mid-February to the end of April, and this period is divided into three main development stages. The first stage is the first rapid growth period of the apricot tree and the new shoot growth period, lasting 28-34 days; the second stage is the pit-hardening period, lasting 8-12 days; the third stage is the second rapid growth period of the apricot fruit and the new shoot growth period, lasting 20-30 days. Management work for the first stage: after flowering, apply 0.5 kg of nitrogen fertilizer and 1 kg of phosphorus fertilizer per tree, and within two weeks after flowering spray 0.3% urea once every 7 days. After leaf expansion, spray Yibianjing or Yashijing

Detailed Explanation of Key Points of Spring Potato Cultivation Techniques
Potatoes have the characteristics of high yield, early maturity, multiple uses and wide distribution, and in recent years the spring planting area in our region has been expanding year by year. 1. Land preparation. Potatoes prefer sandy loam and loam. Deep plowing and winter watering can be carried out before winter, with 2500-3000 kg of organic fertilizer applied per mu, and the land leveled before sowing with sufficient bottom moisture water. Through the shallow plowing and fertilizing method, 25 kg of potassium sulfate, 25 kg of diammonium phosphate and 15 kg of urea per mu are broadcast on the surface and worked into the soil with a rotary tiller. When ridging, the ridge width is 60 cm, the ridge height is 20-25 cm, and the ridge spacing is 100 cm.
