Precautions for Spring Transport and Stocking of Fish Fry
Spring returns to the earth, water temperatures gradually rise, and it is once again the best time of year for transporting aquatic fry and fingerlings. During this period, because water temperatures are relatively low, fish are less active, and at the same time their bodies are firm and scales tight, so they are less likely to be injured during transport, which can increase the survival rate of spring stocking of fingerlings. There are many precautions in the spring transport and spring stocking of fingerlings, and fishermen friends are reminded to pay attention to them. 1. Pond disinfection should be carried out after removing excess sludge from the pond, reinforcing the pond embankment, and clearing the inlet and drainage ditches. Generally, for a dry pond, use about 200kg of quicklime per mu, slake it into a slurry, and

Four key points for fish farming at the start of spring
1. Fertilization: In early spring, when the pond water temperature stabilizes at 8°C to 10°C, start applying additional fertilizer to cultivate natural food organisms in the water. The amount of fertilizer should be determined based on the fertility of the water and the quality of the fertilizer. Generally, apply 60 to 90 kg of human and animal manure per mu, or 100 to 150 kg of livestock manure. If chemical fertilizer is used, follow a nitrogen-to-phosphorus-to-potassium ratio of 1:1:0.5. When applying, first crush it, mix it with water, and splash it evenly over the entire pond. The total amount per mu is 3 to 7 kg, with each application spaced 5 to 10 days apart. Keep the pond water a yellowish-brown or yellow

Detailed Explanation of Early Spring Management Measures and Technical Points for Peach Orchards
For early spring management of peach orchards, focus on ditching, supplementary fertilizing, gap filling, and applying eradication agents, which helps form strong buds and lays the foundation for high yield and quality peaches that year. 1. Clear ditches for smooth drainage. Low-lying terrain and heavy clay soil mean waterlogging damage is a major constraint on high yield and quality of peach trees. Especially since precipitation was low since the second half of last year, it is highly likely that rainfall will be excessive this year. If the ditch system in the peach orchard does not drain smoothly, severe waterlogging will damage roots and weaken tree vigor. Therefore, for the main drainage ditches and perimeter ditches of the peach orchard, labor should be organized for thorough clearing to

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.

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.

Key Technical Points for Spring Sesame Cultivation with Plastic Film Mulching
Plastic film mulching cultivation can bring sesame yields to over 150 kg per mu, and some can exceed 200 kg, so film mulching is an effective cultivation measure for achieving super-high sesame yields. The specific techniques are introduced as follows: 1. Seed selection and timely early sowing: After plastic film mulching, the effective growth period of sesame is extended. Therefore, mid-to-late maturing excellent sesame varieties with waterlogging tolerance, disease resistance, and high yield potential should be selected, such as Yuzhi No. 5, No. 7, No. 8, and sesame hybrids. Early sowing is suitable, with a sowing period from the end of April to early May, to fully utilize the growing season and increase sesame yield. 2. Land preparation

Land preparation and sowing methods for spring sesame and summer sesame
Spring sesame should adopt the "plowed furrow slice" method. The so-called "plowed furrow slice" means that after the previous crop is harvested, fertilizer is applied, the soil is plowed and harrowed, and then sesame is sown. The advantages of "plowed furrow slice" are: it can turn the soil and loosen it, increasing soil temperature; bury the base fertilizer, improving fertilizer efficiency; reduce weeds, making intertillage convenient; and the soil has good aeration, which can improve the soil's water storage and fertilizer retention capacity. Therefore, planting "plowed furrow slice" sesame is a key measure for increasing yield. For summer sesame, "iron stubble" sowing should be advocated, with rough sowing and careful management. "Iron stubble" sowing means that after the previous wheat crop is harvested, there is no further plowing, plowing or harrowing; as long as it is raked

Spring pig farming: pay attention to preventing vitamin deficiencies
Vitamin A deficiency: use 20 grams of pine needles, crush them for juice or boil them for juice, mix into the feed and give once, once a day, for several days in a row; you can also feed more carrots, silage and other feed rich in vitamin A. Vitamin B deficiency: when preparing daily feed, pay attention to fully supplying bran, silage, sprouted feed and others rich in vitamin B. If corn is used as feed for a long time, it can cause niacin deficiency. The amount of corn in the feed should be reduced and bran, silage, sprouted feed and juicy tuber feed should be increased.

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

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
