How should Schisandra chinensis seedlings be planted to improve the survival rate?
Some people, when planting seedlings, just drop the seedling into the hole and cover it with soil, and that is it. This planting method is not good and affects the survival rate. The normal way to plant a seedling is to smooth the bottom of the dug hole with your hand, spread the seedling roots out to 120° when planting, and make sure all the roots are in close contact with the soil, firm it down, and water thoroughly. When planting Schisandra chinensis in autumn, prune the seedling to leave 3-5 buds, and after planting bury all the buds in soil; the top of the seedling should be covered with 4 cm of soil. When it is about to sprout in spring, remove the soil, or leaving the soil in place is also fine, letting the buds emerge from the soil. Remember, under no circumstances should you remove the soil after the buds have sprouted but before they have emerged,

Analysis of the Key Points of Integrated High-Yield Technology for Rainfed Soybean
I. Basic Information: 1. Project source: One of the projects under the "Comprehensive Technical Research on Increasing Production in the Sanjiang Plain Agricultural Region" issued by the National Science and Technology Commission during the "Sixth Five-Year Plan" period. A national key research project. 2. This project was reviewed in December 1985 by an appraisal committee composed of 20 experts and scholars including famous professors Wang Jinling and Zhang Zijin from China's soybean science community. The appraisal concluded that the research direction was correct, the approach was right, the measures were appropriate, and the results were remarkable, with an obvious yield-increasing effect on subsequent crops as well. Breakthrough progress had been made in integrated research and supporting technologies,

Cyanobacteria in mussel ponds tend to overproliferate in midsummer; pay attention to prevention and control
Summer has high water temperatures and strong light, making it a season of high cyanobacteria incidence. Once cyanobacteria proliferate heavily on the water surface, the water quality becomes lean; after pearl mussels ingest cyanobacteria, it is not easy for them to digest (cyanobacteria have thick cell walls), and cyanobacteria adhere to the mussels' gills, affecting respiration. At the same time, after cyanobacteria die, protein decomposition produces hydroxylamine, which combines with toxic substances such as hydrogen sulfide in the water and can poison the pearl-culturing mussels to death. Therefore, in summer, the excessive proliferation of cyanobacteria must be strictly controlled, with targeted prevention and treatment. 1. Summer temperatures are high, and at the bottom

How to increase the survival rate when propagating geraniums
Geraniums are mainly propagated by cuttings. To increase the survival rate, you must master the following points: (1) Selection of cuttings. Choose branches that are solid inside and have a small cut surface as cuttings. The specific method is to pinch off the growing tip of the mother plant in advance, and after new side branches emerge, cut the branch from the base of the new side branch, close to the mother branch. (2) Cutting time. Cuttings are generally taken in mid-September. If the cuttings are not newly grown side branches, the cut cuttings must be left to dry for at least a whole day.

How to use fermentation aids in mushroom cultivation substrate
Using fermentation aids to make edible mushroom substrate has the characteristics of fast fermentation, thorough fermentation, being able to ferment at both high and low temperatures, greatly shortening the conventional fermentation production time, reducing labor intensity, and lowering costs; it also has the characteristics of "broad-spectrum" fermentation (it can ferment almost all organic materials that need fermentation) and "strong adaptability" (it has relatively loose requirements for environmental conditions). Comparative trial demonstrations of the Jinbaobei edible mushroom cultivation substrate fermentation aid produced by Beijing Huaxia Kangyuan Technology Co., Ltd. show that this fermentation microbial agent is more

Occurrence and Integrated Control Methods of Sheep Nasal Bot Fly
Cause: Sheep nasal bot fly is a disease caused by the larvae of the sheep nasal bot fly parasitizing the nasal cavity of sheep, mainly affecting sheep (Ovis aries). The adult sheep nasal bot fly directly deposits larvae, and the larvae become adults after passing through the pupal stage. Adult sheep nasal bot flies appear from May to September each year. After mating, the male fly dies, and the female fly rests until the larvae inside her body develop before flying and becoming active, depositing maggots in the nostrils of sheep to breed larvae. The first-stage larvae attach to the nasal mucosa of sheep and gradually migrate inward, molting into second-stage larvae in the nasal cavity and frontal sinuses, and by the spring of the following year, they develop into mature third-stage larvae.

Full Analysis of the Key Technical Points for Lotus-Rice-Fish Integrated Farming
"Lotus-rice-fish" integrated farming refers to a co-culture model in which both rice is planted and fish are raised during the growing period of lotus root. The relevant integrated farming techniques are briefly introduced below. 1. Reasonable site selection. Choose gray mud fields with sufficient water sources, strong water retention capacity, and medium or above fertility. Fields with water-quality concerns, cold-waterlogged fields, and perennial lotus fields are not suitable for selection. 2. Select improved varieties. For lotus seeds, choose excellent varieties with large grains, a long flowering period, and high yield; for rice, it is advisable to choose early-maturing or early-to-medium-maturing varieties, such as Minke Zao No. 8, Zhefu 218, etc.; for fish, mainly stock common carp.

How to mitigate continuous and alternate soybean cropping? Integrated measures are key
To minimize yield losses from continuous and alternate cropping, continuous and alternate soybean planting should be avoided as much as possible, rational crop rotation should be maintained, alternate cropping should be reduced, and continuous cropping should be controlled. In the long term, the area of continuous and alternate soybean cropping should not be expanded without limit, so as to avoid declining soil productivity and creating a vicious cycle. When continuous and alternate cropping is unavoidable, alternate cropping should be arranged first, and continuous cropping should be used only when alternate cropping cannot be arranged, and continuous cropping must not exceed two years. In response to the causes of yield reduction under continuous and alternate cropping, with emphasis on regulating nutrition and controlling pests and diseases, existing scientific

Integrated fish-and-goose farming model boosts farmers' income by 30 percent
Mixed farming of fish and geese is, for fishermen, a scientific farming model with "ten benefits and not a single drawback." This model makes full use of water surface and land resources, and under the same conditions increases economic returns by up to 30% compared with raising fish or geese alone, making it an effective new path to prosperity for fishermen. Advantages of integrated fish-and-goose farming: geese are fully automatic, energy-saving and highly efficient aerators for fish ponds. When fish and geese are raised together, farmers need not worry about oxygen depletion in the water caused by weather changes, because in low-pressure weather geese will rush to jump into the water, bathe and chase each other, churning up the water

What to Do About Low Hatch Rates in Female Turtles? Cause Analysis and Solutions
Artificial turtle farming has sprung up in many places in recent years, especially as the soft-shelled turtle market has flattened while the turtle market has held firm, prompting many soft-shelled turtle farmers to switch to turtles. But farmers have found that although some female turtles lay a good number of eggs, the fertilization rate is not high and the hatch rate is low, especially with eggs from turtles at their first laying age, where the fertilization rate is even lower. Many people assume the female turtle is the problem, little realizing that the cause does not lie with the female turtle at all, but is mainly related to factors in the male turtle itself. Through practice, people have found that in nature many animals show differences in the timing of sexual development
