Detailed Explanation of the Fertilizer Requirement Patterns of Lilies Throughout the Growing Period
Understanding the fertilizer requirement patterns of lilies at each growth stage is very beneficial for rational fertilization and promoting high yields. The patterns of lily demand for the three major nutrients: 1. Nitrogen fertilizer: The nitrogen absorption rate of lilies varies at different growth stages. At emergence, the nitrogen absorption rate is 3.5537 probit units, and the cumulative nitrogen absorption percentage is 7.4%, equivalent to 0.201 kg of nitrogen absorbed per mu. This indicates that during the seedling stage, in addition to receiving nutrients from the mother bulb, the plant also needs to absorb a certain amount of nitrogen from the soil. 2. Phosphate fertilizer: At emergence, the phosphorus

How to Add Value to Sweet Potato and Rice Through Processing
Sweet Potato Starch Production Technology Wash the sweet potatoes, drain the water, crush them into pieces about 2 cm in size with a crusher, feed them into a stone mill or electric pulp grinder, add 3 to 3.5 times their volume of water, and grind into a starch slurry. Pour the starch slurry into a sieve with a mesh size of 60 and sieve out the potato residue to obtain starch milk. Place the starch milk in a settling tank and let it stand overnight so that the starch settles to the bottom of the tank. Drain off the supernatant, take out the crude starch, repeatedly rinse and settle it with clean water to obtain pure starch, then sun-dry, crush and sieve the starch to obtain

What is ground bed cultivation of Gastrodia elata? Let us walk you through this cultivation method
In low-lying flat land with a high water table, relatively low temperatures, and damp, rainy conditions, or when cultivating Gastrodia elata on a small scale in a new area, this planting method can be used. Bed cultivation is also divided into two methods: single-layer planting and double-layer planting. ① Single-layer planting method: Level the ground and make a bed 60-70 cm wide; the bed length depends on the terrain and the amount of Gastrodia elata to be planted. On the leveled bed surface, first spread a 2-3 cm thick layer of base culture material, then lay the fungus logs horizontally with a spacing of 6 cm. On both sides of the fungus logs, first add culture material up to half the height of the logs,

What Is Osteochondrosis in Dogs? Let Us Walk You Through This Disease
Osteochondrosis is a disease characterized by bone necrosis and impaired bone development in young dogs that are still in the growth and development stage. Examples include osteochondritis dissecans of the shoulder joint, osteochondrosis of the elbow joint, ununited anconeal process, and osteochondritis dissecans of the knee joint. [Causes] The cause is not yet clear. It is generally believed that the direct causes are circulatory disturbances or excessive traction and compression trauma. Endocrine dysfunction, malnutrition, and genetic factors are also related to the occurrence of this disease. [Symptoms] Osteochondritis dissecans of the shoulder joint is more common in large

New breakthrough in the treatment of self-biting syndrome in foxes, raccoon dogs and minks
Self-biting syndrome is a common disease of captive fur-bearing animals such as foxes and minks. In recent years, it has occurred in many farms and households in China, causing great economic losses. There had been no specific prevention or treatment measures for this disease, and the key point was that the cause had not been identified. Regarding the cause, people had put forward many hypotheses or claims, but these had not truly served to guide prevention and treatment. Since the early 1990s, researchers have carried out some research work on the cause of the disease. In the course of research and experiments, the cause of self-biting syndrome was identified,

Technical points for achieving early high yield through close planting of honeysuckle
Honeysuckle (Lonicera japonica) is a perennial semi-evergreen woody vine, also known as erhua or shuanghua, and is a traditional valuable Chinese medicinal herb. The roots, stems, leaves and flowers of honeysuckle can all be used medicinally, but the main medicinal part is the dried flower buds, which have the effects of clearing heat and detoxifying, eliminating chronic inflammation and improving human immunity. In recent years, with the intensification of honeysuckle development and the broadening of application fields, market demand has grown ever larger. Improving cultivation techniques to increase the early-stage yield of honeysuckle and maintain the duration of the full-yield period has become a major problem urgently needing solution in production. In recent years, based on

Shiitake mushrooms achieve three-dimensional cultivation through shelving
In recent years, my family has always been growing shiitake mushrooms in a greenhouse, but perhaps due to technical and other reasons, the returns have never been ideal. I heard that shelf-layer cultivation of shiitake mushrooms can bring considerable returns. Could you introduce the shelf-layer cultivation method for shiitake mushrooms? Tian Shuzhen, Nong'an. Hello Tian Shuzhen: Shelf-layer cultivation of shiitake mushrooms is currently a new technique for increasing shiitake mushroom yields. Below I will introduce how to choose a good site and variety, and the management points to note, for your reference: 1. Site and setup for the mushroom shed site

How to safely overwinter shiitake mushrooms through summer? These management points must be mastered
The quality of summer management for shiitake mushrooms directly affects yield and profitability. Doing a good job of summer management is a key step in shiitake mushroom production, and two methods can be used: indoor and outdoor. I. Indoor spawn running for summer survival (1) Minimize the number of shiitake bags indoors and the number of bag layers. Stack two bags in a cross pattern, with no more than 5 layers at most, and keep the spacing between stacks at more than 20 cm to facilitate ventilation and heat dissipation. (2) Build a shade canopy outside the window so that sunlight does not shine directly onto the window or indoors. (3) In hot weather, close doors and windows at 7 a.m. to prevent outside hot air from entering indoors, and in the evening

Important breakthrough made in hybrid japonica rice breeding
On the 18th, the reporter learned from the Shanghai Academy of Agricultural Sciences that agricultural scientists in Shanghai have made a breakthrough in hybrid japonica rice breeding in the Yangtze River Basin. Following the acquisition of the first hybrid late japonica rice restorer line in the Yangtze River Basin to obtain national plant variety protection rights, the first southern hybrid late japonica rice combination to pass national variety approval has also been bred. At present, a series of strongly heterotic combinations have become an important support for the "seed source" of hybrid japonica rice in the Yangtze River Basin. Researchers from the Crop Breeding Institute of the Shanghai Academy of Agricultural Sciences used intermediate materials between indica and japonica subspecies as "bridge parents"

Detailed Explanation of Technical Measures for Safely Overwintering Shiitake Mushroom Logs Through Summer
Key Management Points for Safely Overwintering Mushroom Logs Through Summer. Outdoor summering. Outdoor shade shelters have good ventilation and cool down quickly, therefore, using outdoor shade shelters for mycelium running can effectively reduce the occurrence of "mushroom burning." Specific measures taken for summering and mycelium running using outdoor shade shelters: First, build trellises around the shade shelter and plant vine crops such as pumpkins and luffa to improve the shading effect; Second, install automatic rotating tap water sprinklers or spray pipes on the shelter roof, and spray water to cool down from 10 AM to 4 PM every day; Third, dig interconnected trenches 20 cm wide and 30 cm deep around the inside of the shelter and on both sides of the walkways, and run flowing water through the trenches to cool down.
