What disasters should be prevented in spring strawberry planting?
How should strawberries be top-dressed with fertilizer? Please advise. Strawberries like fertilizer and have a relatively high fertilizer requirement, needing to absorb a large amount of nutrients from the soil each year. According to estimates, for every 750 kg of fruit harvested per mu of land, 10 kg of pure nitrogen, 2.5 kg of phosphorus, and 10 kg of potassium are needed. Top-dressing promotes early growth. On the premise of applying sufficient organic fertilizer, when the soil thaws...

How to remedy wheat after a spring frost
Every year in February and March of spring, cold air often breaks out and moves southward in the north, with a large temperature drop during the process, and wheat that has jointed too early often suffers frost damage. At this time, for seedlings growing too vigorously, the method of pressing should be adopted to inhibit growth; for weak seedlings, reasonable topdressing should be applied to promote weak ones into strong ones, so as to enhance cold resistance, and at the same time attention should be paid to listening to the weather...

Four protection measures for wheat spring field management
I. Occurrence and harm of wheat sharp eyespot. Wheat sharp eyespot is a fungal disease mainly transmitted through soil. With the improvement of yield levels, the promotion of high-yielding varieties, and wheat field management with heavy water and heavy fertilizer, its harm has become increasingly serious. The pathogen of wheat sharp eyespot has a wide host range; besides infecting wheat, it can also...

Spring Occurrence Patterns and Control Methods of Wheat Sharp Eyespot
Wheat sharp eyespot is a fungal disease mainly spread through the soil. As yield levels have increased, with the promotion of high-yielding varieties and wheat field management involving heavy watering and heavy fertilization, its damage has become increasingly serious. The pathogen of wheat sharp eyespot has a broad host range; besides infecting wheat, it can also infect corn, rice, foxtail millet, sorghum and many other...

Technical Guidance on Spring Fertilization Management for Wheat
1) Spraying paclobutrazol. At the wheat stem elongation stage, spraying 30 kg of 200 ppm paclobutrazol solution per mu can dwarf the plants, enhance lodging resistance, and also control wheat powdery mildew and improve the plant's nitrogen uptake and utilization rate. (2) Spraying chlormequat chloride. For wheat fields with large populations and vigorous growth, at the early jointing stage, spray per mu 0....

What are the spring lodging prevention measures for wheat? Explained clearly in one article
Lodging is one of the main factors affecting high and stable yields and good quality in wheat. Wheat lodging mainly occurs in high-yield wheat fields with ample fertilizer and water, excessive wheat growth, overly large populations, and dense, shaded field conditions. Early spring is the key period for preventing wheat lodging, and its comprehensive lodging prevention technical measures are: scientifically manage fertilizer and water. For high-yield wheat fields with a population of more than 650,000 plants per mu at the green-up stage, wait until the first internode of wheat has reached its final length (that is, late jointing stage), then apply topdressing and irrigation, applying 7.5-10 kg of urea per mu. This can reduce ineffective tillers, lower the length of basal internodes, promote thick and strong stems, and prevent lodging later, while also increasing grain number per spike and improving quality.

Key Technical Points for Spring Field Management of Dryland Wheat
I. Causes of Wheat Seedling Death in Winter and Spring 1. Internal causes refer to the ability of the wheat plant itself to resist cold and drought. Using varieties with poor cold resistance easily leads to seedling death. In individual cases, wheat seedlings sown too early that have reached the two-glume stage of spike differentiation before winter have weakened cold tolerance and often suffer severe seedling death when exposed to freezing injury. Some late and weak seedlings, having accumulated...

Current Wheat Growth Analysis and Spring Management Recommendations
Seven parts sowing, three parts management: improving sowing quality is the key to a bountiful grain harvest. At present, spring wheat in our province is about to enter the sowing period. How well we manage the sowing stage and improve sowing quality bears on the overall prospects for a bumper spring wheat harvest all year. 1. Select good varieties. To achieve a high wheat yield, soil is the foundation, fertilizer is the nutrition, and water is the lifeline, ...

Spring disease, pest and weed control in wheat enters a critical period
If disease centers are found in the field, spray promptly to control them. If the diseased leaf rate reaches 5% and the severity is below 10%, use 50 g of 15% triadimefon wettable powder per mu, or 40 mL of 20% triadimefon emulsifiable concentrate per mu, or 30 g of 25% triadimefon wettable powder per mu, or 15-30 g of 12.5% diniconazole wettable powder per mu, ...

Key Techniques for Spring Control of Wheat Sharp Eyespot
Wheat sharp eyespot is a fungal disease mainly spread through the soil. With the improvement of yield levels, the promotion of high-yielding varieties, and wheat field management with heavy irrigation and fertilization, its damage has become increasingly serious. After wheat sowing, if the germ is infected by the pathogen during germination, the coleoptile turns brown, and in severe cases rots and dies; after the standing and jointing stages, the diseased plant rate rises significantly...
