High-yield Cultivation Experience and Methods for Rainfed Spring Wheat
Dead wheat seedlings in winter wheat refers to the freeze damage that occurs during overwintering and early spring due to low temperatures, and it is one of the common disasters in wheat production. To achieve high and stable wheat yields and the goal of high quality and increased efficiency, it is essential to ensure a reasonable wheat population and a sufficient number of spikes per mu, so preventing the occurrence of dead wheat seedlings is particularly important...

Spring management of wheat focuses on fertilizer and water; fertilization and irrigation must keep pace.
Generally carry out compaction and hoeing, and harrowing when the soil surface is frozen. Harrowing or compaction can break up clods, settle the soil, raise and conserve soil moisture, draw on deep water, and promote root growth and tillering. Through compaction, capillaries form in the soil, and deep soil moisture rises along the capillaries to the upper soil layer, which helps nourish root growth. Early-spring hoeing and harrowing...

Spring management of wheat: focus on preventing and controlling the four major harms
How to manage the first spring irrigation and fertilization of wheat? The first spring irrigation and spring fertilization have a great impact on wheat yield. For example: if the wheat is too dense, too sparse, or lodging occurs in the later growth stage, it indicates that the timing of the first spring fertilization and irrigation was problematic. Another example: if the wheat stays green and ripens late, and the grains are shriveled and thin, that indicates your spring water and fertilizer use...

Spring Field Management Measures for Winter Wheat in Northern Xinjiang
Green-up Stage Management: After the beginning of spring (late March to early April), carry out spring harrowing in a timely manner, with a harrowing depth of 5 cm. Harrowing with a smoothing harrow or diagonal harrowing is preferable. Green-up fertilizer should be applied just before or at the early stage of wheat green-up, and it is advisable to apply more to weak seedlings, less or none to strong seedlings, and none to excessively vigorous seedlings. For wheat fields where the total number of stems per mu before winter is less than 400,000 and the wheat seedlings are growing weakly, late...

Timely potassium supplementation for spring wheat is crucial
Since the launch of the spring action for soil testing and formulated fertilization, soil and fertilizer experts from the Chinese Academy of Agricultural Sciences have taken active action, going deep into the fields to guide scientific fertilization. Recently, experts from the Chinese Academy of Agricultural Sciences went to Gaocheng, Hebei, to conduct a follow-up survey of wheat growth. The survey found that due to the low ground temperature this spring, the winter wheat in this area has turned green...

What are the methods for preventing lodging in spring wheat?
"Lodging" is one of the main obstacles affecting wheat yield under conditions of high fertilizer and water. In recent years, the promotion and application of plant growth regulators in wheat production has opened up a new way to prevent lodging and promote increased yield, and is an important supporting technical measure for high and stable wheat yields. 1. Spraying paclobutrazol during the wheat jointing stage...

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...

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 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...

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.
