What are the latest measures for frost protection of wheat in early spring?
Hooeing: When the soil is thawing and releasing moisture, hoeing the surface while it is still frozen can loosen the soil, preserve moisture, raise the temperature, and control weeds, enhancing the wheat seedlings' ability to withstand the cold. Regardless of whether the seedlings are weak, overly vigorous, or strong, hoeing should be done promptly during the green-up stage; for fields with a tendency toward excessive growth, deeper hoeing can be done as appropriate to suppress spring tillering. When hoeing, be careful to hoe shallowly and finely, and push apart clods as you go; if the soil is first pressed before hoeing, the soil will not be hollow, thus achieving the effect of loose on top and firm below, drawing up moisture and preserving it.

Production Technology for Drought Resistance and Early Maturity Promotion of Soybean During the Summer Hoeing Period
1. Symptoms: When infected at the seedling stage, the stem base turns brown and becomes water-soaked; under high humidity, cottony white mycelium grows; later the diseased part shrivels, turns yellow-brown and dies, and the seedlings lodge and die. Symptoms at the adult plant stage: Infection at the adult plant stage mainly affects the soybean (4458,-23.00,-0.51%) stem, and the upper leaves of plants in the field turn brown and die. Pods...
