When is it good for wheat to be short and sturdy? How do you play?

The growth stages of wheat are different in different places at the same time due to different climates. The wheat in some areas is now in the jointing stage (such as Jiangsu and other places), some areas are in the booting stage (Henan and other places), and some areas are just in the green stage. Therefore, the management measures of wheat are also different in different regions at the same time. When is it good for wheat to be short and strong? How do you play?

Daizhuangsu is an antagonist of gibberellin. Spraying Daizhuangsu on prosperous wheat in spring can inhibit gibberellin biosynthesis, control vegetative growth, promote reproductive growth, promote short and strong wheat seedlings, stout stems, thick green leaves, well-developed roots, improve stress resistance, and the dosage is reasonably determined according to the degree of wheat growth. When will the wheat be short and sturdy? The following article describes in detail the time for the use of dwarf in wheat.

When will wheat be short and strong?

The best spraying time should be in the early stage of wheat jointing (after the winter wheat turns green). The earlier the application time is, the worse the dwarfing effect is, but the better the yield increasing effect is; the later the application time is, the more obvious the dwarfing effect is, but the greater the effect on yield is. The later the yield is, the greater the yield reduction is.

The jointing stage of wheat refers to the hard nodes that can be touched by hand at the base of wheat, when the leaves on the base of wheat leave the surface and begin to change from clustered leaves to erect leaves, rather than what farmers call jointing and heading stage. It would be very serious to reduce production by using chloramphenicol at this time.

The method of using Dwarf Sodium in Wheat sowing period

The main results are as follows: 1. Seed dressing with growth retarder can increase the emergence rate, widen and thicken the leaves of wheat seedlings, increase the occurrence of tillers, increase the number of tillers, increase secondary roots, short and strong seedlings, thick green leaves, and improve the ability of cold and drought resistance.

2. Soaking seeds with 50% Aizhuangsu water agent 16-33 times solution for 6-12 hours and sowing after drying in the shade can make the root system developed, the leaf color thick green, promote the increase of tiller, the wheat seedling is strong, and the effect on late sowing wheat is more obvious, which is beneficial to improve the cold resistance.

3. Soaking the seeds with 2500-5000mg/L solution, or dressing the seeds with 10 grams per kilogram of wheat seeds, drying and sowing, the seedlings grow healthily, the root system grows well, the effective tillers increase, the stems are sturdy, the basal internodes are shortened, and the lodging resistance is improved. If 3000mg/L solution is sprayed at the jointing stage of wheat, wheat lodging can be prevented.
