Under the action of amylase, the starch in the endosperm of growing wheat will be decomposed into sweet maltose, which will promote germination, so the wheat seeds are sweet. Wheat has a wide range of uses, which can be used to make wine, and some farmers will also feed livestock, but eating is the main use, and it is often made into pasta such as bread and steamed bread. In order to make wheat grow normally, in addition to providing 8- 12 hours of light every day, it is also necessary to use chemical seed dressing to control pests.

First, why are wheat seeds sweet?

1, the reason for the sweetness

During the growth of wheat, under the action of amylase, the starch in endosperm will be decomposed into maltose, which provides energy for germination. Starch is not sweet but maltose is sweet, so wheat seeds are sweet. The higher the maltose content of wheat seeds, the sweeter the taste.

2. Introduction to Wheat

(1) Wheat is one of the three major cereals, and China is one of the countries that planted wheat earlier in the world. The main purpose of wheat is to eat, which can be made into bread, steamed bread and other pasta, and can also be used to make wine. Some farmers will also use wheat to feed livestock.

(2) Wheat is a long-day crop, which needs 8- 12 hours of light every day. If the sunshine condition is insufficient, wheat can't pass the light stage, heading and fruiting. Therefore, when planting wheat, sufficient light should be ensured.

(3) During the growth of wheat, if pests and diseases occur, it will easily affect the yield, so it is necessary to prevent pests and diseases in time. Generally, seed dressing is often used to prevent underground pests. For example, in areas with serious take-all disease of wheat, seeds can be treated with 12.5% thiabendazole (take-all net) suspension.

Second, why are the wheat seeds not full?

1, reasons for not being full

(1) Unbalanced nutrition can easily lead to wheat seeds not being full. For example, if chicken manure is applied alone for a long time, it is rich in nitrogen but little in potassium, and long-term application of chicken manure will lead to wheat not being full.

(2) Inadequate wheat seeds may also be caused by diseased pests.

(3) Wheat needs to absorb a lot of water during grain filling, and when the water is too little, the wheat grain will be not full.

2. Skills of handling wheat seeds

(1) seed drying

Before sowing, sowing seeds in sunny and hot weather for 1-2 days can eliminate mildew, sterilize and kill all kinds of pests. Note: seeds should be sown on plastic sheets or soil wheat fields, not on cement threshing ground.

(2) Seed dressing with chemicals

Seed dressing with triadimefon before sowing 15-20 days can inhibit rust, powdery mildew and other diseases, and the dosage is 2g triadimefon /kg wheat seeds, and it can be sealed for 1-2 days after fully stirring with a seed dressing device.
