Rational use of three-wheat feed
Wheat bran, wheat bran and wheat straw are called three-wheat feed, which is an important feed in the main wheat producing areas. Rational use of three-wheat feed can promote the development of animal husbandry. If used improperly, not only can not play the desired effect, but also lead to livestock and poultry infected with some diseases, resulting in economic losses. Wheat bran is a kind of feed with high phosphorus and low calcium, and the ratio of phosphorus to calcium is 4 ∶ 1, which is contrary to the physiological ratio of calcium and phosphorus required by livestock and poultry from 1.5 ∶ 1 to 2 ∶ 1. Excessive feeding of wheat bran can cause calcium deficiency in the proportion of calcium to phosphorus. Such as rickets of young animals and rickets of adult animals.

There are techniques for late sowing wheat to create high yield.
Due to the late sowing time of late sowing wheat (wheat sown after mid-October, generally known as late sowing wheat), it is difficult to achieve complete, strong and uniform seedlings, so it is not easy to obtain high yield. But if properly managed, high production is also possible. The main results are as follows: (1) it takes 10 to 15 days for late sowing wheat with sufficient basic fertilizer from sowing to emergence, which shortens the growth time before winter and weakens the growth time of wheat seedlings in the soil. Late sowing wheat must apply sufficient base fertilizer, 3500 kg of high quality soil fertilizer, 40 kg of ammonium sulfate, 50 kg of superphosphate and 10 kg of potash fertilizer per mu.

Management techniques for late wheat in early spring
Due to heavy rainfall during wheat sowing period around "November" last year, wheat farmers were sown only after cold dew solar term, forming late wheat; in addition, the rainfall at that time also delayed the growth of wheat sown at normal time, also forming late wheat. As a result, more than half of the 1.1 million mu of wheat sown last year in this city are late wheat. The growth characteristics of late wheat are different from those of common wheat, so the early spring management techniques are also different. Late wheat generally refers to wheat sown after the Cold Dew Festival. Its growth characteristics are different from those of wheat sown in suitable time, mainly as follows: overwintering seedlings

Causes and Countermeasures of abnormal Leaf Color of Wheat seedlings
After sowing and emergence of wheat, all kinds of abnormal heterochromatic seedlings are often formed due to the influence of natural conditions and cultivation measures. In order to facilitate seedling and symptomatic management, they are introduced as follows. Causes of yellowing of wheat leaves in yellow leaf seedlings. First, the soil is dry. This kind of situation often occurs in the wheat field where the soil moisture is insufficient or the soil moisture is running away through ventilation. It is characterized by slow birth of tillers, gray-green leaves, short heart leaves, slow growth or stagnation (called by the masses as "shrinking seedlings"), yellow and dry leaves in the middle and lower parts, and few and thin roots.

It is necessary to control rice leaf rollers in time.
Rice leaf curler is one of the main rice pests in our province. It harms rice leaves with larvae, which can make rice leaves withered and white, especially at booting stage or heading stage, which will greatly reduce rice yield. The insect occurs for seven generations a year, and the number of larvae of the second generation in early rice is the most serious. If the control is not timely, it will occur greatly during heading, resulting in inestimable losses. The prediction of rice longitudinal leaf curl should be based on the prediction of occurrence period to determine the suitable period for control. According to the previous situation, it should be at the peak of the moth.

Don't feed fresh wheat chaff to livestock.
As soon as the wheat is harvested, new chaff comes out. However, the newly husked wheat chaff cannot be fed directly to livestock (cattle, horses, donkeys, mules). Otherwise, livestock eat untreated new wheat chaff, mouth is easy to be broken by wheat awn and inflammation. If you want to feed livestock with new wheat bran, you can soak it in 0.3%~0.5% new lime water for 4 hours to make the new wheat bran alkalized and softened, and then feed it after washing it with clean water. In this way, livestock eat easy digestion, can increase calcium to make livestock physique strong; can also let the new wheat chaff stored in the natural strong state for 1 month, in the wheat awn
