What kind of environmental conditions does the growth of wheat need?

1, the soil layer is deep, the structure is good, and the tillage layer is deep, which is beneficial to water storage and fertilizer conservation and promotes root development. Soil structure refers to the proportion of solid, liquid and gas, which is closely related to soil moisture, air, temperature and nutrients.

2. The average daily temperature during the adaptation period of winter varieties is 16 ~ 18℃, that of semi-winter varieties is 14 ~ 16℃, and that of elasticity is 12 ~ 14℃. Temperature and air are affected by geographical latitude and altitude, that is, the higher latitude and altitude, the lower temperature and the earlier sowing date. ?

3, wheat long-day crops (8 to 12 hours of light every day), if the sunshine conditions are insufficient. Can't pass the light stage, can't knot, can't bear fruit. The photoperiod of wheat is after vernalization.

Storage method

1, the hot warehouse is tightly protected. In sunny and hot weather in midsummer, the wheat temperature will be exposed to about 50oC for more than two hours, and the moisture content will drop below 12.5%. When it is hot, put it into the warehouse, and the whole warehouse is sealed, so that the grain temperature is above 40oC for about 10 days.

2. Cryopreservation: When the temperature is low in winter, it is necessary to turn over the warehouse, remove impurities and freeze to reduce the Maï Wenn to 0oC, and then seal it while it is hot, which has a good effect on eliminating overwintering pests in wheat piles. However, for the low temperature and closed wheat pile, it is necessary to prevent contact with warm current and avoid condensation on the surface of the wheat pile.

3. Natural hypoxia, when wheat is harvested, it is at high temperature. If the precipitation falls below 12.5% in time, the characteristics of high grain temperature and vigorous physiological activity in the post-ripening stage can be used to seal the film, so as to achieve the natural hypoxia state of the wheat pile, thus inhibiting the harm of pests.
