Can rain water the land after the solar terms?

Watering wheat before sowing is rarely done; As for watering after sowing, it is also done less. It is the time when winter wheat is sown, which is the most frequent solar term in a year. Although it is mostly intermittent light rain, it is very helpful for soil wetting and seed emergence before and after wheat sowing.

1、? In fact, it is not advisable to water the open space before sowing wheat. In the past, when wheat was planted in Gansu rural hometown, this land needed to be plowed in advance. Now use a rotary cultivator to cultivate. As we all know, the land cultivated by rotary cultivators is very soft and very suitable for sowing winter wheat.

If you water and irrigate in advance in this case, it will inevitably cause soft soil damage, even slight hardening, which is not conducive to the sowing of winter wheat, so I suggest not to water and irrigate soft soil before sowing wheat.

2、?

Wheat should not be watered for a short time after sowing. In particular, it is necessary to water wheat before it overwinters. Note that the time point is in the "light snow" solar term, so most of the winter wheat is planted between the "cold dew" and "first frost" solar terms, 30 to 45 days apart from the "light snow" solar term. So at this time, the winter wheat has been completely rooted and the soil is relatively solid.

Therefore, the average daily temperature at this time will not exceed 10℃, so it is necessary to water the winter wheat for the first time. This time is also longer after sowing winter wheat. There is a good saying: "winter irrigation is not winter irrigation, the quality is halved", which shows the importance of winter irrigation.

Then water it again the next spring. It is best to water in February and March. Before watering, you must look at the humidity of the soil, that is, the overall humidity, before deciding how much to water. So most of the winter wheat is planted on a large scale in Henan and Shandong in the North China Plain and the Central Plains Plain, so it is very important to water the winter wheat twice.

Therefore, it is concluded that it is not advisable to water wheat before sowing, which will destroy the softness and permeability of soil. Too much water will cause slight soil hardening, which is not conducive to winter wheat sowing. Then, if the winter wheat is watered once after 40 days of sowing, at this time, the wheat has completely taken root, and there will be cold and drought in winter, so the winter wheat planted in large areas in the plain must be watered. There is also entering the green water in February-March next year. The specific watering amount depends on the water content of wheat growth.
