Can t rain irrigate the land? Why do farmers water their fields on rainy days?

Today we are talking about watering crops, some crops are sown with enough moist soil, some crops are sown on dry soil, and after sowing they wait for rain, or in fact it does not rain, irrigated land, moist soil before the crops germinate, or even before germination, the crops take a long time to sow seeds, after sowing in places where the soil moisture is insufficient, if it does not rain for a while, <>

The sown seeds have not yet germinated in soil with insufficient moisture. At this time it rains, and it does not rain much, that is, the ground does not permeate. Therefore, the peasants, who were not in a hurry, had to rush to the ground.

Because there is no soggy soil to grind the seeds into powder. That is, the bonsai in the mouth of the farmer should be poured with water as soon as possible and watered on the ground so as not to produce powder. , which is the main reason why farmers have to follow the water closely after the rains.

In order not to lose seeds, when the rain is not enough, farmers should hurry to replenish them. It is said that when it rains one day, and the rain is particularly dirty, and the leaves are discolored by the rainwater, the farmers quickly sprinkle water in the vegetable field once, and the rain is poisonous, so they have to wash it once.

Farmers usually choose to water before 9 a.m. and after 3 p.m. because of the morning or evening irrigation of the land, the noon irrigation of the land and the sun.

If it is too strong, it will cause damage to the roots of the crop, causing the crop to wilt.

Drought hoeing: When there is a drought, it does not rain, so use a hoe.

Hoeing can alleviate the topsoil hoe. The purpose of this is to reduce the evaporation of soil moisture, by hoeing can create a lot of gaps in the surface of the soil, which helps to conserve water, by hoeing to make the roots of plants grow deeper, so that the roots absorb more water and nutrients deep in the soil.

Meiyu Garden: There are a few eggplant tomatoes planted in the yard of the house, and every time it rains, my grandmother asks us to water the vegetable garden with tap water. Because the weather gets hot after the rain, vegetables tend to die in the cold and heat, so especially in a vegetable garden with stagnant water, the rainwater is discharged first, oxygen, and cool tap water.

Effectively increase the oxygen content of water in the soil, while reducing the soil temperature, restore the ability of plant roots to absorb water, effectively resist the hot sun of rain, in addition to vegetables, fruit tree crops can also be watered after rain, restore the water absorption capacity of roots, and improve growth momentum.

Rainwater can irrigate the land, but because some crops require more water, farmers usually go to specific crop fields to release water to make them grow better.

If irrigation is not carried out, the land will return to alkali, and the water content in the soil will be too high, and the plants will die.

First of all, rainwater is the most primitive irrigation method, as long as your crops are exposed, he will irrigate directly. Some crops are dry, so they need rain to water them.

Because the farmer observed that the rain was not very heavy, but only a drizzle, which had little effect on watering, and the soil needed enough moisture to supply the vegetables to grow, the farmer would continue to water the land.

Because the amount of rain is not enough to allow crops to grow healthily, farmers also water their fields.

In many cases, the rainfall is small and cannot penetrate into the soil, and the roots of crops cannot absorb water, so it is still necessary to water the ground; Sometimes it is watered after fertilization, and the field that has only rained cannot dilute the fertilizer, so it is necessary to water, otherwise it will burn the crops.
