Love lasts a lifetime

When Li Lin saw the students listening and taking notes so seriously, he continued to talk seriously:"I just talked about how to apply base fertilizer when sowing, and how to apply base fertilizer well. This is the basis for whether corn can grow well.

Of course, when sowing We also need to pay attention to plant spacing and row spacing. What are plant spacing and row spacing?

Does any student know?"

…….

No classmates answered!

"It seems that no one knows that when many farmers plant their fields, they only know how wide the spacing between each cluster should be.

This is an extensive planting method.

We must now focus on scientific planting in order to increase income and production. Therefore, attention should be paid to plant spacing and row spacing.

What is line spacing?

Let me give you an analogy, just like when students stand in line, the distance between one row and the next is called line spacing.

The distance between two classmates on the left and right in a row is called the distance between plants.

Do the students know?" Li Lin asked

"knew! Teacher Li’s metaphor is very vivid."Some students said

"good! Then I will talk about it. According to the requirements, the distance between plants should be between 50 and 60 centimeters, and the distance between rows should be between 60 and 70 centimeters. More reasonable.

This will ensure that the corn is ventilated and has sufficient light.

Are you not singing: 'All things grow by the sun, rain and dew nourish and strengthen the seedlings,……’?

Only with sufficient sunshine can corn grow robustly.

Everyone knows that leaves can produce nutrients through sunlight.

Nowadays, in some places, potatoes are interplanted in corn fields. This is also a new invention and creation.

It can grow both corn and potatoes, achieving a double harvest.

In this way, the distance between corn rows must be at least 120 cm to 1401 cm, so that potatoes can grow well.

Next year I plan to conduct experimental planting on half of our school's land."Li Lin said.

When the students heard what Teacher Li said, they thought it was really a new thing. According to scientific planning, corn and potatoes can be grown in a piece of land. They had never heard of it or seen it before. They were eager to try it. Next year, I will conduct personal experiments under the guidance of Teacher Li.

"Now let me talk about the third question; when corn is growing, it must be hoeed twice on time.

The first time is when the corn seedlings grow to about thirty centimeters high, they need to be hoed in time.

The main task of hoeing this time is to loosen the soil and weed the corn seedlings.

The method is to use a hoe to gently dig up the soil at the roots, but do not damage the roots.

The purpose of this hoeing is to prevent the soil around the corn seedlings from compacting.

Because the roots of the corn seedlings have just begun to grow some tender fibrous roots, these fibrous roots are like human nostrils and need to breathe.

If the soil is compacted, they cannot breathe well, and the corn seedlings will be like a little old man and cannot grow and develop well. Like a child getting sick, the leaves will turn yellow and shrink, or even die.

Another task this time is to note that only two corn seedlings can be kept in each corn nest, and the excess must be pulled out.

Why is this?

I believe the students will understand the purpose of this approach. I leave it to you to think about, without me telling you."After talking about this, Li Lin raised his cup and took a sip of water.

Really:

Li Lin's vivid explanation made the students listen with gusto. The purpose of teaching modern scientific planting methods is to cultivate new talents.
