Chapter 439 (2/2)

After filling out the registration application and sending an email, Fang Ye explained: ”because our zoo produces a lot of feces every day!

When the elephant Pavilion is repaired and the elephant comes, an elephant can row dozens of kilograms of feces a day.

It's a pity that so much excrement can be directly removed and disposed of. It can be used for composting and farming, planting healthy and environmentally friendly vegetables and fruits for animals and tourists. It not only saves money, but also conveys the concept of resource recycling and sustainable development.

In the small experimental field opened up in the zoo, let the children participate in planting to understand how the crops in the field grow and what kind of environment-friendly ecological agriculture is. ”

”Wow, this is one arrow and three eagles!”

“66666”

”If there were such a zoo near my home when I was a child, I might be a biologist now.”

”This is great! We can cultivate children's idea of not wasting food. ”

”I used to work in a compound fertilizer farm and was very interested in planting technology. I often consulted vegetable farmers.

I'm still impressed by the key points of medicine and fertilization taught by my tutor.

For lettuce and cabbage that can be harvested in a month, compound fertilizer shall be applied once in 3 days and pesticides for pest control shall be applied once in 7 days

The land I see is basically in a state of serious hardening.

If you don't plant vegetables like this, you won't grow fast. The more you plant vegetables like this, the more hardened the soil is. This is a vicious circle.

In addition, rice needs 7-9 times of pesticide and 2-4 times of chemical fertilizer in the four month growth cycle. In order to produce more yield, more than 100 kg of chemical fertilizer can be sprinkled on one mu of land.

With so many chemical fertilizers and pesticides scattered into the field, can the vegetables and rice planted be good for your health?

For a long time, it will also cause great pollution to the soil and water sources. ”

”The name of a big man is a farmer.”

Jiejia returns to the field: ”I'm really farming myself. Although the output is less, it's safe to eat what you grow. ”

He is very interested in farming and has great ideals!

After accumulating some wealth, he got an organic farm.

Through a lot of hardships, we can grow high-quality rice and good dishes.

But without publicity, there is no market, and other consumers don't recognize it. What's good about you? Why is it so expensive?

For most people, eating is not eating.

Without fertilizers and pesticides, the output is small! If you don't sell it, you can't earn it back.

Organic farms lose money every year and are now closed down.

Although he didn't make much money, he was self-sufficient, and his ideal was half realized.

Hearing about ecological agriculture, I couldn't help sighing.

Fang ye said: ”pesticides and fertilizers not only have an impact on the land...”

Chatting with netizens, he unknowingly came to the animal hospital.
