The hill not far from the side of the zoo office building is covered with a green and lush grove.


    At the foot of the mountain, a bluestone road surrounded by purple morning glory and yellow chrysanthemums on both sides twists and turns and disappears in the mountain. Green trees and shrubs are hidden. A building in the style of brown and yellow logs stands on the hillside, giving people a feeling of being away from the noise.


    The fragrant breeze spreads the fragrance of flowers. The sun is warm and comfortable, and everything looks so quiet and beautiful.


    In the side yard of the villa, Fang Ye stood next to a large wooden box with a side length of one square meter, picked up a sack next to him, and poured the dead branches and leaves into it.


    Now he''s doing composting!


    In short, it is to decompose organic matter into fertile humus, which is rich in organic matter, nutrients and microorganisms.


    Composting doesn''t work overnight. It''s a little late to prepare for farming and then stacking. He plans to use it when it''s ripe in spring.


    Although there is spiritual earth, the number of spiritual earth is too small to use all spiritual earth.


    Moreover, in his plan, a field animal exhibition area will be built behind the zoo. Now the process of farming is also a process of learning and thinking. I can personally understand what changes will occur in the process of farming, so that it will be more convenient to design the field exhibition area in the future.


    The farming that fangye plans to carry out is not a conventional planting method, but a more healthy and environmental friendly agricultural method, which can be called organic agriculture, ecological agriculture and Pumen agriculture!


    Do not use chemical fertilizer, herbicide, insecticide or plastic film in greenhouse.


    If the conventional planting method is to feed crops, organic agriculture is to feed the soil.


    There is also a very complex ecological environment in the soil, which provides a good living environment for various beneficial organisms in the soil, including bacteria, fungi, protozoa and nematodes. These organisms will establish a mutually beneficial relationship with plants.


    Microorganisms can not only provide nutrients to plants, but also improve the ability of plants to prevent diseases and pests.


    Good soil can also attract beneficial insects, such as earthworms and arthropods, to settle down in the vegetable garden, and the organic matter they digest and decompose is used as nutrients and food for microorganisms.


    Earthworms and arthropods are the food that birds eat from protein sources, which can attract them to the vegetable garden. Although birds may eat a small part of crops, they can also eat pests. Generally speaking, the benefits outweigh the disadvantages!


    When we focus on feeding the soil in the garden rather than the plants, over time, we will build a complete ecosystem to help the plants grow healthily and become more nutritious.


    The soil planted in this way has better permeability, can save water, and the plants are stronger in dry weather.


    Do not use pesticides or pesticides. The vegetables planted are safe and healthy. They can be eaten directly without washing.


    In fact, there are many details in the implementation process. For example, covering the soil with straw, fallen leaves and newspapers can not only moisturize the soil, reduce the number of watering, but also reduce the growth of weeds. After the straw newspaper rots, it can also be used by microorganisms in the soil.


    When different crops are used for land rotation, different crops have different root lengths and absorb different nutrients. Crop rotation can be conducive to the permeability of soil and the reuse of nutrients, so that the land has the opportunity to cultivate and nourish.


    Moreover, crops such as tomatoes and potatoes are very sensitive to pathogens. If they have been planted on the same land, they are easy to get sick. They can reduce the possibility of pathogens through rotation.


    Fang Ye poured the branches and fallen leaves into the big wooden box, and then poured in a bag of kitchen waste, what egg shells, chopped banana peel and coffee grounds, which were all obtained from the canteen.


    Blue carp moved a small bench and sat not far away, holding a variegated flower cat in her arms. Today she is on holiday.


    The cat was lying in her arms, her tail gently sweeping around her smooth arm, so comfortable that she narrowed her eyes and made a "snoring" sound.


    It''s the one Fang Ye fed in the dormitory.


    Usually I can''t trace in the zoo. Today I came to the villa.


    The blue carp teased the cat and couldn''t help asking, "principal, why don''t we adopt it!"


    Fang ye said with a smile, "yes, add a little vitality to the house. But if you want to adopt it, you have to cut an egg. "


    The vaccine has been caught and beaten once, otherwise it can''t run around. Stray cats are at risk of spreading cat plague.


    The stray cats that can be seen in the zoo are basically bred and sterilized. Fang ye also saw that there are no other stray cats in the zoo, so he put his eggs and didn''t cut them, otherwise there are many stray cats, which is very troublesome.


    Although cats and cats are cute, they can not only catch mice, but also catch birds and dig out their nests.


    Hunting is not just for food. When you are full, you have more strength to catch and play.


    A few stray cats are acceptable, but more will certainly affect the number of birds in the zoo.


    The flower cat in the blue carp''s arms suddenly felt a chill in his lower body, subconsciously clamped the eggs and raised his head vigilantly.


    After Fang Ye threw the kitchen waste into the big wooden box, he took a wooden stick and turned it over, and poured in some smashed useless waste documents. Then he picked up a sack and poured in a pile of animal feces, which can be easily made in the zoo.


    The blue carp asked curiously, "principal, can paper also be composted?"


    "Of course! Clothes can be composted. Just tear them up. It''s a bit like a witch''s crucible. All kinds of strange things can be thrown in. "


    Although the feces gave off a pungent smell, it did not affect Fang Ye''s interest.


    While stirring, he said: "composting needs green and brown raw materials. Green raw materials such as plant stems provide nitrogen and high humidity, while brown materials such as leaves provide carbon and little water.


    This way of putting a little of all raw materials is the best. If only one or two raw materials are used, composting may lack a certain nutrition, and diversified raw materials can ensure more abundant trace nutrients and achieve natural balance.


    These are the feces of ring tailed lemurs and macaques. They are pulled down by eating fruits and vegetables. They must be nutritious.


    The size of the composting box is also exquisite. If the side length is too small or too narrow, the temperature generated in the composting process cannot be guaranteed. The temperature generated by the large fertilizer pile is beneficial to the microbial activities inside, so as to speed up the decomposition process of organic matter. "


    "How long will it take?"


    "Half a year. This method composts slowly, but it''s very convenient."


    After pouring in the material, fangye covered it with a layer of cardboard to reduce the infiltration of rainwater in rainy days and prevent the composting from getting too wet.


    Then he took off his shoes, climbed onto the compost box, jumped up and compacted it.
