Second, there is the problem of electricity, even if you have a good water source, water surface. But there must be electricity, because hydroponics must reach a certain density. If the density is too small, it will consume manpower when fishing. If the water surface is too large, it will spread a large area when spreading the feed, which will consume a lot of manpower and waste the feed. When fishing, there are a lot of labor costs and time. If there is a seller waiting for you to catch, the fish in front may have just been caught, but it will take a long time for the fish behind to land, which will take a long time. The mortality rate will increase, or the aerobic time will increase, and the fish will lose their vitality and lose their competitiveness in the market.
If it is surrounded by a hillside, you can consider raising native chickens, planting grass on the hillside, raising native chickens and old geese, raising them yourself, and selling them centrally in Mid-Autumn Festival and Spring Festival. The rest of the time is to raise it behind closed doors. Aquatic plants are planted on the water surface, fish are raised underwater and geese are raised on the water surface. Practice of raising fish and geese.
Third, the climate you mentioned is not so good. I don't know what you mean, but if there is plenty of rain, you should avoid dampness when raising chickens in the ravine. But it's good to raise local chickens in the ravine. There are few places without pollution now, but it seems to be a good place you introduced, and it seems that there is no pollution. If it can be built well, a Little Paradise can be built.
However, we must have market awareness. Any good product also depends on publicity and must be sold in the market to produce benefits. It also needs to reach a certain scale. If it does not reach a certain scale, it will be more difficult to sell, because dealers have to transport it by car. The quantity is not enough, the transportation cost is high, and the dealers don't go, so they can only choose other farmers.
It is generally difficult to grow vegetables in a greenhouse. First, the technical requirements are high. And greenhouse vegetables should be transported in time. There must also be reliable sales channels. Otherwise, the vegetables in the greenhouse will rot in a few days and must be transported and sold in time.
Moreover, the biggest headache in mountainous areas is rain. As long as it rains, it is difficult for cars to get in and out. Whether it is cultivation or planting, if there is a rainstorm, the vegetables and fruits planted can't be shipped out in time. If it is aquaculture, the feed reserve is not enough, and the feed cannot be transported in case of heavy rain. If you want to have enough feed reserves, first of all, the financial pressure is great, and secondly, the preservation conditions should be done well. It is difficult to preserve without a good storage site.
I'm in this business, too. I've been experimenting for years, and I can't stand it anymore.
