How to make good use of the terrain to grow crops? How?

There are different types of agriculture on different terrains. The mountainous terrain is high, which is suitable for developing forestry, fruit industry or animal husbandry. Flat terrain, suitable for the development of agricultural management; Qinghai-Tibet Plateau is an open plateau. Animal husbandry has been developed in arid and semi-arid areas, and planting can be appropriately developed in areas rich in water resources.

1. Sandy soil is suitable for planting lentils, cauliflower, lettuce, Toona sinensis, sandy onion, eggplant, potato, leek, taro, water chestnut, garlic, coriander, carrot, ginger and other vegetables. Sandy soil is very loose, with good air permeability and water permeability, but its ability of retaining fertilizer and water is poor.

2. Clay can grow deep-rooted flowers such as lotus, lotus, bauhinia and osmanthus. Clay is superior to other soils in terms of fertilizer and water conservation, with rich nutrition, but poor air permeability, so it needs deep ploughing before sowing.

3. Red soil field is suitable for planting sorghum, wheat, peanuts, corn, tea, citrus, red persimmon, Chinese fir, tung tree, bamboo, palm and other crops. The organic content of red soil is low, so the organic content and nitrogen fertility of red soil should be improved when planting crops.

4. Black soil is suitable for planting wheat, cotton, corn, sorghum, rice, sugarcane, eggplant, licorice, ginseng, astragalus, acanthopanax senticosus and other plants. Black soil is a kind of soil with good properties and high fertility, which is very suitable for plant growth, with high survival rate and high yield.

Watermelon is very suitable for growing in sandy land. Watermelon is very popular in summer because of its high sugar content. Its seedling raising time is from April to July and August, which is short, and it can also be intercropped with other crops to improve agricultural production efficiency. For sandy soil, due to its low specific heat capacity, the temperature difference between soil and daytime is the largest when the temperature drops at night. The advantage of this soil is that it can reduce the respiration of plants such as watermelon at night as much as possible.

6. What is to be said below is that the ability of storing water and fertilizing in sandy land is weak, so if the crops planted are not drought-tolerant, it will inevitably lead to the rapid withering of crops and the natural growth will not be very good. Therefore, it is suggested to consider some drought-tolerant crop varieties, such as wheat and corn, which have narrow leaves and strong drought resistance. In addition, soybeans and sesame seeds can also be used. Because of the high leaf density in the late growth stage, the soil water loss rate of this kind of crops is low. Of course, when planting, we should choose some drought-tolerant varieties. It is worth mentioning that for sandy land, try not to grow vegetables. Generally speaking, vegetables have a high demand for water and fertilizer, so after planting vegetables, symptoms of precocity usually appear. Choose drought-tolerant crops, or plant some substances with high sugar content such as watermelon and pumpkin with high economic benefits. For areas regarded as inferior areas such as sandy land, we can also obtain good economic benefits according to local conditions.
