What flowers are not suitable for sand?

Sandy soil is not suitable for raising rhododendron, gardenia, dog tooth flower, hibiscus, nightingale, mirabilis jalapa, jasmine, iris, bauhinia, daylily, Ophiopogon japonicus, asparagus, crape myrtle, rose and impatiens.

Sandy soil is suitable for planting dry tropical plants such as Toona sinensis, cactus, aloe, Calligonum mongolicum, lentils, grapes, Salix psammophila, camel thorn, Populus euphratica, Du Ying, Sedum, desert rose, pineapple, or epiphytes such as cymbidium, cymbidium, cattleya, Dendrobium, Oncidium and Phalaenopsis.

Sand, loam and clay are classified according to soil texture.

Fertilization in sandy soil takes effect quickly, crops grow early and develop quickly, but there is no stamina, which often leads to fertilizer deficiency and premature aging, low seed setting rate and incomplete seeds in the later stage. This kind of soil is neither fertile nor resistant to fertilizer. If too much fertilizer is applied at one time, it will not only cause loss and waste, but also cause crops to be crazy for a long time. Therefore, we should pay attention to a small amount of fertilization and apply more organic fertilizer and mud fertilizer.

2. The characteristics of clay are just the opposite of sand. Its texture is sticky, its arable property is poor, and there is a lack of macropores among soil particles, so its ventilation and water permeability are poor. It is neither drought-resistant nor waterlogging-resistant, but it has strong water and fertilizer conservation, is fertilizer-resistant, is not easy to lose nutrients, is richer than sand, decomposes organic matter slowly, and is easy to accumulate humus. This kind of soil is rich in water, less in gas, with little change in ground temperature, cold soil, weak aerobic decomposition, slow decomposition and transformation of nutrients, late effect after fertilization, and the fertilizer has stamina to prevent the seedlings from getting old. Excessive fertilization will cause crops to be greedy and mature late.

3. The loam is between sandy soil and clay, with good fertility. This kind of soil has the advantages of less contradiction between water and gas, ventilation and water permeability, moderate fertilizer supply and conservation ability, drought resistance and waterlogging resistance, strong stress resistance, wide variety adaptability and long suitable farming period, and is easy to cultivate high and stable yield soil. It is suggested that the nutrients needed by crops should be supplemented by soil testing and formula fertilization. What elements are lacking in crops should be supplemented as needed, so as to achieve a balanced supply of various nutrients and meet the needs of crops.
