How to Fertilize on Sand Land
Sandy sand has high sand content, good permeability, rapid soil temperature change, low nutrient content, and poor fertilizer retention. Therefore, when applying fertilizers, it is necessary to have a reasonable method of fertilization so as to prevent premature aging of the crop due to lack of fertilizer. When applying fertilizers, the following points should be noted:
First, the low content of organic matter in sandy soil should be increased by organic fertilizers to increase the content of organic matter in the soil.
Secondly, it is advisable to use cold manure such as cow dung or semi-ripe organic manure as base fertilizer in order to increase the soil's ability to conserve fertilizer and water;
Third, top-dressing grasps the principle of “a small number of times†to reduce nutrient losses and improve fertilizer utilization;
Fourth, in the later stage of crop growth, it is necessary to add nitrogen fertilizer in time to prevent production loss due to premature aging of crops.
Ginseng can improve the general condition of diabetic patients, but does not change the degree of hyperglycemia. In other words, ginseng can reduce urinary sugar and blood sugar in patients with mild diabetes mellitus by 40-50 mg, which can be maintained for more than two weeks after discontinuation of medication. Although the effect of reducing blood sugar in moderate diabetes mellitus patients is not obvious, most of the general conditions have improved, such as thirst disappeared or alleviated; some patients can reduce insulin consumption after taking ginseng.
