Fertilizing melon vegetables is the key to increasing yields of melons. The practical experience of vegetable farmers is to look at the land and see how to fertilize vegetables.
"Farming" means that if there is no fertilization on the rainy day, the fertilizer will not be lost. The days of nausea will not be applied, the fog will not be applied, and the temperature will not be applied, so as to avoid the occurrence of mildew in the plants. Fertilization should be selected in sunny weather. "See fertilization", that is, good soil quality Less application, poor soil quality and multiple application, over-consolidation, hard-to-preserve application of organic fertilizer and other topdressing concentrations should be appropriate, diligence, thin pouring, multiple times, a small amount.The general application concentration of the seedlings is 10 %-15% of the excrement water can gradually increase as the plant grows, and can be increased to 30% to 40% in the later stage of growth.
When cooking vegetables, it is necessary to know how to identify which fertilizer is lacking in vegetables. Also learn to "six look":
Types of fertilization: legumes have nitrogen-fixing rhizobium, require less nitrogen and require more phosphate; root vegetables and yams need more potassium; leafy vegetables only need more nitrogen; fruits and vegetables in the application of nitrogen fertilizer basis On the other hand, phosphorus and potassium fertilizers are needed.
Soil fertilization: different soil quality, fertilization methods are not the same. The light loam soil pellet structure has good fertilizer and fertilizer performance, and can be applied and reused. The sandy loam was used less frequently to prevent fertilizer waste. At present, many vegetable farmers neglect farmyard manure and phosphorus and potash fertilizers, leading to imbalances in the nutritional ratio of vegetables and should be improved in time.
It is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs. Its aim is often to find a source of a disease or to exclude pathology. The practice of examining pregnant women using ultrasound is called obstetric ultrasound, and was an early development and application of clinical ultrasonography.
Ultrasound are sound waves with frequencies which are higher than those audible to humans (>20,000 Hz). Ultrasonic images, also known as sonograms, are made by sending pulses of ultrasound into tissue using a probe. The ultrasound pulses echo off tissues with different reflection properties and are recorded and displayed as an image.
