Nutritional needs of melon

The rotation regime is suitable for melon, after the melon crop to the rice crop or vegetable crop. Do not grow melon continuously many consecutive crops on the foot of the field.

For sweet, aromatic melon and yield, it is necessary to add fertilizer containing many medium and micro-nutrients

Pear melon is a short-term fruit and vegetables of high economic value, suitable for light, bare sandy soil, good drainage, suitable pH from 5.5 to 6.5, porous, humus content> 2%, temperature suitable for pickles growing from 24 - 35 degrees C.

The rotation regime is suitable for melon, after the melon crop to the rice crop or vegetable crop. Do not grow melon continuously many consecutive crops on the foot of the field.

Investigation of intensive melon in the Red River Delta provinces such as Hai Duong, Bac Ninh, Hanoi, Vinh Phuc, Thai Binh ... shows that the biggest limitation in melon cultivation is sweetness, low aroma, energy Unstable productivity, poor pest resistance, abuse of plant protection drugs.

Causes due to unreasonable fertilizer use. Farmers in the melon growing regions know about the soil, fertilizer, nutritional needs of the cucumber is limited, often using the single fertilizer that nitrogen fertilizer is said to be the main fertilizer.

In many places, people have used some types of NPK mixed fertilizers, but most of them are common types of NPK that belong to the low-nutrient fertilizer group (there are 3 or 4 nutritional elements).

How to use leaning back to nitrogen, lack of almost completely medium nutrients, micronutrients are essential nutrients for melon.

According to scientific research results, to get 15 tons of quality fruits / ha, melon plants take away from fertilizer through the soil about 112 kgN, 45 kg P205, 97 kg K20, 300 kg CaO, 45 kg MgO, 100 kgSiO2, 4kgS, 180 g Zn, 50 gB, 4gFe.

So what are the nutritional factors that play a role in growth and development, yield, sweetness, aroma of pear melon?

Protein (N): Protein helps to sprout tops, branches, leaves, grow stems length, nitrogen helps plants grow to synthesize fruit formation, nutrient accumulation in fruits, excess nitrogen, soft body, thin leaves, dark green, dull green, poor photosynthesis, poor pest resistance, small fruit, sweetness reduced, less.

Lan (P): Lan promotes rapid growth and many root systems of melon, seedling, top and post fruit. Lan also participates in the process of dividing flower sprouts, stamens, and stamens to facilitate the fruiting process.

Enough phosphorus melon grows well, lacks unicorn roots and stunted plants, plants absorb nutrients from poor soil, slow-growing plants and poor fruit pollination.

Potassium (K): Potassium promotes nitrogen assimilation in plants, potassium promotes the transport of nutrients from leaves to fruits, participates in the process of sugar accumulation in fruit, helps to make the firm process cells, hard melon plants, increased resistance to pests and diseases.

Sufficient potassium color fruit beautiful, sweet sugar in high fruit. Lack of potassium, soft plants, poor resistance, reduced sweetness.

Calcium (lime): Calcium participates in the process of decontamination of organic manure, decomposing plant material in the process of decomposing to create acidic detoxification due to the application of sour fertilizers, adjusting the pH to 5.5 for plants melon growing.

If lack of calcium leaves melon slow growth or curly leaf edges, young root systems are less developed, affecting the nutrient absorption of the plant.

Magnesium (MgO): Special cucumber needs a lot of energy from sunlight. Magnesium helps to improve photosynthetic performance, adjust leaf color, increase leaf thickness, increase chlorophyll.

Provide enough magnesium, increased photosynthesis leaves, overcome the lack of light in the murky weather, especially the spring-summer melon.

Magnesium helps synthesize sugars accumulated in fruits when ripe, making sweetness increase, lack of magnesium photosynthesis, dull evergreen leaves, greatly affecting productivity.

Silicon (SiO2): Has a special role in the formation of chalk, bristles on stalks, shoots and leaves of melon leaves.

Silica thickens the cuticle under the leaf surface, which helps plants reduce water evaporation to prevent drought better, resist pests, diseases on leaves, and protect fruit pods to limit bollworms.

Micronutrients include zinc (Zn), Bo (B) and iron (Fe): Mainly involved to form enzymes in plant cells, helping to make vitamins and aromas in fruits.

Providing sufficient micronutrients, the melon fruit has a characteristic aromatic flavor, extending the preservation time, improving product value. However, the actual production does not provide all 13 nutrients for melon.
