What is micro fertilizer? Do I need to grow watermelon?

Fertilizers that provide plant trace elements are called microfertilizers. In order to increase production and income, artificial cultivation of watermelons requires additional micro-fertilizer.

Compared with a large number of elements such as carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, the remaining 7 elements that require less and contain the following are called trace elements. Micro-fertilizer mainly includes iron, zinc, copper, manganese, boron, molybdenum and several elements.

Commonly used micro-fertilizer application methods:

1. Molybdenum fertilizer: ammonium molybdate is commonly used, which can be used as base fertilizer, seed fertilizer and top dressing. The soaking concentration was 12 hours, and the topdressing concentration outside the roots was the best spraying effect at the seedling stage and vine extraction stage.

2. Zinc fertilizer: mainly zinc sulfate, which can be used as base fertilizer, seed fertilizer and top dressing, and every 667 square meters (1 mu) with kilograms of zinc sulfate, sprinkled as base fertilizer. However, it cannot be mixed with phosphate fertilizer.

Solution soaking can be used, seed dressing (1 g of zinc sulphate per kilogram of seeds) or foliar top dressing with zinc sulphate.

3. Copper fertilizer: copper sulfate is commonly used. It can be used as base fertilizer, with a dosage of kilograms per 667 square meters (1 mu), the available solution soaks the seeds, and the solution can also be used for root topdressing.

4. Boron fertilizer: borax, boric acid, boron magnesium fertilizer, boron-containing superphosphate, etc., of which boron-magnesium fertilizer and calcium borate are mainly used as base fertilizer, and the dosage per 667 square meters (1 mu) is 20-30 kg and 40-50 kg respectively.

Abbreviation for micronutrient fertilizer.

Micro fertilizer is a fertilizer that provides trace elements to plants, such as copper fertilizer, boron fertilizer, molybdenum fertilizer, manganese fertilizer, iron fertilizer and zinc fertilizer, etc. They are mainly some inorganic salts and oxides. Most of them are by-products or waste materials from mining and metallurgy.

It can be used to formulate multi-fruit foliar fertilizers, vegetable foliar fertilizers and compound fertilizers.

The fertilizer used to grow watermelons is basal fertilizer, and before planting, mixed with rotted farmhouse fertilizer in the soil can accelerate germination. During the seedling growth period, fast-acting fertilizer can be applied to the soil, which can accelerate the growth of seedlings. When the watermelon vine grows, urea, calcium fertilizer, etc. need to be applied, and farmhouse fertilizer and compound fertilizer can be applied during the fruit period, which can make the watermelon have sufficient sugar and good taste.

1. Base fertilizer

Watermelon is sweet, juicy and refreshing, and is a common fruit in summer. The germination and growth of watermelon are inseparable from the irrigation of fertilizer, but many people do not know what fertilizer to use to plant watermelon, planting watermelon first needs base fertilizer, mixing rotten farmhouse fertilizer in the soil can effectively promote the growth of watermelon.

2. Promote seedling fertilizer

Seedling fertilizer is the fertilizer applied when the seedlings grow 4 or 5 leaves after watermelon transplanting, and double enhancers can be applied at this time, which can effectively accelerate the growth of seedlings, so that the watermelon has a high sugar value and sufficient water. A small amount of fast-acting fertilizer can also be applied, which can also effectively accelerate the growth of seedlings.

3. Promote vine fertilizer

After the seedlings grow 40 cm, urea, calcium and potassium fertilizers can be applied to the soil, which can effectively promote the rapid growth of seedlings for climbing vines, accelerate leaf growth, accumulate nutrients, and accumulate energy for flowering and fruiting.

4. Puffed melon fertilizer

During the flowering and fruiting period of watermelon, puffed melon fertilizer can be applied, which can make the watermelon large and full, with high sweetness and rich juice. At this time, you can apply compound fertilizer based on farmhouse fertilizer, which contains more organic matter, which can promote the rapid growth of watermelon and increase the yield of watermelon field.

If you use base fertilizer for planting watermelon, it is best to use high nitrogen and high potassium fertilizer, and the later application of high potassium fertilizer can improve fruit quality. However, the best is farmhouse fertilizer, which is healthy and pollution-free.

Special fertilizer for watermelon. It is a chemical fertilizer that is specially applied to the production of watermelon. It is mainly made of the proportion of nitrogen, phosphorus and potassium required for the growth and development of watermelon, and other trace elements.

It is different from general micro-fertilizer, the application rate is larger, and it is mainly used to replace the use of general chemical fertilizer on watermelon.

<> watermelon (scientific name: Citrullus lanatus (thunb.).) matsum.

et nakai) annual vine; The stems and branches are stout and have distinct ridges. tendrils stout, pubescent, petioles thick, pubescent; The leaves are papery, triangular in outline, with whitish-green bouts, with two masks with short stiff hairs, and the base of the leaves is heart-shaped. Monoecious.

Both female and male flowers are solitary in leaf axils. Male pedicels 3-4 cm long, densely pubescent with yellowish-brown flowers; calyx tube broadly bell-shaped; corolla pale yellow; The stamens are nearly detached, the filaments are short, and the chamber is curved. Female flowers:

calyx and corolla identical to male flowers; The ovary is ovate, stigma kidney-shaped. The fruit is large, nearly spherical or oval, fleshy, juicy, smooth skin, and varied in color and ornamentation.

The seeds are numerous, ovate, black, red, smooth on both sides, obtuse at the base, usually slightly arched at the edges, flowering and fruiting in summer.

It is cultivated all over China, and there are many varieties, exocarp, pulp and seeds in various forms, and the most famous ones are Xinjiang, Lanzhou, Gansu, Dezhou, Shandong, Dongtai, Jiangsu and other places. Its original species may come from Africa, and has been widely cultivated in the tropical to temperate zones of the world for a long time, and was introduced to China in the Jin and Yuan dynasties.

Watermelon is a summer fruit, the flesh is sweet, can cool down the heat; The seeds contain oil and can be used as recreational food; The peel is medicinal, and has the effect of clearing heat, diuresis and lowering blood pressure.

It is best to apply basal fertilizer to watermelon.

Watermelon likes fertilizer, the demand for fertilizer is greater, mainly organic fertilizer, appropriate application of nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, nitrogen, phosphorus and potassium three elements combined application, but also an appropriate amount of supplemental trace elements, so as to meet its growth needs. Planting watermelon needs to apply sufficient base fertilizer, which is the key to increasing yield, and can use well-rotted chicken, duck, pig, cow, and other manure, or you can buy organic fertilizer and cake fertilizer.

Flush fertilization or dilute manure water is applied at the seedling stage, liquid fertilizer, manure, urea, superphosphate and potassium sulfate are applied when the vine is started, and special fertilizer or superphosphate, urea and potassium sulfate are applied at the fruit expansion stage. These fertilizers are rich in organic matter and nutrients, which are conducive to improving soil fertility and soil structure, and promoting the growth and development of watermelon.

Basal fertilizer application method

Watermelon basal fertilizer is mainly to meet the large nutrient needs of the rapid growth of melon seedlings in the early stage, so as to ensure the early vine growth, flower bud differentiation and seedling strengthening, the types of fertilizer required in this period include both nitrogen, phosphorus and potassium macroelements, and calcium, boron and zinc and other medium and trace elements, but also sufficient organic matter to supplement; Insufficient or incomplete application of basal fertilizer will cause many problems such as sluggish growth of melon seedlings, weak yellow growth, small amount of flowering and fruit set, and easy defertilization in the later stage, which will directly affect the yield and quality of watermelon.

Therefore, when applying basal fertilizer to watermelon, it can be in accordance with sufficient decomposed farmhouse fertilizer or organic fertilizer + scientific ratio of nitrogen, phosphorus and potassium compound fertilizer + various medium and trace element fertilizers. Root topdressing is mainly adjusted according to the fertilizer requirements of five different growth periods: watermelon extension stage, gourd expansion stage, coloring stage, rejuvenation period and yield guarantee period.

According to the different growth stages of watermelon, basal fertilizer, seedling fertilizer, vine fertilizer and gourd fertilizer should be applied.

1. Base fertilizerWhen cultivating watermelons, apply base fertilizer and mix it directly into the soil.

2. Promote seedling fertilizer

Seedling fertilizer is applied after the watermelon is planted, specifically when four or five leaves have grown.

3. Promote vine fertilizer

When the watermelon begins to be drawn, it is necessary to apply vine-promoting fertilizer, specifically urea fertilizer, potassium fertilizer and calcium fertilizer when it grows to 40 cm long.

4. Puffed melon fertilizer

When the watermelon blooms and bears fruit, it is necessary to apply puffed melon fertilizer, and the fertilizer applied at this time is mainly compound fertilizer and farmhouse fertilizer.

Watermelon breeding techniques and methods:

1. Establishment of seedbed.

The seedbed must be located downwind, in the sun, in an area with high terrain and close to water resources. The width of the seedbed is meters, the depth of the meter, and the length is determined according to the demand. When creating the seedbed, care should be taken to make the bottom as flat as possible.

2. Preparation of nutrient soil.

Each cubic soil layer (preferably the plot that has not been planted for many years) is mixed with cubic organic fertilizer and 3 6 grass ash, and the cup seedlings are raised after the culture soil is adjusted.

3. Seed treatment.

Take 55 to 60 minutes of warm boiled water, put the seeds in and mix for 15 minutes. After blanching, remove the seeds, soak them in cold water for 4 to 6 hours, then rinse the seeds and rub the water mucilage on the surface of the seeds.

Fertilizer needed to plant watermelon: lightly apply seedling fertilizer, skillfully apply vine fertilizer from mountain cracking, and reapply melon fertilizer. Extended information (1) seedling promotion fertilizer Seedling promotion fertilizer is generally applied within a week after transplanting of resistant melon seedlings or 4-5 leaf stages of direct seedling, and a small amount of fast-acting fertilizer is applied when the basal fertilizer is insufficient or the fertilizer effect of the basal fertilizer has not been exerted.

2) vine fertilizer can be carried out before and after the vine extension, generally when the melon seedlings grow to 40-60 cm, apply 10 12 kg of urea, 8 kg of superphosphate, and 13 kg of potassium sulfate per mu. After application, cover the soil and water it to promote the absorption of fertilizer. (3) Expanded melon fertilizer The expanded melon period is the period when the watermelon needs the largest amount of fertilizer in its lifetime, and many melon farmers will apply expanded melon fertilizer at this time, because the hole fertilizer is too concentrated, the root system around the fertilization point will be burned out, and it is also not conducive to the rapid decomposition and transformation of fertilizer; Therefore, it is best to use human and animal manure water and dissolved chemical fertilizer for melon fertilizer.
