Watermelon 8424It is the pre-cooked species of watermelon, cosmopolitan fruit, red fruit, fragrance, tenderness, juicy juicy, non-precipitous, with an average weight of 3kg per melon. Now, let's find out with jing, how do you grow the 842? 842 watermelonPlantation techniquesAnd grow time。
I. Origin of 8424:
Our country is the world's comparative watermelon, but it is not from china. The watermelon originated in africa as a wild plant of thorium and was later artificially grown into a watermelon for food. The watermelon was grown by egyptians 4,000 years ago, then moved from the mediterranean coast to northern europe, and then to the middle east, india and so forth, and in the fourth and fifth centuries, from the west into our country, so it was called a “watermelon”。
Ii. 8424 watermelonVarieties
Early childhood, 8424, is an early-maturity watermelon that blooms until the fruit matures for about 28 to 45 days and grows in moderate growth and good fruit. The fruit is round, the green skin is covered with green and narrow bands, the appearance of skin, red radish, the sense of pretense, and the centre is 11-12 degrees sugar. On average, more than 10 pounds, 600-700 pieces, weighing 3-4 kg high, are suitable for both or three-cranium whole branches, fertile soil and moderate irrigation. It is suitable for pre-cooked membrane cover and field cultivation, artificially assisted pollination should be carried out in the shower and harvest should be appropriate at maturity. Water should not be poured three days before the pick-up, in order to prevent cracks and reduce sugar levels, and reference should be made to local cultivation practices. It is suitable for long seasons of pre-maturity or protected areas. At the end of march, in early april, planting took place at a distance of 2. 4 x 0. 8 metres, with approximately 250-300 acres planted and three cranium branches collected in due course。

Iii. Efficient and high-yield cultivation techniques for watermelons
1. Land selection
Guadilla has chosen to plant watermelon with a heavy burden and cannot be associated with melon crops such as cucumbers, melons and prunes in order to prevent the occurrence of atrophy, usually with seven to eight years of drought, five to six years of water and three to four years of water. It is desirable to select a melon field with a high level of dry terrain, a sunwind, a deep and loose soil, good drainage and water-filled conditions. (c) to improve the compounding index in terms of tailor-made arrangements. My suburbs, corn, sweet potatoes, grains, soybeans, etc. The peanuts were used with great care. The use of a condom should be a reasonable combination, such as spinach, carrots, oil, potatoes, etc. There have been developments in cotton fields and wheat fields, as well as in wheat summer broadcasts, with over 1,000 acres broadcast in wuqing county, and in small-scale villages, where many harvests can be planted using wide-spreading, making full use of land, light heat and increasing economic efficiency。
Land as a whole
In spring, guacamole fields reach 20 to 30 centimetres before winter, with no mud, tan, fertilizing soil, freezing pests and gathering snow. In the early spring, when appropriate, you can use the swirling. It is then planned to dig a guacamole (also known as the guacamole). Digging can thicken the living layer of the earth, facilitate the extension of the roots and allow for concentrated application of base fertilization. Guadeloupe's going for something, north and south. At a distance of 1. 6-1. 8 m, the 50-60 cm wide and 40 cm deep ditches were dug, and 20 cm of cousins were placed on the south side of the ditch and tish on the north side。
Seeding
The standard for open seeding during seeding is 10 cm and temperatures are stable above 15°c, and the final frost is over when seeding occurs. My suburbs are usually on 15-20 april. If it's a membrane lid, it can be broadcast 2-3 days late. In the event of an empty membrane lid, seedlings to the two real leaves grow under the membranes and spread more than half a month before the open ground. If the membrane is covered with a small bow shed, planting may be desirable in mid-march and late. The seedlings were planted in early march and planted with small bow sheds in early april. The wheat specs fit 20-25 may. On july 15-30, it was appropriate to broadcast the summer in order to avoid the rainy season。
4. Field management
1. Cultivation in spring. With a focus on securing and raising the temperature of the earth, the plowing of the plentiful soil before breaking the heart gives root. The 1 real leaf grows and grows. When the 2 real leaves spread (cruise), the grooves fatten the seed. Each urea application, ammonium dimethyl, and 2-3 grams each, be careful that the seedlings are applied slightly, 8-10 centimetres away from the seedling, so that it is not too concentrated to allow for fatting. Water can be poured as appropriate. The 4-6 leaf needs to be sprouted, fertilized and properly watered. In the field, weeding is widespread once or twice. It is not appropriate to trap a pebble early, so that the plows do not hurt the roots。
General covered cultivation. The focus is on early control of underground pests. Watch the weather forecasts, the seedlings must be cold-proof, and they generally do not catch fat or water。
This is how 842 watermelons are grown. It is hoped that this will help you learn more about watermelon cultivation techniques and how to grow them
