How much is the Qilin melon seed of Cucurbitaceae? How do you plant it? How long will it take to sprout? How to raise seedlings?

Qilin melon is a variety of watermelon, which is generally mature and on the market in summer. it is widely planted because of its good taste, short growth cycle and fast benefit, but it is rarely planted in few areas because of its harsh growth environment. How much is the Qilin melon seed? How do you plant it? How long will it take to sprout? How to raise seedlings?

Seed price:

The market price of Kirin watermelon seeds is about 1280 yuan to 1300 yuan per jin. The factor that affects the price of Kirin watermelon seeds also lies in the differences between regions, so when buying, we should take the local price as the standard.

How long will it take to sprout?

In a day or so, you can see white. I'll see you in a week or so.

How do you plant it?

1. Land selection and land preparation. The selection of sandy loam, deep plough layer, drainage and irrigation of the field, it is best to focus on the piece, easy to manage. Before setting up the shed, we should unify the mechanical soil preparation, remove the base fertilizer and turn the soil deeply. Generally, 667m2 is applied with organic fertilizer 250kg, imported ternary compound fertilizer 50kg and superphosphate 50kg. According to the width of the greenhouse is 4.6 m, the sidewalk with wide 30em and deep 15em is opened in the middle, which is divided into 2 beds, each 2m.

2. Sprouting and sowing. Dry the seeds for one day before sowing. Soak in 55 ℃ warm water for 15 minutes for 30 minutes before sprouting. Stir while soaking. Or treat with 1% formaldehyde solution for 10 minutes, rinse with clean water, and then soak the seeds for 6-8 hours. Then the mucus on the surface of the seed was scrubbed clean, wrapped in a wet cloth, and germinated at a temperature of 28 ℃ ~ 32 ℃ (which can be accelerated by human body temperature or electric blanket). The seeds were generally sown in white after 24 hours.

Matters needing attention for seed germination:

First, do not sprout too dense or too thin.

Second, the humidity of budding should not be too high. In the process of sprouting, it should be observed and adjusted frequently, and problems should be solved in time.

Third, the humidity is not too high, pay attention to ventilation to accelerate germination. The soaking time of the seeds should not be too long and the water on the seeds should be drained.

Fourth, the length of seed sprouting should be no more than 3 mm.

Fifth, in the process of accelerating germination, we should often turn the seeds, promote the seeds to be heated evenly and increase air permeability, and wash them with warm water when they are found to be sticky or sour.

Seedling management techniques:

The main results are as follows: 1. The selection of seedling bed: the seedlings should be raised in the greenhouse, and the plots which are close to the cultivated field, with high dryness, shelter from the wind and sun, good light conditions and convenient drainage and irrigation should be selected.

2. Preparation of nutritious soil: nutritious soil is required to be loose, fertile and water-retaining, and should be composted more than one month in advance. The paddy soil which had not been planted with melons for more than 3 years was mixed with mature farm fertilizer, compound fertilizer, calcium magnesium phosphate fertilizer and plant ash, and then covered with film. ∶ mature farm fertilizer ∶ plant ash = 5 ∶ 3 ∶ 2 in paddy soil, while 5 kg calcium magnesium phosphate fertilizer and 2 kg crushed compound fertilizer were added to 1 cubic meter nutrient soil. In the process of mixing, you can use 50% carbendazim 600 times solution or 1% formalin solution to disinfect, sprinkle evenly, dry and sieve.

3. Nursery bed preparation: generally, about 400 watermelons need to be raised per mu. Set up the seedling shed ahead of time to make an electric hotbed. The nursery bed is 1.3m wide and 5cm deep, with a length of 5cm. Cover it with a layer of old film for heat preservation, fill it with 2 cm thick grain chaff, cover it with a layer of disease-free fine soil, flatten the soil surface, and then spread an electric hot line for heating. Every 10 square meters of seedling bed cloth is 1000 watts of electric hotline, sparse in the middle of the bed and slightly denser on both sides. Connect the power supply and switch, select the 10 cm × 10 cm plastic nutrition bowl, install the nutritious soil and arrange it on the electric hot line of the seedbed, cover the film to keep warm.

4. Accelerating germination and sowing: one day before sowing, soak in 55 ℃ warm water for 15 minutes for 30 minutes, while soaking and stirring. Or treat with 1% formaldehyde solution for 10 minutes, rinse with clean water, and then soak the seeds for 6-8 hours. Then the mucus on the surface of the seed was scrubbed clean, wrapped in a wet cloth, and germinated at a temperature of 28 ℃ ~ 32 ℃ (which can be accelerated by human body temperature or electric blanket). The seeds were generally sown in white after 24 hours. Two days before sowing, the bottom water of nutritious soil was fully watered, and the seedling bed was preheated by electrification. When the soil temperature was controlled above 25 ℃, the seeds could be sowed. Sowing in the morning on a sunny day is appropriate, one grain per bowl, seeds should be placed flat, cover fine soil 0.5 cm after sowing, cover with plastic film after proper sprinkling, and build a small arch shed to keep warm.

5. Seedling stage management

① temperature: keep the temperature of the small arch shed higher before emergence, 28 ℃ ~ 30 ℃ in the daytime and 18 ℃ ~ 25 ℃ at night. When 30% of the seedlings are unearthed, remove the plastic film covered on the nutrition bowl and the small arch shed film for ventilation. After emergence, the temperature in the greenhouse was about 25 ℃ in the daytime and 15 ℃ ~ 18 ℃ at night. If the temperature is insufficient during the seedling raising, the electric heating line should be used to turn on the temperature.

② humidity: the moisture management of nutritious soil in seedling bed adopts the principle of "should be dry rather than wet", watering as little as possible after emergence to true leaves, and then depends on the dry and wet condition of nutritious soil. If the soil is not white, it should be watered thoroughly, and watering should be carried out at noon. Under the condition of ensuring the temperature, the greenhouse should be ventilated as much as possible to reduce the humidity so as to prevent the occurrence of diseases. If the rain begins to clear and the seedling leaves wilt, the seedlings should be properly covered with shading net to promote the seedlings to return to normal. Stop watering 5-7 days before transplanting. There is generally no need for topdressing at the seedling stage, if the seedling growth is weak, 0.3% urea and potassium dihydrogen phosphate can be used for extra-root topdressing.

③ light: let the seedlings see more light at the seedling stage, and remove the small arch shed film during the day. Artificial lighting should be carried out in case of continuous rainy days, and 300 watts of incandescent light bulb should be used for every 10 square meters of seedling bed.

Prevention and control of ④ diseases and insect pests: because of the low temperature and high humidity of seedling bed in early spring, many diseases such as quenching disease are easy to occur. In addition to reducing the humidity in the greenhouse as much as possible, Purek, Dasheng and Metalaxyl mancozeb can be used to control. In case of continuous low temperature, weak time and rainy days, the medicament can be mixed with dry soil and sprinkled in the seedbed. Spray 50% carbendazim 600 times solution into the field before planting.
