When will melon seeds be sown?

Melon seed is a very popular leisure snack, which can also be used to extract oil. it has high economic value and attracts a large number of farmers to plant. So, when will the melon seeds be sown?

When will the melon seeds be sown?

In general, melon seeds are sown from March to April, and the suitable temperature for sowing is 18-25 ℃, and sprouting is about 5-7 days after sowing.

Second, the growing environment for planting sunflower seeds

1. Temperature

Sunflower is a temperature-loving and cold-tolerant crop, which has strong adaptability to temperature and strong low temperature tolerance. Seeds begin to germinate when the local temperature is more than 2 ℃, germinate and take root at 4-5 ℃, and meet the needs of seed germination and emergence when the ground temperature reaches 8-10 ℃. During the whole growth process, sunflowers can grow normally as long as the temperature is not lower than 10 ℃.

2. Moisture

Sunflower is a crop that consumes a lot of water, with tall plants, many leaves and dense leaves, and its water absorption is 1.74 times that of corn, but because its growth and development is synchronized with local rain and heat, the contradiction between water supply and demand is not prominent, and the water requirements of different growth stages are very different. There is not much water from sowing to budding, the peak of water demand from budding to flowering, and more water from flowering to maturity.

3. Lighting

Sunflower is a short-day crop, which is not very sensitive to sunlight. Like plenty of sunlight, its seedlings, leaves and disk have a strong phototropism. Sufficient sunshine and strong seedlings can prevent overgrowth. Sufficient sunshine in the middle growth stage can promote the vigorous growth of stems and leaves, normal flowering and pollination, and improve the seed setting rate. In the later stage of growth, the sunshine is sufficient, and the grain is full.

4. Soil

Sunflowers have low requirements for soil and can grow in all kinds of soils, ranging from fertile soil to dry land, barren and saline-alkali land. It not only has strong saline-alkali tolerance, but also has salt absorption ability. At the same time, sunflower has developed root system and strong drought resistance. Moreover, the root and stem aerosol tissue of sunflower is well developed, which is very resistant to waterlogging.

The sales of melon seeds have always been good, and sunflower seeds are also a high-grade and healthy source of oil, suitable for large-scale planting.
