How much is the price of carrot seeds per jin? When will you sow and reap? How long is the growth cycle? How do you plant it?

Carrots, also known as carrots or kanxun, are varieties of wild carrots and are widely cultivated all over the country. Distributed in Europe and Southeast Asia. So how much is the seed price per jin? When will you sow and reap? How long is the growth cycle? How do you plant it? I learned from the six carrot growers in Hunan that at present, the better varieties of carrots are five inches of Kuroda in Japan, five inches of improved Kuroda, Hiroshima, Yingshanhong and five inches of South Korea, and so on. There are also local carrot varieties such as Xiaodinghong, Zhadihong, and other traditional farm varieties in China, which can be planted at a price of about 55 yuan per jin.

When will carrots be sown and harvested?

The main results are as follows: 1. In the cultivation season, carrots are mainly sown in autumn, and late August is suitable for the middle and lower reaches of the Yangtze River. If the seeds are sown from March to April, in the mountainous areas with higher elevations, because the temperature is still low, film mulching is feasible in the early stage.

2. Carrots are sown in summer and autumn and harvested in autumn and winter. According to the characteristics that the seedling stage needs high temperature, the root hypertrophy period requires cool, and the climate and varieties of different regions arrange the sowing time, so that the seedling stage is in the high temperature season, and the root hypertrophy period is in the cool season.

How long is the growth cycle of carrots?

The vegetative growth period of carrots is 80,140 days. The germination period is about 10-15 days, the seedling stage is about 25 days, the peak leaf growth stage (also known as rosette stage) is about 30 days, followed by the fleshy root growth period, 30-70 days. The seeds can germinate at 4: 6 ℃, and the optimum germination temperature is 20: 25 ℃. The leaf growth has strong adaptability. The taproot expansion period requires 13: 23 ℃, and the night temperature is 13: 18 ℃. The seedling stage can be arranged in the month when the temperature is higher or lower, so that the product growth period is at the best temperature.

How do you grow carrots?

1. The suitable temperature for carrot planting.

Carrot is a semi-cold-tolerant vegetable, the suitable temperature for germination is 20-25 degrees Celsius, the suitable temperature for growth is 18-23 degrees Celsius during the day and 13-18 degrees Celsius at night. Too high and too low temperature are disadvantageous to the growth of carrots, and carrot roots are well developed. deep ploughing the soil plays an important role in promoting root growth and fleshy root fertilizer.

2. Soil requirements for carrot planting.

The soil should be deep sandy loam, and ph5-8 is more suitable. Soil moisture is required to be 60-80% of the maximum soil water holding capacity. If there is too much water in the early growth stage and the aboveground part grows too vigorously, it will affect the inflated growth of fleshy roots. If there is not enough water in the later stage of growth, the taproot can not be fully expanded, resulting in a decrease in yield. Too sticky soil or the application of immature base fertilizer will hinder the normal growth of fleshy roots and produce abnormal roots.

3. Watering and fertilization of carrots at seedling stage

When the seedlings had 7-8 leaves, the seedlings were hoed and squatted deeply while the soil was wet, which promoted the extension of the main root and the development of fibrous root, and inhibited the excessive growth of the leaves. After 10-20 days, when the fleshy root was obviously dilated, it began to be fully watered and the soil was often kept moist. Ammonium sulfate 2kg / mu, calcium superphosphate 3kg / mu, potash fertilizer 2kg / mu. When fixing the seedlings, the combination of watering ammonium phosphate 10 kg per mu, potassium chloride 3-4 kg, to promote the seedling to thrive and grow rapidly. At the beginning of fleshy root growth, quick-acting organic liquid fertilizer or ammonium phosphate, potassium chloride and so on were applied. Spring carrots are harvested 90-100 days after sowing, while autumn carrots are harvested and stored before the advent of severe winter.
