Breed and season

Japanese carrot varieties are F1 hybrids with high yield, quality, big, short, low fiber, bright red color, long-term preservation, average weight of 300g / tuber, yield of 1.2-1, 5 tons / rod.

Early crop: sowing July 8, harvest 10 - November. Main crop: sowing 11-12 months, December harvest, January next year. Late crop: sowing 1-2 months; harvest 4 - 5 months.

Soil preparation, fertilizer application

Choose light soil, sand, actively irrigate. If acidic soil pH <5.5, need to apply 20-25 kg of lime / rod, apply before harrowing for the last time. Make soil carefully, pick up weeds, go up to 20-25cm high, 1- 1.2m wide. Basal fertilizer is mainly, the amount of lining fertilizer for 1 sao includes: Manure of 0,7- 1 ton; Supe unicorn 7- 10kg; potassium chloride 3 - 4kg; urea protein 1 - 2kg. Mixed fertilizers and then spread into beds when making soil. Can apply 30kg of NPK fertilizer (5: 10: 3) + 2kg of potassium / sao instead of nitrogen, phosphorus, potassium for more economic efficiency.

Drills

Carrots are instant, scattered. The amount of seeds needs 160-180g / rod. The early crop sowed, the main crop was sown thick.
Before sowing, put seeds into a cloth bag, lightly beat and break all the feathers, then mix seeds with humus at a ratio of 1: 1, put them in the watering pot, stir well, then cover, after 8 - 10 hours to water again. Incubate 2 days and nights, then sow, seeds will grow evenly. Sow the seeds and scratch the rakes again and again a few times for the soil to fill the seeds, then cover them up.

Take care of

Watering: Sow the seeds and water immediately, irrigate once a day, until carrots grow evenly 3-5 days once. When tubers begin to grow, just water once a week to ensure humidity of 60-70%.

Pruning and cultivating: When the tree is 5 - 8cm tall, prun the first time, remove the bad trees. When the tree is 12-15cm tall, prun the second time (pruning the tree), leaving the tree 10-12cm away from the other tree, the other row 20cm away from the other. Keep density of 12-15 thousand trees / rod. Tilling the soil when the plant is small is a technical measure that has an effect on productivity, because in addition to making soil loose for growing roots, it also works to kill weeds, ensuring adequate light regime for carrots photosynthesis. If poorly grown plants can be applied topically by adding manure to water soaked with super phosphate + 1-2kg of urea / rod. After pruning the tree, if a poor growing tree can irrigate again with the same amount of fertilizer.

Can use fertilizer through K-Humate leaves or KH + Multi-K (13: 0: 46) to spray carrots 2-3 times, each time 10 days apart, the yield can increase by 20-30%.

It is necessary to actively control some pests and diseases such as leaf-eating worms, anthracnose, late blight, leaves .

When the tubers are full, the root leaves become yellow and about 15-30%, then harvest.
