A, green carrot stubble arrangement?

Local wheat, peas, vegetables, melon stubble for planting green carrot plot stubble, in order to facilitate the harvest of the previous crop for deep plowing and sun exposure resting on the ground sterilizing pests, reduce pests and diseases, conducive to the growth of green carrots, and seriously do a good job of rotating stubble, planting green carrots at intervals of 2 years of rotating stubble is appropriate.

Two, green carrot land fertilization, do bed ?

The green carrot choose soil deep, fertile, good irrigation and drainage conditions of the plot. Planting plots in the previous crop harvest, every 667 square meters into the fully rotted high-quality circle fertilizer 4000 ~ 5000 kg, 75 ~ 100 kg of rotted cake fertilizer or ternary compound fertilizer 50 kg to do the base fertilizer, turn over 30 cm or so, fully exposed to the sun, harrowing to do the beds, and more than the use of flat-bed cultivation.

Three, green carrot sowing ?

The green carrot varieties are mainly two tassels and two varieties of small tassels. Two large tassels individual larger, raw food cooked, pickled can be. Higher yield, generally a single weight of about 500 g, the average yield of 52.5 ~ 60.0 t / hm2, the growing period of 90 d or so; small tassels should be eaten raw, quality, individual small, slightly lower yield, generally a single weight of about 400 g, the average yield of 45.0 ~ 52.5 t / hm2, the growing period of 80 d or so.

Four, growth temperature

The growth of green carrots suitable temperature range of 10 ~ 25 ℃, below 6 ℃ to stop growing, more than 30 ℃ growth is seriously impeded. Green carrot sowing period: should be sown at the right time, not too early or too late, if sown too late, the late temperature is reduced, not conducive to the expansion of fleshy roots. In the northern region, green carrot sowing period to August 1 ~ 5 or so is appropriate.

Five, green carrot seeding quantity

Each 667 square meters with a seed amount of 0.8 pounds or so, more strip sowing, row spacing 30 × 20-22 cm, planting 135,000 to 15.0 million plants / hm2, and timely seedling thinning, seedling period to be divided between the seedling, 5 to 6 leaves when the seedling is fixed. Sowing depth 1.5 cm. After sowing, cover the soil with about 2 centimeters of soil and pressurize it in time. When the moisture is good, the second day with grass seedlings can be dragged once; when the moisture is poor, mulching and compaction and timely spray water.

Harvesting management

The different varieties and sowing time, harvesting time is not the same, generally after the fleshy roots are sufficiently fattened for the harvesting of the appropriate period. Harvesting too early, low yield; too late, easy to suffer frost damage or chaffing, pumping and reduce quality. Spring sowing spring radish sowing general 50-60 days after harvest; summer radish growth fast, sowing 45-60 days after harvest; fall and winter radish sowing 70-100 days after harvest.

As for the fleshy roots of most of the varieties exposed on the ground, to be harvested in time before the frost to avoid freezing, fleshy roots all in the soil varieties, can be harvested late to touch high yield. Radish yield, generally large fall and winter radish mu yield 3500-4000 kilograms, high-yielders can reach more than 5000 kilograms, medium-sized radish mu yield 2500-3000 kilograms; spring radish and summer radish mu yield 1000-1500 kilograms; four seasons radish mu yield 600-1000 kilograms.
