Dryland wheat aphid carrot cultivation technology

In the dryland, the wheat, carrots and radishes were harvested after the wheat was harvested at the end of June and early July. Since land has fewer pests and diseases after wheat is changed, the carrots are generally not sprayed with pesticides during the whole breeding process. The products are of high quality and have good economic returns.

First, the soil preparation Fertilizer wheat timely deep-flip 20 cm after harvesting, breaking the soil and rubbing debris, picking up the debris, leveling and polishing, so that the soil texture is loose, creating good conditions for carrot root swelling. At the same time, 2000-2500 kg of decomposed organic fertilizer, 15-20 kg of phosphate fertilizer, and 40-45 kg of potassium sulfate were applied in combination with the site preparation.

Second, science sowing

1. Variety selection Generally, carrots with strong heat-resistance, tender meat, small pillars, sweet and crisp taste, and bright red color are selected.

2, seed treatment before sowing should be planted 1-2 days, and remove the bristles on the seed, easy to seed evenly, so that the seeds and soil contact closely, fully absorbent, is conducive to germination.

3, sowing 0.5-0.75 kg per 667 square meters, can be broadcast or broadcast. During the sowing, the width of the earthworm depends on the topography. The cultivated earthworms can be flattened or narrowed to facilitate irrigation. Generally, a width of 1.5 meters is appropriate. Sowing when sowing seedlings, spacing 25 cm, covering 1.5 cm is appropriate. Spreading is to sow the seeds directly on the ground, and then sweep the soil with a broom. Due to the high temperature and evaporation of water at that time, wheat straw or other crop stalks could be used for sun protection to facilitate emergence.

Third, field management

1, rushes of grass due to abundant rainfall, carrots grow slowly in the early period, while weeds grow fast, so sward sward loosing soil is very important to promote seedling growth.

2. When the seedlings grow 2 true leaves, the first time the seedlings are made, the seedling distance is kept 2-3 cm, and the seedlings have 3-4 true leaves for the second time.

3, Dingmiao carrot seedlings grow to 4-5 true leaves when the Dingmiao, remove dense, bad and diseased plants, spacing 10 cm, leaving 20,000 per 667 square meters of left and right.

4. The medium-tillage till about 60 days after the sowing of the cultivator, combined with cultivating and weeding, in order to loosen the soil and promote the expansion of the fleshy roots.

5, watering carrots have strong drought-resistance ability. The seedling stage needs less water, and it is necessary to properly control the moisture during the prosperous period of the leaf sector to prevent the crop from growing on the ground and strengthen the cultivator to maintain balanced growth between the ground and the ground. The fleshy root hypertrophy period has the most demand for water and should be watered in a timely and reasonable manner to keep the soil moist. If watering is insufficient, the fleshy roots are fine and of poor quality. In addition, if the water supply is not uniform, it will easily cause cracking of the fleshy roots, affecting the commodity rate.

Fourth, harvest carrots from sowing to harvest the number of days vary by species, generally about 80-90 days early maturing varieties, 100-120 days of late-maturing varieties. After the carrot root is fully swelled and matured, it can be harvested and packaged. Early harvesting is of poor quality and low yield; harvesting too late flesh roots are easily corked, sweetness is reduced, quality deteriorates, and commodity value is lost.
