Carrot pollution-free cultivation techniques

Because carrots are rich in carotene and minerals such as calcium, phosphorus, and iron, they have a reputation as “small ginseng” and are increasingly favored by people. Now we will briefly introduce carrot pollution-free, high-yield, high-quality, and efficient cultivation techniques.

First, choose the land:

1. Carrot cultivation plots should be selected before the plot has not been planted cabbage, radish, barley blue and other vegetables in the plot, otherwise easy to make carrot disease.

2. Choose sandy loam soil with deep soil layer, rich organic matter, soft and well-drained. This type of plot is small in acidity, loose in soil, easy to enlarge roots of carrots, with less lateral roots and rich skin color.

Second, soil preparation, basal fertilization, sorghum:

1, soil plowing 30-35 cm. Combine 5,000 kg of decomposed organic fertilizer in Mushi, 25 kg of urea, 25 kg of superphosphate and 25 kg of potassium sulfate. It is required to evenly embed the soil below 6 cm from the topsoil.

2, playing fine soil blocks, leveling, do 1 meters wide, 10 meters long 畦 纵横 纵横 纵横 纵横 纵横 纵横 纵横 耙 耙 耙 2-3 times.

Third, species selection and sowing date, broadcast volume:

1. Variety: My county generally chooses Qianyang to be “Red Heart” and “Kuroda Five-inch”.

2. Sowing date: In early July in the reclamation area, it is advisable to plant seedlings at the end of 7 in Sichuan.

3. Sowing amount: 0.75 kilograms of seeds per mu. Spread the seeds evenly and peck the surface. Make the seeds 0.3 to 0.5 centimeters into the soil. Use a roller to grind the surface and pour the appropriate amount of water.

Fourth, field management:

1, weeding and weeding: when the thinning of 1 to 2 true leaves, the weak seedlings remain strong, 4 to 5 true leaves, and the seedling distance is about 10 cm. After the carrots emerge, weeds should be removed timely; combine with fixed seedlings, cultivator pine earth.

2, top dressing irrigation: the first top dressing should be carried out after Dingmiao, apply 5 kg of ammonium sulfate per mu, 2 kg of potassium sulfate. Seedlings in the 7-8 real leaf period for the second time dressing, apply ammonium sulfate 10 kg per kilogram, potassium sulfate 5 kilograms, both fertilization should be diluted with water and then poured into the ground. The first watering after sowing should be thorough, and the second watering should be appropriate, and then watering according to the situation of the public, to keep the field "see wet see dry."

V. Pest Control: Common diseases of carrots are black spot, black rot, and leaf blight. Pests mainly include underground pests, aphids, and root lice. For the control of black spot and black rot, good varieties were selected, rationally distributed, crop rotations were applied, organic fertilizers were added, weeds were used for weeding, no disease-resistant pests were cultivated, and the number of pests and diseases was reduced. At the beginning of the disease, 75% chlorothalonil WP was sprayed at 600 times; leaf blight was removed in a timely manner; aphids were treated with 5% quercetin and 10% imidacloprid 1500 times.

6. Harvesting and storage: timely harvesting, harvesting sufficient roots of the fleshy root before harvesting, premature and late harvesting will affect the character and output of carrots. Experienced can also be sampled to see the appearance of taste, appearance Full, smooth skin, apical fleshy, sweet taste, no fiber, you can harvest.
