Field management techniques for high yield carrots
Carrot cultivation wants high yield? The field management part is really very important. Although there are only four words in the field management, there are too many contents included in it. For example, cultivating weeding, water and fertilizer management, and diseased branches are all part of the field management. Let's take a look at the field management points of high-yield carrots.
I. Weeding
The weeding of carrots should be carried out in the morning, because carrots are a kind of light vegetables. Weeding carrots, chemical control, manual weeding, artificial weeding has a significant impact on the quality of carrots.
Second, colonization
Usually in the afternoon on a sunny day, the dense seedlings, inferior seedlings, and seedlings can be removed in time. The first time is when the carrot has one or two true leaves, and it is combined with shallow tillage and weeding, the seedling distance is 3 to 4 cm. The second time is carried out when the carrot seedlings have 5 to 6 true leaves, and the seedlings are 10 to 12 cm apart.
Third, watering
Carrot seeds absorb water very slowly, so the dry soil will cause the carrots to delay emergence, and it is easy to cause the lack of seedlings and ridges. Watering is continued 2 to 3 times during the period from carrot sowing to emergence. Soil moisture needs to be maintained at 70% to 80%.
Carrots are also an impatient vegetable. Remember to drain in time on rainy days. When the carrot grows to have a thick finger, it means that the carrot has entered the expansion period. At this time, the demand for water is extremely high. Usually, water is poured from ten days to fifteen days, not too much or too little.
Fourth, fertilization
Before the soil is cultivated, the base fertilizer should be applied. The organic fertilizer should be applied for 3 to 4 tons per 667 m2. After the fertilization, remember to carry out the deep turn. During the growth of carrots, it is generally topdressed twice. In order to prevent rooting, it is combined with watering.
The first top dressing is generally carried out within 20 to 25 days after emergence, with three or four true leaves, and the second is carried out after twenty-five, with 3 to 4 kg of calcium phosphate per 667 m2 and 7 kg of ammonium sulfate. , potassium chloride 3 to 4 kg.
Five, prevent green shoulders, convulsions
This step is very important, and it is one of the main factors affecting the fleshy root of carrot. When the carrot enters the vigorous growth stage of the leaves, it is necessary to pay attention to the amount of water and fertilizer, and carry out the cultivating seedlings. If convulsions occur, remove them promptly.
The above is the cultivation method of high-yield carrots. You must pay attention to the management of these major points. There are many crops that are inseparable from the field management.
