Entering August is a key period for carrot field management. Based on our many years of practical experience, we now briefly summarize the carrot field management techniques as follows:
1. Intercropping, cultivating and weeding
In the first time, the seedlings grow 1-2 true leaves in the seedlings, and the seedling height is about 3cm. The seedlings are kept at a distance of about 3cm, and the weeding soil is shallowly cultivated between the rows to promote the growth of the seedlings. The second seedling grows 3-4 true leaves in the seedlings, and the height is about 13cm. At this time, it is also possible to combine the cultivating and weeding to fix the seedlings. The seedling plant spacing is 13-15cm, and the seedlings are 3 to 40,000.
2, water and fertilizer management
Watering Before the seedlings, keep the soil moist. After the seedlings, the soil will be dry and wet. During the expansion period of the fleshy roots, the soil is kept moist, the water supply is ensured, water is timely and timely, and the water in the field is removed after the rain to prevent cracking and rotting roots due to uneven water volume.
After the seedlings are fixed, the nitrogen fertilizer (N) is applied in an amount of 4 kg per mu (water 8.7 kg), and the potassium fertilizer (K 2 O) is applied in an amount of 5 kg per mu (10 kg of potassium sulfate).
3. Pest control
Seedling stage rickets and blight control can be used to dilute the roots with 72.2% Plex water agent 5-7.5 ml per square meter plus 2-3 liters of water. It is best to use the artificial capture method for the tigers and cockroaches. When the amount of insects is large, the poison bait can be used to kill the method. Use the crystal trichlorfon to mix the bran or oil residue, and sprinkle it in the evening or near the roots.
