Carrot has always been loved by the people, not only sweet taste, but also eyesight and other effects. How to grow organic carrots? The cultivation technology of organic carrots is brought by the farmers' friends who need it!
First, work on the ground
The base fertilizer is fully fermented with homemade organic fertilizer, mushroom residue: chicken: vegetable and vegetable waste material = 1:4:2, 2500 kg per acre, combined with ploughing and full tillage layer for full fertilization.
Or apply a full-fertilized compost, a fertilizer or animal manure urine 3000~4000 kg per mu (or 150 kg of decomposed peanut cake fertilizer, or 150 kg of decomposed soybean cake fertilizer), 40 kg of phosphate rock powder, 20 kg of potassium ore powder, Apply when preparing the ground.
The soil is deeply ploughed 25~30 cm, leveled, squashed, ditched, and smashed. Each 畦 wide groove is 1.5 meters, the groove depth is 25 centimeters, and the distance is 50 centimeters.
Second, sowing seedlings
Cultivation season
In the Yangtze River basin, spring dew cultivation, planting in mid-March in March, should be broadcast live; autumn open field cultivation, planting in mid-late July to August, should be live.
2. Seed treatment
Seeds are sown for 2 days before sowing. The bristles on the seeds are removed. The seeds are poured into 40 ° C water for 2 hours. The drained water is removed and germinated for 3 to 4 days at a temperature of 20 to 25 ° C. When the seeds are white You can sow.
3. Live broadcast
After the planting is carried out, the seeds and the soil are mixed and sown, and the amount of seeds per acre is 500-800 g. After sowing, the soil is covered with a layer of thin soil and watered. In the open field cultivation in spring, it is covered with a colorless film.
Third, field management
Weeding
After emergence, artificial weeding in time. In the case of 3 to 4 true leaves and 13 cm in height, the seedlings were planted at a distance of 6 to 7 cm. Remove weak seedlings and inferior seedlings, and choose to keep healthy seedlings and excellent seedlings.
2. Fertilizer management
Micro-sprinkler irrigation to keep the soil moist, the soil moisture in the growing season is about 60%. The topdressing fertilizer should be applied with quick-acting fertilizer, and the long-term can be divided into three times. The fleshy roots were firstly topdressed during the rapid expansion period, and then applied once every 1S day for a total of three times. The top dressing can choose the leachate of rice bran cake, bean cake or rapeseed cake. After fully decomposing, it can be used as a root dressing for 10 times of water, and directly topdressed with water for 5 times. Or 150 kg of animal manure per acre combined with watering, and appropriate application of biological potassium fertilizer.
3. Soil management
Carrot roots generally show little soil, but because of the rain or the soil layer watering, when the soil is solid, the soil will be exposed on the top, and it will be cyan by direct sunlight, which can be combined with cultivating and weeding.
Fourth, pest control
Black spot
Before the onset or early onset, spray 7% copper hydroxide wettable powder 500 times, spray once every 7~10, spray 2~3 times, and stop 7 days before harvest.
2. Bacterial soft rot, sclerotinia, etc.
Spray with 0.5% emodin methyl ether aqueous solution 600 times.
3. Locust
It can suspend 20~30 yellow boards per acre to kill, use 1.5% pyrethrin water 600~800 times liquid, or 0.3% sinensis emulsifiable oil 100 fog. In the initial stage of pests, use 0.3% matrine water agent 400 Double liquid spray, spray once every 5~7 days, the pests will be in the period of 3~5 days, for 2~3 times.
4. Wax
Use 1.2% matrine powder per acre 2~2.5 kg, or 2 kg of Metarhizium per acre, mix 50 kg of fine soil, and sprinkle it into the soil during cultivating.
5. Yellow stripe jumper
It can be sprayed or rooted with 700 times of rotenone.
V. Timely harvesting
Generally, after 90 to 100 days of sowing, it can be harvested in batches. Picking at the right time according to the characteristics of the variety. Watering 2 days before harvesting to make the soil moist; manually pull out, clean, leave some stems and leaves according to sales demand; prevent mechanical damage, and enter the grading and packaging workshop in time.
About the organic carrot cultivation technology points Hui Nong network Xiaobian today to summarize this for everyone, farmers who need to continue to pay attention to Hui Nong network later, there are more different agricultural technology knowledge!
