Planting method and time of carrots

Planting time is from February to March in spring and from July to August in summer. Select improved varieties: select five-inch varieties with high temperature resistance, stable yield and good quality. Selecting land for fertilization: sand loam and river silt loose soil are suitable, and organic fertilizer 3000kg and potassium sulfate 10kg are applied per mu. Soaking and sowing: soak the seeds in warm water for 12 hours, then sow the seeds in the trench, and trample in the trench after planting. Post-planting management: ploughing and loosening the soil in time and removing weeds.

First, planting time

1. Carrots are usually sown in July-August in summer and then harvested in November.

2. With the demand of the market, there are spring sowing varieties, which are mainly in February-March. If the temperature in the open field is low at this time, you can choose to sow seeds from mid-late March to early April, because the time of bolting will be advanced if sowing too early, and it is easy to flood if sowing too late.

Second, select improved varieties

The Hongyu five-inch variety with high temperature resistance, stable yield and good quality was selected. The variety was planted in Dali Shayuan without bolting and developed normally, and the seed consumption per mu was 150-200g.

3. Selecting land and fertilizing

The main results are as follows: 1. The suitable planting land of off-season carrot is the same as that of autumn and winter carrot, generally sandy loam and river silt loose soil are suitable, and the amount of fertilizer should be determined according to soil fertility. Generally, the field is based on bottom fertilizer, and organic fertilizer 3000kg and potassium sulfate 10kg are applied per mu.

2. When there are underground pests, 2 kg 3% carbofuran granules are applied per mu. In order to avoid the occurrence of weeds, 48% trifluralin 80ml per mu can be applied, the ground will be sprayed with water, the ground will be turned deep 25cm, and the soil can be loosened and broken as far as possible.

3. To build a ridge with 120cm width and 30-50cm length, if the soil is short of soil moisture, it can be irrigated first and then prepared.

Fourth, soaking and sowing seeds

The main results are as follows: 1. Soak the seeds in warm water for 12 hours before sowing, and then remove the sand. The proportion of sand planting is 1:6. In order to plant sand evenly, a trench rake (3 bamboo slices on the wooden beam, the bamboo distance is 20cm, the bamboo thickness is 0.8-1cm, the length is 20cm, the upper width is 3cm, and the lower width is 2cm) is used to make a ditch with a depth of 0.5cm.

2. Then sow seeds along the ditch, trample along the ditch after planting, push and pull the ground once with nail rake, and sow film at ridges. The height is 5-8cm, the width under the ridge is 40cm, the width at the top of the ridge is 50cm, the center distance of the ridge is 50cm, the row spacing is 18cm, and the plant spacing is 10cm.

3. Then covered with plastic film (with plastic film), the width of the film is 40cm, and the seedlings should be drilled and released in time after emergence to ensure that the soil moisture should be fully filled.

V. Post-planting management

The seedlings were determined in time before and after growing 4 leaves, and the plant spacing of strip sowing was 12-15cm, leaving about 22000 seedlings per mu. After entering May, the temperature increased, watering in time in case of drought, timely ploughing and loosening soil, and removal of weeds, so as to keep the ground loose and unconsolidated all the time.

VI. Harvest listing

Out-of-season carrots can be on the market in July, and the harvest period can last more than 20 days.
