Carrot planting method and time, with planting technology

Planting time is from February to March in spring and from July to August in summer. Land preparation: Sandy soil is suitable for soil preparation. After soil preparation, farm manure of about 2000kg per mu is applied as base fertilizer. Sowing method: each hole can put 6 seeds, soft soil can be properly deep sowing, otherwise it should be appropriate shallow. Seedling management: the distance between plants was adjusted to about 8cm. Water and fertilizer management: reasonable watering according to the growing period, watering once a day after emergence to keep the soil moist.

First, planting time

1. The planting time of carrots is divided into two crops, usually sowing seeds in July-August in summer, and then harvesting in November.

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

II. Land selection and preparation

The main results are as follows: 1. Before planting carrots, we first need to select suitable planting plots, which should ensure good permeability, high topography, dryness and plenty of pollution-free water sources around them. the general soil is mainly sandy soil, and the permeability of clayey soil is relatively poor, which is not conducive to the healthy growth of carrots.

2. The previous crops planted in the soil should not be cruciferous crops, and it is necessary to carry out rotation for at least 3 years, and then carry out soil preparation, turn the soil deeply, break the soil, make a high border, and keep the border surface level. Then apply about 2000 kg of farm manure per mu as base fertilizer.

Third, sowing method

The main results are as follows: 1. the main sowing methods are hole sowing and sowing, during which the sowing amount should be controlled and the seeds should be sprinkled on the soil evenly. If it is hole sowing, 6 seeds can be placed in each hole, and the sowing depth can be controlled according to the degree of soil looseness.

2. The soft soil can be sowed deeply properly, otherwise it should be shallow. If sowing in summer, it is necessary to cover the soil with straw plastic film, which is beneficial to improve the soil moisture conservation ability, promote the emergence of seedlings, and avoid being washed by Rain Water. Lead to soil consolidation, and reduce the emergence rate.

IV. Management at seedling stage

The main results are as follows: 1. After the emergence of carrots, it is necessary to appropriately increase the interseedling time, delay the determination of seedlings, and ensure the strong seedling rate of carrots. The interseedling time can be adjusted reasonably according to the sowing method. If it is sowing, when two true leaves appear in the seedlings, interseedling should be carried out for the first time.

2. Adjust the plant distance between strong seedlings to about 8 cm, and then carry out the second interseedling in about 11 days. if it is burrow sowing, the seedlings can be interspersed about 7 days after emergence, and once ploughing and weeding work will be carried out after the first seedling emergence. It is beneficial to promote the growth of seedlings.

V. Water and fertilizer management

1. If sufficient base fertilizer is applied, the amount of topdressing can be reduced appropriately after planting, usually between the breaking of white carrots and the expansion period, thin fertilizer and water can be applied once, and attention should be paid to control the concentration and fertilization position to prevent root burning. Carrots have a large demand for water during their growth, and regular and quantitative supply should be achieved during the period.

2. If the soil is short of water, it will have a great impact on the growth of carrot roots, such as spicy and hollow, but the water should not be too much, otherwise it is easy to cause diseases. Generally, it can be watered reasonably according to the growing period, watering once a day after emergence to keep the soil moist.
