Do you have to bury all the radishes when you plant them?

When planting safflower tree turnips, do not bury them all, and generally they are epiphytic to trees in moist mixed forests.

1. Carrots are suitable for cultivation in moist, deep soil and well-drained soil, generally sown from late August to mid-September, and harvested from November to December.

3. When sowing, water or manure should be poured first, and then sown and cover the soil, so that the seedlings have a larger capacity.

3. When sowing, first mix seeds with a new high-fat film, and then sow 5-7 seeds per nest, and cover the soil about 2 cm thick after sowing, which should not be too thick. At the same time, with the spraying of 800 times of the new high-lipid film, moisture retention and waterproof evaporation, sun protection and drought resistance, heat preservation and antifreeze, soil layer compaction, suffocation and isolation of pests and diseases, and improve the emergence rate.

4. When the carrot seedlings emerge, it is necessary to time the seedlings (that is, even the seedlings) to avoid the seedlings crowding each other or poor light, but we must master the principle of early seedlings and late seedlings. Generally, when the plant has 1-2 leaves, it can be homogenized once, leaving 3 plants in each nest; When there are 3-4 leaves, the second seedling leveling is carried out; When there are 5-6 leaves, the seedlings are fixed, and 1 plant is left in each nest.

5. After transplanting the seedlings, spraying the new high-lipid film can effectively prevent the evaporation of water on the ground, seedling diseases and pests, shorten the seedling retardation period, quickly adapt to the new environment, and grow healthily.

How to fertilize? 1. The basal fertilizer organic fertilizer is applied as basal fertilizer at one time, and 5-6 kg of urea, 13-17 kg of diammonium phosphate and 5-7 kg of potassium sulfate are applied per mu.

2. Top dressing. In the early stage of fleshy root expansion, 11-13 kg of urea and 8-9 kg of potassium sulfate were applied per mu; In the middle stage of fleshy root expansion, 9-10 kg of urea and 5-6 kg of potassium sulfate were applied.

3. Foliar spraying of calcium nitrate and boric acid 2 3 times in the middle and late stages of root topdressing to prevent calcium deficiency and boron deficiency; Foliar potassium phosphate sprays can improve yield and quality.

The carrots are planted in two crops, and the seeds are sown in the summer months, and the cherry blossoms are harvested in November. Spring-sown varieties are now available, which should be in February-March, and in the open field from mid-to-late March to early April. It is suitable for loam soil with deep soil layer and good drainage effect, and suitable seeds are selected to soak in water to promote germination, and then sow in the soil, pay attention to watering and weeding.

1. Planting time.

Carrots are planted in two crops, mainly in the summer, when the seeds are sown in the month so that they can be harvested in November. With the demand of the market, now there are spring sowing varieties, the time should be early in 2-3 months, if the temperature in the open field is low at this time, you can choose in mid to late March to early April, sowing too early to draw the time accordingly earlier, sowing too late is prone to waterlogging.

2. Planting technology.

1. It is suitable for growing in loam soil with deep soil layer and good drainage effect, and clay soil needs to ensure good drainage, which determines whether the cultivation is successful.

2. Screen suitable seeds, soak them in warm water of 37 before sowing, wait for 12-16 hours and then take them out, take them out and dry them in a cool place, which can be conducive to the emergence of seedlings in the later stage.

3. Before sowing, the soil should be raked several times to ensure that the surface layer is flat, sprinkled with seeds, covered with the soil layer, in order to ensure uniform sowing, you can mix sand bushes in it.

4. After sowing, pour enough water to ensure that the soil is moist so that the seeds are full of vitality. They emerge very slowly, and weeds tend to grow first, so pesticides need to be sprayed to get rid of weeds.

1. Apply sufficient base fertilizer and fine land preparation.

Choose sandy soils that are irrigated with natural water sources. Apply 2000kg of organic fertilizer per mu as base fertilizer, deep dry stubble and rake crushed, and then make a deep ditch and high furrow, and the furrow surface is flat to avoid water accumulation after rain.

2. Sow seeds at the right time and plant them reasonably densely.

Generally sown in May and August or point (hole) sowing, sowing amount mu, sowing to be even, hole sowing of the general 5 7 grains of holes, hole spacing 10cm square. After sowing, the soil thickness is about 2cm, the loose soil should be sown a little deeper, the clay heavy soil should be slightly shallow, the summer sowing should be covered with chaff, grass ash and other things in addition to the covering soil, and it can also be covered with a shade net, but the seedlings must be covered at night after the seedlings are all together, so as to maintain moisture, ensure that the seedlings emerge quickly and neatly, and avoid soil compaction due to heavy rain erosion hinders the emergence of seedlings.

3. Field management.

1) and time seedlings. When planting carrots, the principle of early seedlings and late seedlings should be used to ensure that the seedlings are all strong. The first seedling sown was carried out at the time of 2 true leaves with a plant spacing of 8 cm, and the second seedling was sown at an interval of 10 days with a plant spacing of 15 cm.

After 1 week of seedlings sown, the seedlings are separated, leaving 4 5 healthy seedlings, and the second seedlings are interspersed after breaking the white, so as to ensure that each hole has 1 strong seedling.

2) Cultivating and weeding. After the first seedling, loosen the soil and weed once. Seedlings, weeding, and cultivating can be combined to save labor.

3) Phased top dressing. The base fertilizer is sufficient, you can apply less top dressing, after breaking the white and the straight roots begin to swell each chase a thin fertilizer water, do not fertilizer concentration is too large or the fertilizer is too close to the roots, so as not to burn the roots.

4) Reasonable irrigation. Carrots need more water to grow, and they need to be supplied in a timely and appropriate amount, especially in the straight root expansion period, such as dry climate and lack of soil water, which will make the roots thin, rough, lignified, spicy, easy to hollow and reduce quality.

5) Disease prevention and insect treatment. During the growth period, the focus is on the prevention and control of aphids, cabbage insects, and yellow-striped jumping beetles. For the control of aphids, 10% aphid lice net 10g per mu can be sprayed with 50kg of water.

The control of cabbage worm and yellow striped jumping beetle can be treated with BT 300 times solution plus insecticidal double 500 times solution or 5% anti-Taibao 1500 times liquid spraying.

4. Harvesting. Generally, it can be harvested in batches 45 days after sowing, and the yield is low if it is harvested too early, and it is easy to hollow out and reduce the quality if it is too late.
