Autumn parsleyThe suitable sowing period is from early September to early October each year, when the temperature is stable between August and 22, which is just rightCorianderOptimal conditions for growth. Due toCorianderCool-loving and cold-tolerant, it can tolerate temperatures as low as minus 5, so planting in autumn is guaranteedCoriandernormal growth.
In order to make thatAutumn parsleySeeds emerge as soon as possible and grow vigorously, we need to pay attention to the following points:
1.Temperature control:CorianderThe temperature requirements are strict, and too high or too low temperatures will resultCorianderof growth restriction. In the case of high temperatures, you can choose to interplant with tall crops orShade nettingto shade, forCorianderCreate a suitable environment for growth.
2.Seed treatment:CorianderThe seed shell is hard, and direct sowing will lead to slow emergence and low emergence rate. Therefore, before sowing, the seeds need to be cracked, and the seeds can be placed on the hard floor or crushed with beer bottles to divide the seed shell into two halves to improve the emergence rate.
3.Seed germination: In order to further improveCorianderThe speed of seed emergence can be used for seed germination. will be broken after the shellCorianderPlace the seeds on a damp paper towel and useplastic wrapCover and refrigerate for 24 hours to break the dormancy mechanism of the seeds. Then take out the seeds, put them indoors until the seeds are white, moisten the paper towel, and wait for the seeds to be white, and then you can sow the seeds.
4.Soil preparation: Choose soil that is loose, rich in organic matter and has good water and fertilizer retention capacity for plantingCoriander。The soil is first raked and finely leveled, and then applied to the fully decomposedFarmyard manureand a small amountTernary compound fertilizerAs a base fertilizer, water thoroughly after the soil is prepared.
5.Seeding Method: WillCorianderThe seeds are scattered on the surface of the soil, and then the topsoil is gently raked with a gripper. At the time of sowing, the seedlings can be eaten appropriately, so that it can be extendedCorianderof the harvest period.
6.Water and fertilizer management: At the seedling stage, a small amount can be topdressedUreaAs a seedling fertilizer. WhenCorianderWhen it grows to a height of 10 cm and enters the peak growth period, it is necessary to keep the soil moist and apply an appropriate amount of itUreato promoteCorianderof growth.

7.Prevention and controlPests and diseasesCorianderIt rarely occurs during the growing seasonPests and diseases, but may suffer from sclerotinia sclerotiorum. Sclerotinia sclerotinia is the main hazardCorianderAt the beginning of the disease, the base of the stem will appear water-soaked rot, and the affected part will appear white hyphae. The way to prevent sclerotinia is to uproot diseased plants in time under high humidity to prevent the spread of the disease.
PlantingCorianderIt is necessary to pay attention to the right sowing time and good planting methods. In autumn, especially from early September to early October, it is plantedAutumn parsleyThe best time to do it. temperature pairsCorianderThe growth of the can have a big impact, and temperatures that are too high or too low can affect themCorianderEmergence speed and growth. Therefore, it is necessary to choose appropriate shading measures or intercropping tall crops, forCorianderCreate the right temperature environment.
In addition, the treatment of the seeds is also an influenceCorianderplanting effectCriticalOne of the factors. RightCorianderSeed shelling treatment and germination treatment can improve the seedling emergence rate and growth rate of seeds. The selection and preparation of soil is also very important, to choose loose, rich in organic matter and strong water and fertilizer retention ability of the soil, in the fertilization should pay attention to the base fertilizer andTop dressingThe rational collocation.
Water and fertilizer management is also plantingCorianderThe important links should be carried out in a timely manner according to the needs of the growth periodTop dressing, and pay attention to the foliageTop dressingto improveCorianderyield and quality. in the prevention and controlPests and diseasesIn addition, it is necessary to pay attention to the prevention and control of sclerotinia sclerotinia and uproot diseased plants in time to avoid the spread of diseases.
To sum up, plantingCorianderofCriticalIt is to choose the right sowing time and adopt a reasonable planting method. Autumn parsleyThe best time to plant is from early September to early October, when the temperature is relatively stable and suitableCorianderof growth. When planting, pay attention to the following aspects:
1.Temperature control:CorianderThe suitable growth temperature is 15 20 °C, too high or too low a temperature will affect its growth rate and growth. It can be used when the temperature is too highShade nettingCarry out shade, or select and intercrop tall crops in order toCorianderCreate a suitable environment for growth.
2.Seed treatment:CorianderThe hard shell of the seeds is relatively hard, and direct sowing can easily lead to slow emergence or low emergence rate. In order to improve the germination rate of seeds, the seeds can be broken first, and the seeds can be placed on a hard floor and crushed with feet or tools to divide the seed shell into two halves.
3.Sowing method: Choose soil with loose soil, rich in organic matter, and strong water and fertilizer retention ability for planting. Before sowing, the soil is raked and leveled and applied to the rotten onesFarmyard manureand in moderationCompound fertilizeras a base fertilizer. Scatter the seeds on the soil surface, gently rake the topsoil, and keep the soil moist.
4.Water and fertilizer management: seedling stageCorianderThe growth is slower and a small amount can be topdressedUreaAs a seedling fertilizer. WhenCorianderWhen it grows to a height of 10 cm, it enters the peak growth period, and it is necessary to keep the soil moist and apply it appropriatelyUreato promote growth. In addition, it can also be at:Coriander20 days before harvesting, use 05%.UreaThe solution is sprayed with a foliar spray, which is sprayed every 7 days, which can be improvedCorianderyield and quality.
5.Prevention and controlPests and diseasesCorianderIt is rarely affected during the growing seasonPests and diseasesbut may be attacked by some diseases. ForPests and diseasesSome preventive measures can be taken, such as regularly clearing weeds in the field to avoid the spread of diseases; Detect and treat the affected plants in time to avoid the spread of the disease; Fertilize regularly to keep the plantHealthgrows, strengthens its resistancePests and diseasescapacity.
To sum up, plantingCorianderThe best time to plant is from early September to early October each year, and attention should be paid to temperature control, seed treatment, sowing methods, water and fertilizer managementPests and diseasesprevention and other points to ensureCorianderof normal growth and high yield.
