The cilantro is commonly known as savory vegetables and oysters. The cool weather is not resistant to high temperatures and stops growing when the temperature exceeds 30°C. It is more difficult to plant, so growing parsley in summer will greatly increase economic benefits.
1. Variety selection Choose heat resistant, late bolting, fast growing varieties, such as Beijing parsley, North China leaf, and so on.
2. Soil fertility selection soil fertility, water retention and fertilizer performance, can discharge irrigation, permeability is good, more than five years have not been planted parsley soil land, must not be re-open, Mushi rot of farmyard fertilizer 4000 kg, cake fertilizer 100 kg. The former crop residues should be cleared to reduce the occurrence of pests and diseases. Deep plowing to make 畦 畦, 畦 wide 1-1.5 meters.
3. Immersion seed germination summer planting parsley seeding period is not strict, generally 5-6 months sowing, 40-50 days after sowing harvest. Immerse germination before sowing. Therefore, when the temperature is high, soil water content is low, and evaporation is rapid, and germination and sowing can ensure emergence of seedlings and rapid emergence. The method of germination is: soak seeds for 24-30 hours with clean water, remove them and put them on moist and non-polluting sacks, thickness 2-3 cm, and cover the wet sacks to keep the temperature at 20-25°C. - 2 times, keep the seeds with a certain amount of moisture, and germination after 3-4 days.
4. It is better to sow seedlings in the summer to plant the coriander seedlings. After spreading, the seedlings can cover the entire surface of the car, reduce the evaporation of water, and lower the surface temperature. The method of broadcasting is: firstly play the hatchback and keep one compartment, and take the cover soil reserved for the first sowing room on the sides of the two sides. Then fill the water, until the water penetrates evenly after sowing, cover the soil 1-2 cm after sowing, and then broadcast the empty car, the same method with the first broadcast. The amount of 2 kg per mu is used. After all broadcasts, perform a light pressure protection. If the weather is dry and the seedlings are affected, small furrow irrigation can be carried out.
5. The field management seedling height 4-5 cm when the seedlings weeding, seedlings from 2-4 cm, after the seedlings combined with irrigation Mushi a thin manure, the seedling height 7-8 cm when the first top dressing, this time the amount of fertilizer should be large , Mu topdressing ammonium sulfate 20-30 kg. The soil should be kept moist. Generally, water should be poured for 4-5 days depending on the weather conditions, and strict shading should be adopted. Strict shading is an important technical measure for the cultivation of parsley in the summer. Summer coriander harvest time is not strict, can be combined with sparse seedlings harvested in batches.
