Spring carrot high yield points
At present, the emergence of malaria has not been the main factor restricting the high yield of spring carrots. To make Miao Miao Qi Qi, we must do a good job of the following measures: Fine sizing of base fertilizer. To grow carrots, we must choose rich organic matter. The soil is deep and soft, and well-drained sandy loam soil. The soil plowing depth is generally 25 cm to 30 cm. Applying basic fertilizer before ploughing, usually 3,000 to 4,000 kilograms per hectare of organic fertilizer, about 75 kilograms of special fertilizer for carrots, and 2 to 3 times of fine tillage after cultivating, so that the soil is finely crushed and no waste is added. Hey, perform drills. Generally 2 meters wide, broadcast 5 lines. Carefully selected. Selecting seeds should pay attention to the selection of full, mature and high seed germination rate, and try to use hair removal hair removal treatment, germination rate test to determine the appropriate seeding rate. Seed treatment. When the seeds are sown, the bristles on the seeds are rubbed off, and the seeds are immersed in warm water at 40° C. for 2 hours, then taken out at a temperature of 20 to 25 degrees Celsius, maintained at an appropriate humidity, and turned once every several hours, until there is more than 10%. The seeds germinate when the seed coat is exposed. Sowing and security. The spring sowing of carrots is generally from the end of February to the beginning of March. The treated seeds will be planted in shallow grooves along the ditch. The cover soil will generally not exceed 1 cm in diameter and be repressed. After sowing, the soil shall be soaked with water. Before the emergence, the soil shall be kept wet and dry to ensure timely emergence. Spring sowing should be covered with plastic film, which is both thermal and moisturizing. Prevention of underground pests and chemical weed control. In order to prevent underground pests from biting the seedlings, 0.5 kg of phoxim and 50 kg of fine soil shall be sprinkled in the lotus root after each mulch, and then sown in the trenches. Germination of carrots at the seedling stage is a key measure. In order to prevent the artificial seedlings from causing weeding, it is timely to apply chemical herbicides after sowing. Each acre with "Shi Tianbu" EC 100 ml ~ 150 ml of water evenly sprayed on the ground 30 kg, can play a role in cleaning the ground. Seedling period management. It is also a crucial period of management before the cotyledons of the carrots are exposed to the ground until the leaves are exposed. Special care must be taken to keep the soil moist to preserve the seedlings.
