In recent years, carrots have become the main vegetable varieties for export, and with the expansion of planting area, the emergence of various crops has not become the main factor restricting the high yield of carrots. Through the experience of cultivation and management in recent years, we learned that in order to make Miao Miao Qi Miao, we must grasp the following measures. 1, fine soil preparation Fertilizer base fertilizer planted carrots to choose rich in organic matter, soil deep and soft, well-drained sandy loam, soil plowing depth is generally 25-30 cm. Applying basic fertilizer before ploughing, generally spread 3,000-4,000 kg of organic fertilizer per 667 square meters, about 75 kg of carrot-specific fertilizer, 2-3 times of ploughing after cultivating, making the soil finely crushed, without waste, and then turning the land into a wide one. Hey, perform drills. Generally 2 meters wide, broadcast 5 lines. 2. Careful selection and seed selection should pay special attention to selecting seeds that are full, mature and germinating, and use light seeds that have been dehaired as much as possible. Do a good germination test to determine the appropriate seeding rate. 3. Seed treatment When sowing, the bristles on the seeds are rubbed off, the seeds are immersed in warm water at 40° C. for 2 hours, and then they are taken out at an air temperature of 20-25° C. to maintain the appropriate humidity, turning once every few hours. Less than 10% seed germination when seed germs are exposed. 4, sowing and keeping carrots spring sowing is generally in mid-February, autumn sowing in mid-July. The seed to be treated will be planted in shallow grooves to sow the seed along the ditch. The cover soil should not be too thick, generally not more than 1 cm, and be repressed. After sowing, it should be irrigated immediately. Before the emergence, the soil should be kept wet and dry to ensure timely emergence. . Spring sowing should be covered with plastic film, that is, heat preservation and moisturizing, autumn seeding best cover the amount of wheat straw in the cover, that is to protect the earth after the rain and protect the seedlings Miao Miao whole. 5. Control of underground pests and chemical weed control. In order to prevent underground pests from biting the seedlings, 0.5 kg/667 square meters of phoxim and 30 kg of fine soil are sprinkled in the lotus root after the whole planting, and then the fine-tunneling is repeated. sowing. 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. Every 667 square meters with "Shi Tian fill" EC 100-150 ml 30 kg of water evenly sprayed the ground, can play a role in clearing the ground. 6. Seedling management is a critical period of management before carrot cotyledon is exposed to the ground and leaves are exposed. In particular, autumn sowing carrots are prone to dry and hot soil and cause seedlings to sprout, which causes seedlings to become bee-waisted and die. Special attention must be paid to Keep the soil moist to preserve seedlings. Dingmin Pharmaceutical supply Alogliptin API and Alogliptin Intermediates with high purity and best price.
