Precocious farmland can be harvested from the end of June to the end of July. At this time, the market is in short supply, and the price is twice as high as in the autumn. The economic benefits are good and it is worth promoting. Its high-yielding cultivation techniques are now described as follows: 1. Use good breeds and mine at the right time. The commonly used early-maturing lotus seed varieties include Hubei "June Report", "201", "202", "203", and "Jiangsu Huarong". It was mined 3 to 4 days before transplanting, and it was about the end of March. For every 667 square meters (1 mu), the amount of 250-400 kg is used. 2. Choose Haotian. In order to use the paddy field, we must select paddy fields that have water all year round and are not affected by drought and have a depth of 0.5 meters. 3. Deeply change the soil and reapply basal fertilizer. Winter fields should be turned over for the winter and re-applied basic fertilizers. They can use 667 square meters of chicken manure 1,000 kilograms or pig cow dung 2500 kilograms. If there is a biogas fertilizer, 667 square meters of biogas fertilizer will generally require 10-15 tons of biogas fertilizer. Through ploughing, the base fertilizer and the soil in the field are evenly mixed, so that the thickness of the mixed fertilizer is 15 cm. Rhizome is a rhizome crop. There are too many top dressings during the growth period, and it is difficult for crops to absorb completely, so the base fertilizer should account for about 90% of the total amount of fertilizer. Perennial Putian, every 3 to 4 years to carry out rotation. 4. Timely planting and reasonable close planting. Planted in early April, the plant spacing is 1.2 meters 2 meters or 1 meter 1.5 meters, rough and sparse planting. Planting is generally carried out by slanting cultivation. The specific method is to dig a ditch of about 15 centimeters and place the species in the ditch. The hoe head is down and the mud surface is 8 centimeters long. The direction of the rake is the same. The direction of the line is opposite. 5. Strengthen field management (1) Appropriate top-dressing: In the middle of April, Tajiri began to pump leaves, and weeding in combination with seedlings in Putian, we can apply 10 kg of urea at 667 square meters. In the middle and mid-May, we applied swelling fertilizer, and the leaves began to seal. , 667 square meters topdressing compound fertilizer 25 kilograms to prevent morning dew fertilization. (2) Staged water control: Shallow water promotes branching in the bud stage, promotes early emergence of leaves, and generally has a water depth of 5 to 10 centimeters to prevent water cut-off; the water depth of stems and leaves during the growth period is 20 centimeters; (3) Timely weeding: After weeding the leaves, the weeds are removed in time, mainly for the artificial field and weeding. (4) Control of pests: mainly aphids, Spodoptera litura, and rootworm. (5) Store good species: The species must be stored in the field until the end of March of the following year. The species should not be washed to prevent loss of water and skin discoloration.
