I. Planting and Management

(1) Excrement: The planting density of alfalfa differs depending on the soil, species, seed size, and time of market. Generally, early-maturing varieties are denser than late-maturing varieties, and Tianshui is denser than Tanggu. In the morning, the city eats tender food more densely than the evening market, and the younger plants are planted with small branches rather than whole plants. The general row spacing is: 1.3 to 1.5 Ã— 1 m for early and mid-maturing varieties and 2 m Ã— 1 m for late-maturing varieties. Seeds of 1 to 3 pods per hole. Planting methods: The seedlings shall be discharged to the field in accordance with the required spacing and the whip, and then the steamed bread shall be buried in the mud for 10 to 13 centimeters. The rear section will be slightly inclined upwards, forming a 30 degree angle with the soil surface, so that the soil is close to the soil. Easy to accept sunlight, increase temperature, and promote germination. When planting, it is also necessary to pay attention to the direction of the species of apex buds, otherwise it will cause uneven distribution of lotus whip. The tip of the lateral whip, which is densely distributed, often dies, and does not scab and reduce yield. A variety of methods can be adopted for the orientation of this type of bulbous bud. For example, the ridges can be directed toward the centerline of the field on both sides so that they can grow neatly and can be harvested in the future. However, regardless of the style of row, the principle of Shantou is not to face Tianbian or outside the pond, so as to avoid the whip or scorpion crossing the field.

(2) Water level management: Different growth stages of lotus root have different requirements for the field water layer, generally from shallow to deep, and then from deep to shallow. Generally, 3 to 5 cm deep after planting; 7 cm deep when floating leaves appear; about 10 cm when 2 to 3 leaves appear; and then gradually deepen the water layer with vigorous growth of vertical leaves and branches. To about 15 centimeters. From the end of the harvest period to the month before harvest, shallow water levels should be put in place to promote scab. In addition, it should be noted that in the summer when typhoon storms cause the water level to soar, it is necessary to try to reduce the water level in time to avoid overwhelming the leaves, otherwise the plants will die or cause a reduction in production. Regardless of whether the typhoon or the Tanggu, the typhoon should be deeply flooded to prevent the wind from blowing off the petioles, and the typhoon would immediately drain the water to maintain the original water level.

(3) Dressing: On the basis of applying basal fertilizer, two top dressings are generally carried out. The first time it takes 6 to 7 pieces of lotus leaf to grow, it is in the period of vigorous growth, and the second time it is in the beginning stage of scab, it is applied. Reel fertilizer. For each 667 square meters (1 acre), the amount of topdressing is 2000-2,500 kilograms of human fecal urine. The top dressing method is to put shallow water first, and then use a manure bucket to drain into the middle of the field and fall. After 2 to 3 days, apply it to the field and mix it. Then put it again. Water is added to the original water level. Fertilizers should be rinsed with water immediately if they have fertilizer on their leaves.

(4) Cultivating weeds, picking leaves, and picking flowers: Generally, weeding in paddy field will begin around 2 weeks after planting, ranging from 2 to 3 times, and as many as 7 to 8 times. Until the line was closed, it began to scab, and it was no longer reckless. Putada water should be drained before Putian, and then the paddy fields should be placed on both sides of the leaf roll to avoid damaging the underground shoot tip. When Putian is to remove dry leaves in time, remove weeds, so that sunlight penetrates into the water to increase soil temperature, combined with topdressing. When buds occur, the peduncles are twisted above the surface of the water to avoid flowering and seedlings and consume nutrients.

(5) Turn tip: It adjusts the direction of the lotus whip. At the time of planting, attention has been paid to the direction of the terminal bud, but when the underground stem begins to divide the lateral whip, it is still necessary to adjust the direction at any time to evenly distribute the steamed bread and prevent it from entering the field. Generally, when the plant enters vigorous growth, the lianbian is also rapidly growing. When growing, when the leaf is found to be 0.7 to 1 meter long near the edge of the field, it is necessary to promptly transfer the underground tip to the field to prevent it from passing through the field. The shoots are very tender, easy to break, and should be done when the leaves and leaves are soft at noon. Care should be taken in turning the tip, first digging the mud inside the tip of the tip, then lifting the tip of the tip together and lifting it into the inside, then cover the soil. Generally 2 to 3 days to 1 time, a total of 5 to 6 times.

Second, harvest

When the leaves of the plant's base begin to yellow and the leaves of the terminal leaves turn reddish, the pods have matured. Harvest old mature pods, drain the water about 10 days before digging, remove the lotus leaf, and dig the hoe with a shovel; if most of the leaves are harvested, green pods will be harvested because the pods are easy to cut off, generally not Drain the water and dig it by hand. The depth and location of the radon were deduced from the distance and orientation of the terminating leaf and the posterior leaf. Farther away, the hoe is buried deeper, and the opposite is shallower. The rear ridge leaves and the terminating leaves lie just below the straight line.

For every 667 square meters (1 mu) of production, about 1000 kg of tender pods will be harvested in advance, and 1500-2,500 kg of old mature pods will be harvested. After the lotus root is harvested, it should be washed in the clean river and it must not be washed in the sewage.
