What are the key techniques for cultivating high-quality late rice after lily?
In 2003, Zeng Zhaozhu of Daping Village, Niangxi Town, Xinshao County planted 1.21 mu of lily, harvested 1150 kg of lily in this year's autumn harvest, and sold it for 4630 yuan. After the lily harvest, he planted high-quality late rice as a follow-up crop, and the late rice is expected to yield more than 500 kg per mu. Old Zeng said that in recent years the lily market has been good and high-quality rice is even less of a concern to sell. Adopting the lily - high-quality late rice model not only implements paddy-upland rotation, which benefits both the lily and the high-quality late rice, but also achieves a double harvest of money and grain.
After the late rice harvest, plant lily as soon as possible. Choose a sandy loam paddy field with relatively high terrain, good drainage, deep soil layer, and fertile, loose soil. After the late rice has headed and filled, open drainage ditches well. After the late rice is harvested, quickly deep-plow and prepare the land, and apply 50 kg of lime per mu for soil disinfection. Then divide into beds and open ditches; generally the bed width is 2.5 m, and the bed ditch is 25 cm wide and 30 cm deep. At the same time, open the main ditch and the surrounding ditch well; the main ditch and the ditch are 30 cm wide and 40-50 cm deep. Select Longya lily seeds with neat bulb roots and whiskers, tightly clasped scales, pure white color, and no pests, diseases, or rot, using 250-300 kg of seed per mu. Sow in mid-October. Before sowing, the lily seed bulbs must be disinfected, that is, spray the seed bulbs with 800-fold dilution of 50% carbendazim, let them sit for 30 minutes, and plant after drying. Draw sowing furrows at a row spacing of 30 cm, with a furrow depth of 13 cm, then plant at a hill spacing of 20 cm. Apply 2000-2500 kg of decomposed pig and cattle pen manure and 50 kg of 45% compound fertilizer per mu between two hills, without touching the seed bulbs. After planting, cover with a layer of fine soil, with a thickness 3 times the height of the seed bulbs. Level the bed surface, then cover with rice straw to prevent freezing and preserve moisture.
Strengthen field management of lily. Before the Start of Spring, when the lily has not yet emerged, apply 1000 kg of human excrement and urine per mu as a topdressing in combination with intertillage. When the seedlings are 20 cm high, apply 50 kg of decomposed cake fertilizer, 500 kg of human excrement and urine, and 10-15 kg of 45% compound fertilizer per mu. Pay attention to clearing ditches and draining water. In the first and middle ten days of June, spray the leaves 2-3 times with a mixed solution of 0.5% urea and 0.3% potassium dihydrogen phosphate, once every 5-7 days, and remove the flower buds. After emergence, use Bordeaux mixture at 1:1:120-150 times to control damping-off, gray mold, brown spot, and other diseases. At the same time, use 10% acetamiprid to control aphids. Harvest and dig in late July, and process promptly.
High-quality late rice cultivation. Select high-quality medium-maturing rice varieties or combinations such as Jinyou 207. Sow on June 20-22, with sparse and even sowing. At the 3-leaf stage, spray the seedlings evenly with 100 g of 15% paclobutrazol mixed with 50 kg of water per mu. After the lily is harvested, rush to transplant the late rice in season.
