High-yield cultivation techniques of Edible Lily

Lily is a cross-year crop. After planting in the autumn of the first year, it will not be able to break the soil and show seedlings until the following spring, during which it has been bred and grown in the ground for nearly half a year. In order to obtain high yield, the following technical links should be grasped in cultivation:

First, the selection of suitable improved varieties of lily is divided into edible and medicinal two categories, a total of more than 10 varieties. The quality of edible lily is the best. The variety has enlarged scales, shaped like dragon teeth, white and delicate, no bitterness, high price and good market. Medicinal lilies generally have short scales, low yield and bitter taste, so they can only be used as medicine. Therefore, when introducing edible lily species, we must choose seed balls with white color, large scales, no pockmarks and no bitterness. Lily has a low reproduction coefficient and a large amount of seed, and it needs about 150 to 200 kg of bulbs per mu.

Second, choose suitable soil lily to avoid continuous cropping or rotation with onion and garlic crops, and legume or Gramineae crops are better in the previous crop. Before planting, turn the soil more than 25 cm deep, apply 2500 to 3000 kg of rotten organic fertilizer and 25 kg of superphosphate as base fertilizer per mu, and turn 50% of Dianong into the soil at the same time to disinfect the soil. After fine raking, it is made into a high or flat bed, with a width of 2 meters and a depth of 30 centimeters.

Third, sowing lily seeds at the right time is the bulb of lilies, also known as bulbs. Lily seeds should be sowed in October. Before sowing, the bulbs are soaked in 2% formalin solution for 15 minutes, then taken out to dry and sowed. The row spacing is 25 cm, the plant spacing is 15 cm, and the depth is 10 cm. Cover with straw or leaves to keep moisture after sowing.

Fourth, after field management planting, seedlings will emerge in March next year, which can be ploughed one or two times, and the exposed lilies should be cultivated in time. When the former seedlings of the Beginning of Spring were not unearthed, re-apply fertilizer once, applying 1000 to 1500 kg of human urine per mu. Lily seedling emergence should not be deep ploughing and weeding, so as not to damage the root system. When the seedling height is 3 to 5 cm, cover the ground with about 500 kg of straw per mu. When the seedling height is 20 cm, apply one-time seedling fertilizer, 10-12 kg urea per mu and 7.5-10 kg potash fertilizer per mu. The height of the seedling is about 30 to 35 cm, topping and picking off the head in time, and concentrated nutrients are transported to the bulb. In the first ten days of July, 50 kg of water was sprayed with 10 packets of advanced compound fertilizer to prevent premature senility. Lily is afraid of waterlogging, so it is necessary to dredge the ditch system in time in rainy season and after heavy rain. Leaf spot and bulb rot can be sprayed with 65% mancozeb 500 times solution, once every 7 days, for 3 to 4 times. Aphids can be sprayed with 1000 times of dimethoate EC, and root maggots can be irrigated with 1000 trichlorfon.

5. The growing period of interplanting lilies is nearly one year, so it should be interplanted reasonably. In winter, radish and green vegetables can be interplanted; interplanting watermelon or potato in May next year will help to loosen the soil, reduce the harm of grubs and promote the expansion of lilies.

Sixth, after the timely harvest of the Beginning of Autumn, the lily stem turns yellow and withered, and the flowers fall off is the right time for harvest. At this time, the bulb is fully developed, the yield is high and resistant to storage. Harvesting should be carried out on a sunny day, and the bulbs should be dug out and cut off the ground, and immediately transported back to the room and buried in clean river sand for storage, so as to prevent discoloration and dryness, affecting economic benefits.
