Cultivation and management of healthy vegetable lily

Lily is a perennial plant of Liliaceae. its underground bulb contains a lot of protein, fructose and pectin, which can be eaten fresh, starch can be extracted, canned or processed into dried lily and so on. Fresh stem has the effects of tonifying vital energy, nourishing yin and moistening lung and relieving cough and asthma. It is a popular new type of vegetable in the market and is loved by many citizens. The market price is more than 20 yuan per kilogram. The economic benefit of planting is considerable and the development prospect is broad.

Lily has wide adaptability to climate and soil and likes cool weather. The aboveground stem is not resistant to frost, drought and water. The optimum temperature for plant cultivation is 15-20 ℃. It is best to cultivate in sandy soil with deep soil layer and good drainage. Its bulb grows rapidly, its color is white, and its commercial performance is good.

First, apply basic fertilizer for land preparation

The planting land should choose sandy loam with good drainage and deep soil layer, not continuous cropping, in order to prevent the occurrence of blight, the soil layer should be turned over more than 20 cm, and enough rotten organic fertilizer should be applied.

2. Planting bulbs

Most lilies use asexual reproduction and grow into commercial bulbs 2-3 years after planting. Generally sowing seeds when the ground temperature is about 20 ℃. Before sowing, add copper sulfate and quicklime 0.5kg with 100kg water before sowing, and then soak the seed balls in solution for 10 hours for 20 hours to kill bacteria and promote rooting. The planting density is 30cm between rows and 20cm between plants. After planting the bulb, fill the fine soil around it, and then apply base fertilizer between the plants, so as to avoid direct contact between the fertilizer and the bulb, so as not to cause rotten seeds. Cover the soil after sowing and cover the bulb. To prevent frost damage and keep it moist, cover it with straw or other weeds.

III. Field management

After emergence, remove the straw, open trenches to chase fertilizer, fertilizer can not touch the bulb. After sprouting, only one of the strongest buds is left, and the rest of the buds are removed to prevent the bulbs from cracking. Melons or legume vegetables can be planted between rows to shade and cool lilies. Topdressing and ploughing was carried out when the seedling height was 20cm to 25cm, which promoted the growth of stems and leaves, and cultivated soil to protect the exposed scales. Enter the bulb expansion stage when budding, at this time apply a pile of compost organic fertilizer. In the later stage, 0.2% potassium dihydrogen phosphate and 0.1% urea were sprayed on the leaves to prolong the life of the functional leaves.

Topping is carried out when the plant height is about 50 cm, which can inhibit the growth of stems and leaves, promote bulb expansion, and remove the buds in time to reduce nutrient consumption. The ground should be covered with grass in high temperature in summer, reduce soil temperature and reduce water evaporation, irrigation once every 5-7 days during drought, furrow irrigation should be used to reduce soil consolidation. Drainage and waterlogging prevention after rain.

IV. Harvest

When the aboveground part of the plant is completely withered and the bulb is fully mature, not only the yield is high, but also the product is resistant to storage. generally, the yield per mu can reach more than 1000 kg.

Prevention and control of diseases and insect pests

The main diseases of lily are Rhizoctonia solanacearum and soft rot, which can be controlled by Pulike 1000 times and Carreton 800 times. The main pests are grubs, which can be controlled by root irrigation with BT emulsion or phoxim 1000 times.
