How to plant lilies to increase yield

Lily, scientific name (Lilium brownii var. Viridulum Baker), also known as Qiangshu, Mussel, Shandan, inverted Immortal, Chongmai, Atrium, Moro, heavy Box, Zhongfeng Flower, Lily garlic, Dafu garlic, garlic brain Potato, Night Lilium, etc., is a perennial herbaceous bulbous plant of the genus Liliaceae (scientific name: Lilium), native to China, mainly distributed in eastern Asia, Europe, North America and other temperate regions of the Northern Hemisphere. In recent years, there are many new varieties produced by artificial hybridization, such as Asian lily, perfume lily, fire lily and so on. The bulb is rich in starch, edible and used as medicine.

1. Chemical control method. When the lily seedlings grow to 18 cm high, chemical control is carried out: the lily plants are evenly sprayed with paclobutrazol 20g / mu, 10g / mu, 10g / mu, 5g / mu, 10g / mu, 5g / mu and 50kg / mu. It can make the lily stalk stout, enhance the ability of stress resistance and promote the formation and growth of bulbs.

two。 The method of picking buds and promoting stems. In addition to planting land, the buds should be cut off in time to concentrate nutrients on bulb growth in May-June, which is beneficial to yield increase.

3. The alum pouring method. In early February, 3000 grams of potassium alum or ammonium alum per mu were used before the lily seedlings were unearthed, diluted 1000 times and then poured, and re-applied every 7 to 10 days in Rain Water years. In this way, the differentiation and expansion of lily bulbs can be promoted, and the yield can be increased by 10% and 40%. It is noted that the effect of applying potassium alum is significant in potassium deficient soil and ammonium alum is better in nitrogen deficient soil.

4. Apply the method of micro-fertilizer. During the growth of lily, foliar micro-fertilizers rich in many trace elements, such as green Fenwei and Songgang Lvsheng, were sprayed to provide a variety of trace elements for lily growth, which could make lily plant strong, stress resistance enhanced, bulb growth and development good, and the effect of increasing yield and income was remarkable.
