Planting techniques of Lilium

I. planting scope

Lily varieties can be planted in the soil with a PH value of 5.2-7.8. If the soil is too acidic, 50 kg of lime powder is applied before ploughing, 50 kg of gypsum powder is used if the soil is too alkaline, ridges are formed after sticking the soil, and the sandy land is planted.

Second, base fertilizer: if it is not organic production, please refer to the following use of pharmaceutical fertilizer.

Fertilization before ploughing:

Formula 1, ammonium bicarbonate 50 kg, calcium superphosphate 50 kg and 50% potassium sulfate 15 kg: (when spreading fertilizer, sprinkle ammonium bicarbonate alone, then mix calcium superphosphate and potassium sulfate well before spreading.

Formula 2, ammonium bicarbonate 50 kg 45% (N15, P15, K15) potassium sulfate compound fertilizer 50 kg.

Formula 3, ammonium bicarbonate 50 kg, diammonium phosphate 50 kg, 50% potassium sulfate 20 kg. Choose one of the above three formulations according to the economic situation. Phoxim or other pesticides to control underground pests must be used per mu before ploughing and cultivated after evenly spreading. If there are conditions to apply rotten organic fertilizer, mix with phoxim particles and sprinkle, rake flat after ploughing.

3. Selection of species

The species are divided into one, two and three grades according to their size. After selection, they are soaked in carbendazim 600 times solution for 10 minutes to dry (must be dried).

IV. Planting

It can be planted from August to April of the following year (before June 1 in the northeast and northwest regions). 1. Ridging planting according to large row spacing of 50-60 cm, small row spacing of 15-20 cm, trenching depth of about 8 cm, after ditching according to plant spacing: primary seeds 14-16 cm, secondary seeds 10-12 cm, tertiary seeds 6-8 cm. There are 16000-22000 plants per mu under the forest and 22000-26000 plants in the field. (the big one is thinner, the smaller one is denser) after planting, the mature fermented soybean mixed with calcium superphosphate of 50 kg per mu can be applied between the seeds, (you can also not use or add compound fertilizer or mature bean cake, cottonseed cake, rapeseed cake, etc.) in the seed space. Then cover the soil 6-8 cm (the big ball is deeper and the smaller one is shallow). After completion, the soil can be watered along the ditch if the soil is not wet. After the soil is not sticky, 150 ml of herbicide can be sprayed per mu while the soil is wet. If planted in sandy land, it can be planted according to small row spacing of 15-20 cm and cover soil of 6-8 cm. 26000-30000 plants per mu. After the completion of watering (water is not too urgent, sprinkler irrigation is the best), after watering, the dry land is immediately sprayed with 120 ml per mu of field supplement (herbicide).

5. Topdressing

When the seedling height is 10 Mel 15 cm, urea 15 kg and 45% potassium sulfate compound fertilizer 50 kg per mu are mixed and used, and then 45% potassium sulfate compound fertilizer 50 kg plus 50% potassium sulfate 15 kg is applied in about 40 days. If you plant in a bed, you can also apply fertilizer with water. Apply 45% potassium sulfate compound fertilizer 50 kg after a month in rainy areas, or add 50% potassium sulfate 15 kg to mix well (at least 3 times in rainy areas).

VI. Blossoming

When the last layer of leaves has just grown buds, choose to blossom in a sunny day, spray carbendazim solution immediately after blooming, or add up to 2116 (foliar fertilizer) and 0.3% urea solution.

VII. Coverage

When the seedling height is 30-40 cm, spray Lesbon (alias Poison, Toxotick) 800 times on the root to prevent the tiger, spray again after a month. If there is wheat straw or rice straw and leaves cover only seedlings in the space, it can play the role of pressing grass, heat preservation, cooling and increasing soil organic matter.

VIII. Key points of management

1. The bottom is fat and nutritious.

2. During the germination period, the moisture should be sufficient, the soil should be kept moist during the growth process, and the drainage should be paid attention to to avoid stagnant water.

3. Topdressing aggravates nitrogen in the early stage, phosphorus and potassium in the middle stage, and potassium in the later stage.
