Winter Peony Day Lily High Yield

Day lily, also known as day lily flower, is a perennial root crop, and it will play an important role in seizing the high yield in the coming year. According to the planting experience of high-yield units, do a good job of winter cultivation, the following year lily growth rate of up to 20%.

After the removal of debris, the day lily was harvested and the dry leaves were removed timely, the old leaves were cut off, and the defoliation branches were collectively burned. A lime-sulfur agent of 0.6 Baume was sprayed on the residual piles. During the growth of winter seedlings, weeds should be removed. It is generally advisable to dig between 15 to 20 centimeters deep in the rows to loosen the soil and provide good ventilation. This will increase the natural fertility of the soil and promote the development of the root system. And select good weather spray a 40% Leko emulsion 1000 times, to reduce the wintering base of pests and bacteria, can significantly reduce the incidence of pests and diseases in the coming year.

The native soil is cultivated from the shortened stem segments, and has the characteristics of top-down, one-year-old, and hair roots moving up year by year. After entering the rich period, the root system of lily is very developed. If the soil is not cultivated in the soil, the root system will be exposed on the soil surface, which will greatly weaken the absorption function of the root and the drought resistance of the plant. Therefore, to seize the cultivation of earthworms in winter, one can protect the root system from damage caused by various external factors; the second is to thicken the surface layer of the car, expand the range of root activity, and enhance its nutrient absorption area, which is beneficial to The formation of strong seedlings; the third is to increase the temperature of the winter surface soil to prevent frost damage. The day-to-day lily cultivation will be quick, young, and strong in stress resistance in the coming year. The harvest period can be 5 to 7 days in advance. The cultivars generally start from the withering of the fall seedlings until the end of Osamu. Remove the withering autumn seedlings, spray a carbendazim fungicide, and then pick up more fertile pond mud, river mud, or earth miscellaneous fertilizers, etc., and plow it over the plants and spread them between rows to thicken the soil. Improve the garden. Before the spring sprouts germinate, the top soil of the plexus was scattered and the soil was planted around the soil. It is important to note that young plants should not be used for cultivating earthworms for daylilies so as not to affect the tillering power. However, they can be used to improve the soil between the rows. After the spring, combined with the first cultivator, the smashing and smashing of the fertilizer mud will facilitate the unearthing of the spring seedlings as soon as possible.

Winter fertilizer application of winter fertilizer should grasp the following technical points: First, the fertilization time to stop growing in the above-ground part of the lily, that is, after the autumn seedlings withered by frost is appropriate; second is mainly organic fertilizer, day lily After entering the winter, the absorption function of the root system is greatly weakened, and the nutrient decomposition of organic fertilizers is slow, which is conducive to the long-term absorption of the root system of the day lily, and reserves sufficient nutrients for the lily seedlings in the following year to lay a solid foundation for the high yield of day lily; The amount of fertilizer used should be determined according to the soil fertility and the type of fertilizer. In general, 1500-2000 kg of cow manure per mu, or 2000-2500 kg of heap manure, or 500-750 kg of human waste. At the same time with the appropriate amount of phosphorus, potassium fertilizer, generally per acre can apply 25 ~ 30 kg of calcium phosphate, potassium chloride 5 ~ 7.5 kg; Fourth, pay attention to fertilization method, should be between the day lily clusters or row spacing 10-13 cm Open a hole deep, hole width 17 ~ 20 cm, depth 13 ~ 17 cm, timely soil after application, to prevent loss of nutrients.

Ditching day lily is most afraid of water, and winter should also pay attention to drainage. According to the condition of soil waterlogging, the width and width of the ditch will be determined. The following rain will not be affected by water, and it will not wash away the daylily of the lily.
