Zhao Xicheng has been engaged in greenhouse cultivation of cut flowers since 1996. He said that if you want to spend a lot of lilies, you must first choose a large flower bulb with a circumference of 14 to 16 centimeters. The cost of each kind of flower ball is about 1.8 yuan, about 12,000 grains per mu, and the cost is more than 20,000 yuan. A shed can produce more than 10,000 branches of oriental lilies, and the purchase price of each lily (10 flowers) is 30? Between 40 yuan. In this way, the cost of flower bulbs, fertilizers, and other expenses will be eliminated, and the net income of a shed will be nearly 10,000 yuan.
According to Lao Zhao, the key to planting long lilies is to control the temperature. Lily flowers need different temperatures at various stages. The optimum temperature from sowing to lily emergence is 10°C. The daytime temperature during lily growth is controlled between 12°C and 25°C. Otherwise, the Oriental Lily's flower buds are small, the stems are thin, and the quality cannot be guaranteed. The price will be affected.
In the high temperature season, in order to cool down, Lao Zhao really thought a lot of tricks. According to reports, in the first 10 days of planting flower bulbs, it is necessary to reduce the temperature inside the greenhouse through shade nets outside the plastic greenhouse. After planting the bulbs in the ground, a layer of straw shall be laid on top of them, and no straw may be covered with a shade net to prevent direct sunlight from reaching the ground, thus lowering the temperature of the ground. Lao Zhao also used a micro-sprayer, which was bought for a few hundred dollars, to spray water into the shed. The cooling effect was also very obvious. In this way, the temperature in the greenhouse can be controlled at 15-20°C, and the single-branch flowerhead can be guaranteed at 2-3, which greatly improves Lily's grade.
Zhao Xicheng also has a hand in controlling lily pests. Lao Zhao said that when the soil is to be soiled, insecticides such as nitrochlorobenzene and bacterin must be sprayed into the soil, and the amount of pesticide used is twice as much as in the fall. Insecticides should be given every 7 days after emergence to ensure the quality of the lily market.
Temperature control is good for many lily heads
In Wuwu Village, Xinchengzi Township, Xinchengzi District, Shenyang City, Oriental lily planted by the villager Zhao Xicheng has not yet been listed and has already been ordered out. The brokers who came to buy all said that the lily of the old species is of good quality and has a lot of flowers. His flowers can be sold at high prices, so that he can make a profit.
