Early spring management of planting leek in greenhouse
First, temperature management. Leek likes to be cold and cool, and the suitable temperature for growth is 15 mi 24 degrees, which should be kept out properly during the day. In order to promote sprouting, the daytime room temperature should be kept at 18 Mel 25 degrees after the buckle shed and at 17 Mel 23 degrees after sprouting. Before the Chinese chive is harvested, the daytime temperature is 15 ~ 22 degrees, and the night temperature is 10 ~ 12 degrees. In the future, the temperature of each cut can be increased by 2mi 3 degrees, but not more than 30 degrees.
Second, fertilizer and water management. The growth of leek requires lower air humidity and higher soil moisture. The greenhouse air humidity is maintained at 60-70%, and the absolute soil water content is maintained at 13-15%. In general, heavy soil will no longer be watered if it is watered for the winter before buckling the shed. In order to promote the growth of Chinese chives, one small amount of water can be poured 7 days before the first knife harvest, and 15 kilograms of ammonium nitrate should be hydrated and applied with water every 667 square meters (mu), and then water and fertilizer should be applied 7 days before each leek harvest.
Third, foliar fertilization. During the growth period, potassium dihydrogen phosphate is sprayed every 7 days with a concentration of 300 times, and gibberellin can also be used with a concentration of about 40,000 times. When it grows to 15 cm, spray 1 gram per 667 square meters, add 50 kg of water, and then add 0.5% ammonium nitrate for better effect. Fourth, harvest. The harvest period is generally in New Year's Day or before the Spring Festival, the cut with yellow is more appropriate, the interval between the two leeks is about 35 days.

Management method of planting Toona sinensis in greenhouse
Toona sinensis belongs to woody vegetables and its tender leaves are edible. When the ten-day average temperature is 15 ℃, the buds begin to sprout and show new leaves. Therefore, the picking period of open-field Toona sinensis in the middle of our province is mid-April. The greenhouse production of Toona sinensis is to transfer the stems of deciduous 1-and 2-year-old Toona sinensis into

Cultivation of Dictyophora by soybean shading
The original cultivation of Dictyophora uses bamboo shavings as raw materials, and the cultivation yield is low (20ml 30kg / mu). Since 2000, the country has pioneered to use grain husks as raw materials to cultivate and build shade sheds. The yield per mu has been increased to 120kg per mu, and the benefit has been increased by 4 times. Soybean has been used for sunshade cultivation since 2001.
