The demonstration site is located in Dayin Village, Huanglou Town, Qingzhou City, Weifang City, Shandong Province. The crop ginger is planted. The cultivation method is mother ginger (stem) planting. The demonstration area is 1 mu. The grower Meng Shouzhong planted on April 1. The client is a local farmer with more than 20 years of planting experience. Ginger is one of the main local crops, with extremely high market influence and planting value. Qingzhou City is located in the warm temperate semi-humid monsoon climate zone, with a mild climate and four distinct seasons. It is cold and dry in winter, hot and rainy in summer, and moderately warm in spring and autumn.

Specific fertilization program description.

Table 1 Fertilization schemes of two different treatments
project	Fertilizer name and application rate (mu)
	Fertilizer name and application rate	top dressing	Application method
demonstration field	Yuantaifeng active organic fertilizer 160 catties	20 catties of root	Base fertilizer: spread Topdressing: apply with water
	Organic fertilizer 200 catties
	150 catties of soybeans	Fertilize 20 catties
	17-5-28 compound fertilizer 300 catties
control field	Organic fertilizer 200 catties	Fertilize 20 catties	Base fertilizer: spread Topdressing: apply with water

Sampling method: random sampling method

Sampling point: (take 2 demonstration points, measure 2 meters at each point for sampling.)

Calculation method: (4.5 plants/m, row spacing 70cm, about 953m/mu, 20% soil)

 

Table 2 Comparison of agronomic characters

deal with	Stem thickness  (mm)	number of branches	Fresh weight  (catties)	Leaf thickness  (mm)	SPAD value	Leaf Nitrogen Content
demonstration	18.23	18	5	0.28	37.4	14.9
control	17.56	15	4.8	0.26	36.2	13.7

 

According to the analysis in Table 2, it can be seen that the diameter of the stem in the demonstration area increased by 3.8% and the fresh weight increased by 3.8% compared with the control field.

4.1%, leaf thickness increased by 7.6%, chlorophyll content increased by 3.3%, nitrogen content increased by 8.7%

Table 3 Comparison of production measurement data

Four, processing	line spacing  (cm)	Plant distance  (cm)	Community area (㎡)	Density  (plant/mu)	Community yield  (catties)	Average (catties)		Yield  (catties/mu)	Increase  (%)
						1	2
demonstration	70	22	1.4	4288	43.2	37.6	40.4	15400	22.4
control	70	22	1.4	4288	32.74	33.26	33	12577

According to the yield measurement results of the ginger demonstration field, the overall yield per mu of the demonstration field is higher than that of the control, which brings advantages in yield. Compared with the control field, the yield increased by 2823 catties, an increase of 22.4%. According to the purchase price of 0.5 yuan/catties at that time, the total income increased by 1411.5 yuan. w
