1. Base fertilizer: 4000-5000 kg of farmyard manure and 50 kg of compound fertilizer (N:P:K=5:4:1) per mu of ginger field.
2. Three-pronged top dressing: acupuncture or ditch at a distance of 15 cm from the base of the seedling, apply 100 kg of compound fertilizer per mu of ginger field, and irrigate once to dissolve the fertilizer.
3, in the expansion period of topdressing: after the fall, each plant differentiated 6-8 forks, 50 kg of compound fertilizer per acre of ginger field, and pay attention to soil moisture. If it is dry, it will be irrigated every 4-6 days, and often cultivated to the base of the plant to promote the growth of its rhizome.
Through one base fertilizer and two top dressings, and the appropriate fertilizer N, P, K ratio, and the appropriate amount of application and irrigation, you can adjust the growth and nutrition of the aerial parts (leaves) and underground parts (mainly rhizomes) Assignment to achieve high yield targets.
Stainless Steel Pipe is a kind of hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in manufacturing mechanical parts and engineering structures. It is also used for furniture, kitchenware, etc. The hardness of stainless steel pipe is usually measured by Brinell, Rockwell and Vickers. Annealed stainless steel pipe with inner diameter of more than 6.0 mm and wall thickness of less than 13 mm. Production process of stainless steel seamless pipe A. round steel preparation; b. Heating; c. Hot rolling perforation; d. Cutting head; e. Pickling; f. Grinding; g. Lubrication; h. Cold rolling; i. Degreasing; j. Solution heat treatment; k. Straightening; l. Pipe cutting; m. Pickling; n. Finished product inspection. Common materials are 201, 304 and 316.ETC
According to the growth and development rules of ginger cultivation stage, different fertilization, irrigation methods and fertilization amount should be adopted for the intake of water and fertilizer in different periods. The fertilizer used for ginger can be divided into two types: base fertilizer and topdressing. According to chemical composition, it can also be divided into farmyard manure and fertilizer. Farmyard manure is generally only used as base fertilizer, and chemical fertilizer can be used as both base fertilizer and top dressing. In particular, it should be noted that when using chemical fertilizers, it is necessary to have an appropriate ratio of elements. Generally, the ratio of fertilizer should be such that the net content of the element is N:P:K=5:4:1. For the conditional use of ginger special compound fertilizer (N: P: K = 5: 4: 1). The fertilization of ginger can be applied in three periods, namely, base fertilizer, trigeminal top dressing and expansion period.
