Problems solved by technology

[0005] Chinese patent document 201310533982.6 discloses a method of topdressing winter wheat after irrigation. This method is easy to implement in operation, but the ridges in the field are prone to collapse during irrigation, the water surface retention height is uncertain about the water volume, and the nitrogen fertilizer under different yield levels The amount of topdressing and the technical requirements under different soil conditions are debatable
This technology has also begun to be popularized and applied to winter wheat in rain-fed areas such as Hebei. Although it has obvious advantages in wheat crops, it also has certain disadvantages. It needs to lay pipes for water spraying and fertilization, and the investment in equipment is large. Compared with grain In terms of output income, many people are not easy to accept
In addition, the labor force currently staying in the countryside is either elderly people over the age of 50 or 60, or women, with low technical level and ability. Whether the nutrient concentration is appropriate, pipeline blockage, irrigation water limit, etc. are all technical links that need to be faced. , and located in rural areas, the safety of equipment such as pipelines and fertilization tanks is also a problem, so the implementation and promotion of integrated water and fertilizer applications are also limited by many factors
[0007] At present, there are a series of problems in spring irrigation of winter wheat: either it is practical but not water-saving and fertilizer-saving, or the technical method is advanced but difficult to operate and difficult to spread in a large area. It is unfavorable in many aspects such as serious waste

Embodiment 1

[0040] A winter wheat spring irrigation and fertilization method for drought resistance and water saving, the fertilization and irrigation are as follows:

[0041] 1. Apply nitrogen and potassium fertilizers at the early stage of wheat jointing, and then irrigate after fertilization, nutrient input dosage and application period:

[0042] The perennial yield of wheat is about 660kg / mu, the amount of nitrogen fertilizer input is 12kg / mu in terms of pure nitrogen, accounting for 63% of the total nitrogen input in the whole growth period of wheat, and the amount of potassium fertilizer is 3.6kg / mu in terms of pure potassium, which is the 45% of the total potassium input during the growth period,

[0043] The remaining nitrogen fertilizer (37% of the total nitrogen input during the entire growth period) and potassium fertilizer (55% of the total potassium input during the entire growth period) of wheat throughout the growth period are applied as base fertilizer at one time before w...

Embodiment 2

[0050] A winter wheat spring irrigation and fertilization method for drought resistance and water saving, the fertilization and irrigation are as follows:

[0051] 1. Apply nitrogen and potassium fertilizers during the rising period of spring wheat, and perform spring irrigation after fertilization, nutrient input dosage and application period:

[0052] The annual yield per mu of wheat is about 520kg / mu, and the amount of nitrogen fertilizer input in terms of pure nitrogen is 9kg / mu, accounting for 55% of the total nitrogen input in the whole growth period of wheat. The amount of potassium fertilizer applied in terms of pure potassium is 2.4kg / mu, which is the whole 40% of the total potassium input during the growth period,

[0053] The remaining nitrogen fertilizer (45% of the total nitrogen input during the entire growth period) and potassium fertilizer (60% of the total potassium input during the entire growth period) of wheat throughout the growth period are applied as bas...

Embodiment 3

[0060] A winter wheat spring irrigation and fertilization method for drought resistance and water saving, the fertilization and irrigation are as follows:

[0061] 1. Apply nitrogen and potassium fertilizers during the rising period of spring wheat, and perform spring irrigation after fertilization, nutrient input dosage and application period:

[0062] The annual yield per mu of wheat is about 450kg / mu, the amount of nitrogen fertilizer input is 6kg / mu in terms of pure nitrogen, accounting for 45% of the total nitrogen input in the whole growth period of wheat, and the amount of potassium fertilizer is 1.5kg / mu in terms of pure potassium, which is the whole 30% of the total potassium input during the growth period,

[0063] The remaining nitrogen fertilizer (55% of the total nitrogen input during the entire growth period) and potassium fertilizer (70% of the total potassium input during the entire growth period) of wheat during the whole growth period are applied as base fert...

Abstract

The invention relates to a drought-resisting and water-saving winter wheat spring irrigation and fertilization method. The drought-resisting and water-saving winter wheat spring irrigation and fertilization method is implemented in winter wheat regeneration and jointing stages. The method comprises the following steps of (1) applying nitrogenous fertilizer and potash fertilizer in wheat fields; (2) performing water irrigation through a simple micro-spraying device; (3) starting irrigation from the far end of the wheat fields, after water sprayed by micro-spraying hoses rests on the field surface for 3-5 minutes, removing a section of the micro-spraying hoses to irrigate other areas in sequence until reaching the other end of the fields, and ensuring the irrigation amount to be 35-40 m3 per mu (=0.0667 hectares). The drought-resisting and water-saving winter wheat spring irrigation and fertilization method achieves water irrigation through the simple micro-spraying device, and accordingly is low in cost, simple in installation and field operation, assures years of service, avoids risks of ageing and loss and facilitates water amount control and observation; meanwhile, the drought-resisting and water-saving winter wheat spring irrigation and fertilization method is easy to accept by farmers during production, and by matching fertilization with water irrigation, saves water consumption as well as input of nutrient of nitrogen, phosphorus and potassium, ensures the yield of wheat and improves the utilization rate of nitrogenous fertilizer.

Description

technical field [0001] The invention relates to a drought-resistant and water-saving winter wheat spring fertilization method, which belongs to the technical field of crop cultivation. Background technique [0002] Wheat is one of the main food crops in my country, and it is planted all over the country. Wheat mainly includes winter wheat and spring wheat, among which winter wheat accounts for more than 90% of the total wheat planting area in my country, and its area and total output are in a dominant position. Winter wheat has a long growth period, which takes 230-240 days from sowing to harvest. During such a long growth period, wheat growth is affected by variety characteristics, climatic conditions, soil conditions, fertilizer types and amounts, irrigation methods, and pests and weeds. significantly, water and fertilizer are the main factors affecting the stability or increase of winter wheat yield in recent years. [0003] In the winter wheat area in the Huanghuai are...
