[0008] Judging from the traditional planting habits and fertilization measures of the above three crops, the waste of light and heat resources and the multiple top dressing operations also caused a waste of labor. At the same time, due to the use of quick-acting fertilizers such as urea for fertilization, the nutrient conversion speed is faster, volatilization and leaching Severe, causing serious loss of nutrients and also causing fat loss
In addition, due to the large individual plants in the late stage of crop growth, it is not suitable for mechanized operations. Farmers often use the method of artificially spreading quick-acting nitrogen fertilizers into the ground combined with watering, which increases the risk of nitrogen leaching downwards, thereby affecting groundwater quality and reducing Nitrogen utilization rate, and some farmers simply do not topdress due to operational difficulties, resulting in decreased yield and lower income

Embodiment 1
[0032] Embodiment 1, planting plot is test field A
[0033] A kind of onion-ginger-wheat rotation production method that improves land productivity, two years as a cycle, the steps are as follows:
[0034] (1) On March 22 of the first year, 4500kg / mu of decomposed farmyard manure was spread, and deep plowing and sun-drying were carried out on April 5 of the first year; The width is 40cm, and the width of the ditch is 30cm. At the bottom of the ditch, the ginger seeds are planted along the direction of the ditch. The ginger buds are facing upwards, and the distance between the plants is 23cm. In the middle of the ginger ditch, draw a 5cm deep ditch and apply 65kg / mu of potassium sulfate compound fertilizer, which is equivalent to pure nitrogen. 6.5kg / mu, phosphorus is P 2 o 5 13kg / mu, potassium in K 2 O meter 9kg / mu, apply zinc sulfate 1.5kg / mu, borax 0.7kg / mu, calcium and magnesium fertilizer 4kg / mu, after fertilization, build a ditch in the middle of the two ginger rows, a...

[0039] A kind of onion-ginger-wheat rotation production method that improves land productivity, two years as a cycle, the steps are as follows:
[0040] (1) On March 24th of the first year, 5000kg / mu of decomposed farmyard manure was spread, and on April 7th of the first year, deep plowing was carried out; on April 10th of the first year, ginger was planted, the land was prepared, the furrows were adjusted, and the ridges were raised. The width is 40cm, and the width of the ditch is 30cm. Ginger seeds are planted along the direction of the ditch at the bottom of the ditch. The ginger buds face upward and the plant spacing is 22cm. In the middle of the ginger ditch, draw a 4cm deep ditch and apply 80kg / mu of potassium sulfate compound fertilizer, which is equivalent to pure nitrogen. 8kg / mu, phosphorus is P 2 o 5 Calculated at 15kg / mu, potassium is expressed as K 2 O meter 12kg / mu, apply zinc sulfate 1.8kg / ...

Abstract
The invention relates to a scallion, ginger and wheat rotation production method capable of improving the land production capacity. According to the method, ginger is planted in early April of the first year, wheat seeds are sowed in ginger channels in the middle of October or in late October, and ginger is harvested in late October; wheat is harvested in early June of the second year; then, in late June, land preparation is conducted for scallion planting and scallion is harvested in early December. According to the method, the three different crops of the ginger, the wheat and the scallion are planted in a rotation mode, the problem of soil successive cropping obstacle can be solved due to the influences of root exudate, and the soil continuous production capacity can be improved.
Description
technical field [0001] The invention relates to a method of crop planting production process, in particular to a production method of ginger, wheat and green onions in two-year, three-crop rotation, and belongs to the technical field of crop planting. Background technique [0002] Ginger is an annual cultivated vegetable. Due to the high yield per unit area and objective economic value of ginger, the area suitable for planting is expanding year by year, and the blind pursuit of high yield has greatly increased the input of chemical fertilizers. However, due to its characteristics, ginger should not be planted in consecutive years, and the obstacles to continuous cropping are very obvious. The serious increase in soil-borne diseases and the increase in the incidence of ginger blast will lead to a significant reduction or even extinction of ginger production in the coming year. However, in order to obtain higher economic value, farmers have to use ginger The same plot is plant...
