I. Pay attention to the close contrast tests conducted by the crop plantation line to foreign countries who have conducted different cultivations of wheat. The results show that the output of the east-west line can be increased by more than 10 kilograms per mu. According to the analysis, the east-west direction not only helps to increase the light energy utilization rate of the crop, but also promotes the extension of the crop root group to the rows under the influence of the earth's magnetic force, thereby increasing its absorption and utilization of soil nutrients. According to further research, when arranging the planting direction of crops, the influence of monsoon wind direction should also be taken into consideration. It is proposed that on droughty soils, or in seasons with scarce rain, planting against the wind (vertical direction and wind direction) should be selected. It is beneficial to the maintenance of soil moisture and reduce the adverse effects of drought on crops. In the case of abundant water sources, or in high temperature and rainy season, it is advisable to select the wind direction, that is, the direction and direction are parallel to the cultivation, which is conducive to the adjustment of soil temperature and humidity, and the microclimate in the field. Improve and promote the normal growth and development of the crop.

Second, to regulate the control of light sowing or planting crops, in ensuring a certain density requirements, appropriate relaxation line spacing, give full play to the "border advantage" of crop reproduction; or to some crops (if, tea, etc.) to take pruning, pruning measures, In order to improve the ventilation and light transmission conditions among the groups of plants, they can effectively increase the effective utilization of light energy by crops and achieve the purpose of increasing production and income.
Third, mechanical stimulation of certain crops (such as vegetables, potatoes, and millet, etc.) topping, topping, or smearing, etc., can achieve the “top advantage†of suppressing crop reproductive centers and promote the growth of branches. Increase the proportion of female flowers, etc. to increase production. Others, such as timely emasculation of corn, can reduce nutrient consumption and increase grain filling degree; sweet potato “tangle†(not tumbling) can inhibit the growth of adventitious roots and concentrate the supply of nutrients to the tuber; The Division promotes the growth of its adventitious roots, allowing it to expand the area of ​​nutrient absorption to enlarge the fruits and berries. Experienced old farmers use bamboo sticks to puncture the base of the stalks of pumpkins, which can stimulate them to open more female flowers and produce more melons.
Fourth, the scientific interplanting of intercropping crops between sciences is an effective measure to make full use of land and increase production and income. However, in order to ensure the balanced growth of primary and secondary crops and achieve stable yields and high yields, it is necessary to determine the length of growth of different crops, the depth of root distribution, the height of plants, the distribution of plant types, the width and width of the leaves, and the differences in adaptability. Such as, to achieve a reasonable and orderly arrangement, and the mutual rotation between different crops, it is an important farming system, must be established on the basis of a relatively long-term basis. It is generally applied to production, mainly for crop rotation (such as rice and peanut rotation), rotation between different crops under the same soil conditions (such as dryland corn and vegetable crop rotation, etc.), and the rotation of different crops of the same crop (such as vegetables Rotation of fruit vegetables and leafy vegetables in crops, etc.). Although the forms of rotation vary, they all need to be scientifically arranged according to the demand of different crops (or varieties) on soil nutrients, the impact on soil fertility, the depth of root distribution, and the difference in pest resistance. To complement each other, coordinate births, increase land resources, reduce pests and diseases, increase production and increase revenue for the purpose of rotation.
