Four measures to promote crop production and increase income
I. Pay attention to the close contrast tests conducted by the crop plantation line to foreign countries who had 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 dry soils or seasons with scarce rain, it is recommended to plant against the wind (that is, in the direction perpendicular to the wind direction). 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 better to select the wind direction, that is, parallel to the direction and direction of wind, which is conducive to the adjustment of temperature and humidity of the soil 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 improve the filling degree of pods; sweet potato “ritch vines†(not vines) can inhibit the growth of adventitious roots, so that nutrients can be concentrated to supply yam; the “pressure vines†of watermelons are 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 to 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 based on a relatively long-term basis of stability. 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 maize and vegetable crop rotation, etc.), and crop rotation between different crops (such as vegetables). Rotation of fruit vegetables and leafy vegetables in crops, etc.). Although the forms of rotation vary, they must 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.
