Pear planting density
The planting density of pear trees can be determined according to variety type, tree size, tree planting technology, climatic environment, soil environment and root living environment. In general, for varieties with large crown, many branches and vigorous growth, the planting density can be 4-5m per plant row spacing.

High-yield cultivation techniques of uniform planting of soybean
The main results are as follows: 1. the planting density, row spacing and plant spacing are determined according to the plant type and branching characteristics of the variety. The main stem type varieties of ① with dwarf, precocious and anti-nephew branching: row spacing 30-40 cm, plant spacing 8-10 cm, seedling density 1.8-25000 plants. 2. the planting density is determined by the level of soil fertility and management level. After the planting row spacing is determined according to the variety, the density should be adjusted according to the soil fertility and the level of water and fertilizer management. 3. Sow as early as you can. Early sowing can significantly increase yield and fat content.

High density cultivation Model of Cotton with one Film and five elements
Cotton boll opening period management to grasp the "four skillful" (skillfully grasping fertilizer and water, skillfully pruning, skillfully picking rotten bolls, skillfully ripening). 1. Skillfully grasp fertilizer and water to promote the movement of nutrients. One is extra-root topdressing. For cotton fields with premature loss of green leaves and early senescence, foliar spraying with 50-60 kg urea solution of 1%-2% per mu is used to prolong the leaves.

Reasonable planting density of the latest Maize
The planting density of maize is one of the factors that directly affect the yield of maize. Practice has proved that in a certain range, the yield of corn increases with the increase of density, and when the density reaches a certain value, the increase of density decreases the yield. So the appropriate density is

Study on the efficiency of Cotton Light Table in different planting patterns
In order to further increase the cotton yield, it is difficult to increase the number of plants per unit area. In production, it is necessary to increase the density, improve the poor ventilation and light transmittance in the middle and lower part of the cotton population, and improve the light transmittance and photosynthetic efficiency in the middle and lower part of the cotton population. In this paper, through the study of cotton population photosynthetic efficiency and light transmittance of different planting patterns, in order to determine the reasonable cotton population structure in specific areas, and to provide a basis for high-yield and high-quality cotton cultivation. Materials and methods 1. The general situation of the test was conducted in 2002-2003.
