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

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.

The cultivation density of peach trees varies according to the density of the tree shape.
The cultivation density of peach trees should be adjusted according to the tree shape of peach trees, if the three main happy crown seedlings are cultivated, the row spacing should be controlled at about 3-5 meters, the planting density should be controlled at about 45 trees per mu, and if Y-shaped seedlings are cultivated, the row spacing should be controlled at

Suitable density for feeding pigs
The feeding density of pigs refers to the pigsty area occupied by each pig, usually expressed as "┫ / head". The breeding density indicates the density of pigs in the house. The feeding density has a great influence on the air environment in the house. A large number of raising in the house will give off more heat, which is beneficial to the heat preservation of the pig house in winter, but not conducive to the heat prevention and cooling in summer, and increases the contents of harmful gases, water vapor, dust and microorganisms in the house. at the same time, it also makes the struggle between pigs frequent, affecting feeding and rest. If the number of animals raised in the house is small,

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.

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.

Effect of different density on yield of Potato cultivated in Open Field
Potato is mainly cultivated as early-maturing vegetables in Tongren City. In order to explore the best density of virus-free potato cultivated in open field, the density experiment of virus-free potato was carried out in Tongren Agricultural Technology Station from 2006 to 2007. 1 Materials and methods 1.1 the general situation of the experimental site was selected in the responsible field of Yang Xiudong family of Hongdong Group, Mulong Village, Bazhuang Town, Tongren City, with an altitude of 260m. The texture of the experimental field was sandy soil with medium fertility and was used as the root of Houttuynia cordata. 1.2 the tested varieties are the first-class production species of "virus-free Mila", which are produced by
