State trial of Handan 284 cotton
Handan 284 cotton was selected and bred by Handan Institute of Agricultural Sciences in Hebei Province. it was approved by the National crop New Variety examination and approval Committee in 2001 and listed as a variety of "National Science and Technology key extension Plan" by the Ministry of Science and Technology in 2002. Xinxiang Xincheng seed industry has the right to develop and manage this variety in China. The variety was not sown on April 15-20 with plastic film mulching, and sown in open field on April 20-30, with 1600 plants per mu and 2000 plants per mu in dry and thin land. 1999 / 2000

About cotton cultivation
(i) Remove leaves. It is commonly known as "hitting the public branch." Leaves grow fast, consume more nutrients, inhibit the growth of fruit branches and affect the development of buds and bolls, at the same time cause poor ventilation in the lower part of cotton plants, easy to produce diseases and insect pests, so that buds and bolls fall off, so it should be removed in time. If the cotton plant grows too vigorously, it can also knock off the leaves and leaves under the fruit branches together, which is called "taking off the trouser legs" by the masses. When taking off the trouser legs, if the buds have appeared on the leaves, the top center of the leaves can be knocked off and reformed. (b) Scrubs. Commonly known as "wipe ears." Vegetation growing at the junction of fruit branch and main stem, wasting nutrients

It is cost-effective to apply peach fertilizer to cotton
This year, due to the influence of drought and waterlogging and the recent hot and high temperature, the progress of cotton development is very uneven, especially the number of peaches in cotton is very different. in cotton fields with earlier planting and better management, there are an average of 810 early-season peaches per plant in cotton fields. High-yield farmers have more than 20 cotton early-season peaches, while in general, there are only 4-6 cotton early-season peaches in the field. In terms of cotton growth process, field cotton has now generally entered the boll setting period. The period when cotton is concentrated on peach is the period when the largest amount of fertilizer is needed. Judging from the period of cotton and peach bearing

Effect of dry sowing Wet Water output on Cotton
In recent years, with the large-scale popularization of conventional drip irrigation, drip emergence of cotton after sowing has become a conventional technique, which has been adopted by most cotton planting areas. Dripping water at an appropriate time can not only avoid the final frost in April, but also the emergence of cotton seedlings is neat and consistent, the growth potential is better, and it is convenient for field management. However, the amount of water dripping out of seedling water varies from place to place. Our region is a sub-suitable cotton area, there are more cold weather in spring every year, the final frost is mostly around April 20, and the temperature of cotton seedling stage is lower. Cotton root rot is coming back.

Textile knowledge: analysis of similarities and differences between Chinese and American Cotton grading Standards
The United States is a big country in cotton production and consumption in the world. Half of the cotton produced each year is used for domestic consumption and half for export. Therefore, the cotton standard of the United States has an important influence in the world and is used by 24 countries and regions, which is also known as the universal cotton standard. The following is a brief introduction to the similarities and differences between Chinese and American cotton grading standards: cotton grade is the reflection of cotton quality and comprehensive performance, and there is a cotton grade test in the cotton standards of most cotton-producing countries in the world. In the American cotton standard

It is the right time to control cotton aphid
Aphids can be divided into seedling aphids and summer aphids, which are two ecotypes of cotton aphids that differentiate and adapt to different environmental conditions. It is mainly concentrated in the back of cotton leaves or tender head to absorb juice. The summer aphid in the cotton area of the Yellow River basin mainly occurs from the middle of July to the middle of August, which can cause the upper tender leaves of cotton to curl, the middle leaves to appear oil leaves, and seriously lead to the shedding of buds and bolls. Because most of the cotton was ridged and the leaves were dense when the aphids occurred, many farmers reported that the aphids were more difficult to control than seedling aphids. I. the occurrence of cotton aphids is common in Hengshui City at present.

Prevention of "five pests" and "three seedlings" in cotton seedbed
The common problems in cotton nutrition bowl seedling bed are drought, stain, disease, fertilizer, medicine and frozen seedling, burning seedling and line seedling. First, to prevent the "five evils" 1. The water content on the bowl should be moderate. The nutrition bowl seedling bed should be selected in the place of drainage and irrigation, and the water content on the bowl should be dispersed when it falls to the ground by hand. 2. After cotton is sown and covered with soil. It is necessary to pour enough water at one time, and the water should be poured until it permeates slowly; 3, after covering the film, make sure that the moisture is sufficient, do not uncover the film at will, and make sure that the film is not removed until the seedling comes out; 4. Clear water and filtered water should be discharged around the seedling bed.

Techniques of rebuilding Pinus sylvestris var.mongolica young forest into Korean pine nut forest
In recent years, the construction of Korean pine fruit forest and Korean pine nut forest in Heilongjiang and Jilin provinces has developed rapidly. Some places regard the development of Korean pine fruit forest as the way to get rich, and large-scale Korean pine fruit forest has been established. However, due to the deviation in people's understanding, they ignore the selection of fine seed spike grafting to build forest, and the selected seed spike is rarely identified. The establishment of Korean pine nut forest like this without selection can not guarantee the yield and quality of seeds. What's more, it can not guarantee prematurity, high yield and stable yield. It has been proved by practice that the juvenile of Pinus sylvestris var. mongolica
