Water-saving cultivation of cotton in semi-arid saline-alkali soil
Cotton has always been an important economic crop, and the continuous improvement of cotton yield and quality is of great significance to increase agricultural efficiency and increase farmers' income. Over the years, through gradual exploration, a set of relatively complete cotton cultivation techniques in semi-arid saline-alkali land have been formed, and drought-resistant cotton planting has achieved the goal of early maturity, high yield and high quality. The problems of cotton seedling emergence, seedling protection, slow growth and late ripening in saline-alkali soil were solved due to the lack of water resources. The yield-increasing technology of cotton in semi-arid saline-alkali land mainly includes seed preparation, fertilization, chemical control, pruning and so on.

Leguminosae forage grass-- big wing bean
Big wing bean, native to Central and South America, was introduced from Mexico in Australia, and was introduced by Australia in 1974. Now it is planted in Guangxi, Guangdong, Fujian, Jiangxi and other provinces with good performance. The leaves of large-winged beans are green and sparsely hairy, with silver-gray fine hairy hairs on the back, and dark purple racemes. Is an excellent legume forage, green feeding or preparation of hay can be, cattle, sheep like to eat, especially deer like to eat, seeds for quail, pigeon, turkey and other birds like to eat. Strong regeneration, can be cut 2 to 3 times a year, fresh per hectare

Growth characteristics and Fertilizer and Water Management of Cotton at Bud stage
The growth characteristics of cotton at bud stage cotton entered a period of both vegetative growth and reproductive growth from the beginning of budding, but it was still dominated by vegetative growth. The photosynthates in the bud stage are mainly transported to the vigorous growth parts of the main stem and fruit branches, and few are supplied to the buds. With the rising temperature, the growth of roots, stems, leaves, fruit branches and flower buds of cotton is obviously accelerated, plant metabolism is more and more exuberant, physiological activities are enhanced, photosynthetic productivity is high, and root growth reaches a vigorous period. The main purpose of this period of management is to grow stably and build a high yield shelf. The growth of normal cotton at bud stage.

Strengthening Fertilizer and Water Management to prevent premature senescence of Cotton
Recently, there is a trend of premature senescence in some cotton fields, so measures must be taken as soon as possible to ensure high cotton yield. It mainly shows that the red stem to the top of the cotton plant, the stem is hard and inelastic, the growth point of the main stem is prominent, it is difficult to extend the new fruit branches and nodes, the leaves fade, the new leaves are small, the leaves of the middle and lower parts of the cotton plant appear reddish brown spots, and the basal leaves wither; the leaf margin scorched and fell off prematurely. The cause of premature senility (1) the weather is unfavorable. This year, cotton suffered a severe drought in the early stage of growth and waterlogging in the middle stage, resulting in poor root growth and fertilizer absorption.

Remedial measures for Frost injury of Tea trees
From February 15 to 18, we investigated the freezing injury of tea trees in Zixingtang City, Pengshi City, Guocha Institute and Chenzhou Huatang Tea Farm. The investigation found that in the well-cultivated tea garden, the green leaves of the tea trees are thick, the trees are strong, and the degree of disaster is mild, and vice versa. The disaster degree of different varieties was also different, among which the early varieties Fuyun 6 and Fuding Dahao and Bai Maozao were seriously affected, while the middle and late varieties Bixiangzao, Qianye Qi, hairy crab and population varieties were less affected. On the whole, all the tea trees in the survey sites suffered frost injury, among which the disaster was more serious.

Key points of production recovery Technology of Tea trees after Snow disaster and Frost injury
This year, some tea areas across the country experienced severe weather such as heavy snow and low temperature freezing, which caused different degrees of snow disaster and freezing damage, such as broken branches, discolored leaves, withered branches and so on. In order to resume tea production and reduce the economic loss of tea farmers as soon as possible, in view of the occurrence of disasters, the following technical points are put forward. 1. Pruning 1. Mild frost injury (only leaves are damaged): no pruning or light pruning as appropriate. 2. Moderate freezing injury (damage to production branches) and severe freezing injury (damage to backbone branches): pruning when the boundary between the frozen dead part and the healthy part is clear.

Seven measures for Prevention and Control of Frost injury of Young Tea trees
1. Apply wax fertilizer. The cold resistance of young tea trees is relatively weak, so it is necessary to re-apply wax fertilizer before overwintering. Fertilizers are mainly soil manure, barnyard manure and biogas residue with certain heat preservation effect, while a certain amount of cake fertilizer, calcium superphosphate and potassium sulfate fertilizer are applied at the same time. Wax fertilizer can not only play the role of heat preservation and anti-freezing, enhance the frost resistance of tea trees, but also lay a good foundation for the growth of tea trees in the coming year. two。 Cultivate the earth and choke it. To prevent the root neck from freezing is the key measure to prevent the freezing of young tea trees. Therefore, before the young tea trees overwintered, they should

Take active measures to prevent and control the freezing injury of tea trees
Freezing injury is the main weather disaster suffered by tea trees. After the tea tree suffered from frost injury, it would affect the yield and quality of tea, and seriously cause serious defoliation and even death of the whole plant. According to the growing season, tea freezing injury can be divided into overwintering freezing injury and budding freezing injury, and the latter has the greatest influence on the yield and quality of spring tea in that year. During the overwintering period, the prevention of freezing injury in the growing season should strengthen the management of fertilizer cultivation, pay attention to the prevention of diseases and insect pests, and implement the combination of collection and cultivation to promote the healthy growth of tea trees, so as to accumulate more organic matter and improve their resistance to low temperature.

Cultivation techniques of Film mulching between large ridges and upward ridges of Soybean
Heilongjiang Province is the main soybean producing area in China, its planting area accounts for 7% of the country's total output, accounting for 11% of the country's total output. In the process of soybean production and development, Heilongjiang reclamation area has vigorously promoted scientific and technological innovation, which has greatly improved the per unit area yield and total yield of soybean. From 2001 to 2005, the average yield per hectare reached 2531.7kg, and in 2005, the average yield per mu of soybean reached 178kg, which reached or close to that of advanced countries in the world. Cultivation techniques of Film mulching between large ridges and upward ridges of Soybean

Cultivation Technique of Soybean-Soybean "Ridge Three"
In the early 1980s, Heilongjiang Bayi Agricultural Reclamation University adopted the combination of agricultural machinery and agronomy, and gradually formed a complete set of effective mechanized high-yield comprehensive cultivation technology system of soybean, called "ridge three"(or "ridge three") cultivation technology. The so-called "ridge three" refers to the adoption of three mechanized operation techniques on the basis of ridge cultivation: one is deep loosening at intervals between ridges and furrows, the other is deep application of base fertilizer in layers, and the third is double strip precision sowing on ridges. The above three operations are completed by machinery at one time. After this technology is popularized, according to
