Analysis of Key Technologies and Economic Benefits of Deep-Buried Drip Irrigation for Cotton
Cotton "deep-buried" drip irrigation technology is another new high-efficiency water-use technology that has emerged following cotton subsurface hose micro-porous irrigation technology. This technology can utilize fertilizer and water with high efficiency, and its yield-increasing effect is obvious. I. Key Technologies 1. Irrigation The start of irrigation is at the cotton squaring stage. In the cotton region of northern Xinjiang, this is generally June 7-10, with irrigation carried out on a 3-day rotation cycle. If autumn is rainy, irrigation can be carried out on a 5-day cycle. Irrigation amount: at the squaring stage, each irrigation is 8 cubic meters per 667 sq m; at full flowering, 10 cubic

Key Technical Points for Cultivation and Management of Cotton under Hose Drip Irrigation
As the crop area in Jimsar County has increased year by year, water resources have become scarce, and the cost of cotton has risen, the comparative benefit of cotton has declined year by year. For this reason, we introduced and promoted the technique of cotton drip irrigation under film at normal pressure (hose). I. Main indicators 1. Yield: 100-130 kg of lint cotton per 667 sq m. Yield composition: 13,000-15,000 harvested plants per 667 sq m, 5-6 bolls per plant, 5 g per boll, lint percentage 33%-35%. 2. Fertilizer and water

Detailed Explanation of Key Technical Points for Drip Irrigation and Fertigation under Cotton Mulch
Drip irrigation under cotton mulch is a new water-saving technology that allows artificial control of irrigation volume and field microclimate, greatly alleviating the **tension of water use for the first irrigation, and can control the reproductive growth and vegetative growth of cotton, helping to shape an ideal plant architecture and reduce ineffective nutrient consumption. Although some problems still exist in practical application, cotton under drip irrigation generally opens bolls earlier, has better quality and higher yield. At the same time, under special climatic conditions, drip irrigation has demonstrated unique cold resistance. When encountering special low-temperature conditions in spring and autumn, growth and development remain normal, with strong high and stable yield, and a relatively concentrated maturity period.

Detailed Explanation of Key Points of Cotton Cultivation Technology with Drip Irrigation under Plastic Film
I. Pre-sowing Preparation 1. Variety Selection: According to climate and soil conditions, select varieties with a growth period of about 130 days, resistance to Fusarium and Verticillium wilt; compact plant type, short fruiting branches type I~II, small insertion angle; moderate to small leaves, short petioles, not prone to vegetative branches; strong boll setting, and good fiber quality. Such as 9665, JD~3, Fengmian No. 8, Jiumian No. 2, etc. 2. Deep Application of Base Fertilizer: The amount of chemical fertilizer is 8~12 kg of pure nitrogen, 7~10 kg of phosphorus pentoxide, and 3.5 kg of potassium oxide. When deep plowing to kill stubble, apply farmyard manure

Detailed Explanation of Agronomic Supporting Techniques for Drip Irrigation Under Plastic Mulch in Cotton
Drip irrigation under plastic mulch is a technique that combines drip irrigation technology with plastic film mulching cultivation technology. Water is supplied through a controllable pipeline system; after water and fertilizer are mixed, they are delivered drop by drop evenly, at set times and in set amounts, moistening the crop root development zone and always keeping the root-zone soil loose and at optimal moisture. It reduces evaporation between crops and improves water use efficiency. 1. Irrigation regime. For subsurface drip irrigation, total water use was 175.48 million cubic meters. Dripping was done 9 times. For precision drip irrigation, total water use was 177.84 million cubic meters. Dripping

What to do about premature senescence in high-density drip-irrigated cotton? Main causes and preventive measures
I. Main causes of premature senescence in high-density cotton planting 1. Variety factors Varieties are not resistant to premature senescence. In recent years there have been many cotton varieties; some have aged and degenerated, and some are inherently poor in disease resistance and premature senescence resistance, or are unsuitable for high-density planting, leading to premature senescence in cotton. 2. Environmental factors ① Temperature For mid-early maturing cotton, the suitable sowing period is when the 5 cm soil temperature stably passes 12°C. If sowing is too early or the seedling stage encounters low-temperature chilling injury, because the air temperature is relatively low, root growth is slow and diseases are severe, which easily damages the cotton root system function, thereby

Analysis of the Causes of Premature Senescence in Drip-Irrigated Cotton and Control Measures
Since 2002, Regiment 141 has widely promoted drip irrigation technology for cotton cultivation, with yields increasing year by year and remarkable economic benefits. However, in recent years, premature senescence has occurred to varying degrees in cotton fields, causing poor boll opening, shell clamping, and an increase in hardened and stiff boll segments and tips, reducing quality. I. Causes of Premature Senescence 1. Long continuous cropping years Newly reclaimed cotton fields and those with a short history of cotton planting mostly show green branches and leaves; old cotton fields with 10 or more years of continuous cropping grow well in the early stage, but once they encounter low temperatures and continuous rain in the middle and late stages, red leaf symptoms occur on a large scale.

Cotton drip irrigation automation project boosts yields
The Shihezi "Cotton Drip Irrigation Automatic Control Science and Technology Demonstration Project", which has been included in the national plan, will add another 15,000 mu to its experimental demonstration area this year on top of last year's. In recent years, after the Shihezi reclamation area vigorously promoted and applied cotton under-mulch drip irrigation technology, total cotton output and per-unit yield have increased substantially. **Tianye Group Corporation, as the largest domestic producer of agricultural water-saving drip irrigation equipment, has promoted water-saving drip irrigation over more than ten million mu. In order to seize the scientific and technological high ground, the company independently innovated and developed the "Cotton Drip Irrigation Automation

The 10th Regiment of the First Agricultural Division pioneers a new water-saving technique for dryland rice cultivation with drip irrigation under plastic film
In 2010, the 10th Regiment of the First Agricultural Division of the **Production and Construction Corps used new science and new technology to transform traditional agriculture. Faced with a severe shortage of water resources and its disadvantaged position as a unit downstream of the First Division's water supply, it independently developed new machinery for sowing rice on dryland with drip irrigation under plastic film, which was put into rice production and vigorously promoted by Aral City of the First Division. According to Kong Jun, the First Division's deputy division commander in charge of agriculture, this cultivation model not only saves labor in rice planting but also conserves water resources and farmland costs, helping to increase rice yields and efficiency, and it has opened a new chapter for the Corps' agriculture and livestock farms.

What to Do When Alocasia (Dripping Guanyin) Roots Rot? Cause Analysis and Treatment Methods
What to do when Alocasia (Dripping Guanyin) roots rot: causes of root rot in Alocasia. Alocasia can be grown in soil or in water. Root rot in soil-grown Alocasia is mainly caused by the potting soil being too wet. When the potting soil is too wet, rot of the rhizome is very likely to occur. The cause of overly wet potting soil may be that you watered too much
