引言:

新疆是(shì)我國(guó)重要(yào)的(de)棉花(huā)産區(qū),棉花(huā)種植對(duì)于當地(dì)經濟發展和(hé)農(nóng)民(mín)收入具有(×yǒu)重要(yào)意義。7 月(yuè)是(shì)棉花(huā)生(shēng)長(cháng)的(de)關鍵時(shí)期,此時(shí)的(de)管理(lǐ)措施直接影(yǐng)響著(zhe)棉花(huā)的(d"e)産量和(hé)品質。


新疆7月(yuè)氣候特點


7 月(yuè)新疆氣溫較高(gāo),平均氣溫在 25℃以上(shàng),有(yǒu)利于棉花(huā)的(de)生(shēng)長(cβháng)和(hé)發育,但(dàn)高(gāo)溫也(yě)可(kě)能(néng)導緻棉花(huā)蕾鈴脫落 。

7 月(yuè)降水(shuǐ)相(xiàng)對(duì)較少(shǎo),部分(fēn)地(dì)區(qū)可(kě)能(néng)出現(xiàn)幹旱,需要(yào)合理(lǐ)灌溉以滿足棉花(huā)生(shēng)長(cháng₩)的(de)水(shuǐ)分(fēn)需求。

充足的(de)光(guāng)照(zhào)條件(jiàn)為(wèi)棉花(huā)光(guāng)合作(zuò)用(yòng)提供了(le)良好(hǎo)的(de)環境,但(dàn)強光(guāng₩)照(zhào)也(yě)可(kě)能(néng)對(duì)棉花(huā)造成一(yī)定的(de)脅迫。


棉花(huā)7月(yuè)生(shēng)長(cháng)特點


7 月(yuè)棉花(huā)植株營養生(shēng)長(cháng)與生(shēng)殖生(shēng)長(cháng)齊頭并進,需要(yào)合理(lǐ)調配養分(fēn)供應。

此時(shí)是(shì)棉花(huā)蕾鈴形成的(de)高(gāo)峰期,對(duì)養分(fēn)和(hé★)水(shuǐ)分(fēn)的(de)需求急劇(jù)增加。


7月(yuè)棉花(huā)管理(lǐ)的(de)主要(yào)措施



一(yī)、病蟲害防治



棉蚜

發生(shēng)特點:土(tǔ)傳病害,在高(gāo)溫高(gāo)濕條件(jiàn)下(xià)易發病。

防治方法:選用(yòng)抗病品種,合理(lǐ)輪作(zuò),發病初期可(kě)用(yòng)多(duō)菌靈、甲基硫菌靈等藥劑灌根。例如(rú),用(yòng) 50%多(duō)菌靈可(kě)濕性粉劑 500 倍液灌根,每株灌藥液 250 - 500 毫升。₽


二、水(shuǐ)肥管理(lǐ)


 施肥

重施花(huā)鈴肥:根據棉花(huā)長(cháng)勢,每畝可(kě)選擇施用(yòng)赫蔓系列、施芬滿意系列、或愛(ài)萊沃系列大(dà)量元素水(shuǐ)溶肥料1-2kg,可(kě)根據長(cháng)勢情況增施司普沃其他(tā)功效肥料,可(kě)有(yǒu)效促進棉花(huā)花(huā)®鈴多(duō),雙蕾多(duō)。

另外(wài),可(kě)以補施葉面肥:噴施磷酸二氫鉀、硼肥等,提高(gāo)棉花(huā)的(de)結鈴率。

司普沃産品多(duō)樣,不(bù)同土(tǔ)壤問(wèn)題、作(zuò)物(wù)生(shēng)長(cháng)問(wèn)題都(dōu)有(yǒu)針對(duì)性解決←方案,專肥專用(yòng)更具針對(duì)性,使用(yòng)效果更突出!


澆水(shuǐ)

灌溉頻(pín)率:根據土(tǔ)壤墒情,每隔 7 - 10 天澆水(shuǐ)一(yī)次,保持田間(j&iān)持水(shuǐ)量在 60% - 70%。

灌溉方式:采用(yòng)滴灌或溝灌,避免大(dà)水(shuǐ)漫灌。



三、整枝打頂


打頂時(shí)間(jiān):一(yī)般在 7 月(yuè)中旬進行(xíng),當棉花(huā)主莖有(yǒu) 7 - 8 ÷個(gè)果枝時(shí)及時(shí)打頂。


操作(zuò)方法:去(qù)除主莖頂端生(shēng)長(cháng)點,控制(zhì)棉花(huā)株高(gāo),促進養分(fēn)向蕾鈴輸送。


四、化(huà)學調控


在棉花(huā)種植中,化(huà)控通(tōng)常指的(de)是(shì)通(tōng)過化(huà)學手段調節棉花(huā)的(de)生(shēng)長(ch↑áng),以控制(zhì)其高(gāo)度、株型、開(kāi)花(huā)和(hé)結果等。這(zhè)種調節是(shì)基于棉花(huā)生(shēng)長(cháng)的$(de)特點和(hé)需要(yào),以及種植者的(de)目标來(lái)确定的(de)。


然而,一(yī)些(xiē)種植者擔心化(huà)控會(huì)使棉花(huā)生(shēng)長(cháng)受≈限甚至停止,這(zhè)源于對(duì)化(huà)控技(jì)術(shù)的(de)誤解或過度擔憂。


實際上(shàng),合理(lǐ)化(huà)控能(néng)優化(huà)棉花(huā)生(shēng)長(cháng)結構,提高(gāo)光(guāng)≈能(néng)利用(yòng)率,增強抗性,實現(xiàn)穩産增産。為(wèi)确保棉花(huā)穩健生(shēng)長(cháng),應采取“少(shǎo)量多(duō)次勤控”的(de)策略,即根據生(shēng)長(cháng)情況和(hé)需要(yào)适↔時(shí)适量化(huà)控,多(duō)次輕度調節,避免一(yī)次性過度調節的(de)不(bù)良≥影(yǐng)響。


調控藥劑:

使用(yòng)縮節胺等植物(wù)生(shēng)長(cháng)調節劑,根據棉花(huā)長(cháng)勢和(hé)天氣情況,合理(lǐ)調整用(yòn¥g)藥劑量。


注意!田間(jiān)管理(lǐ)小(xiǎo)技(jì)巧


1、及時(shí)中耕除草(cǎo)
疏松土(tǔ)壤,提高(gāo)土(tǔ)壤透氣性,減少(shǎo)雜(zá)草(cǎo)與棉花(huā)争肥争水(shuǐ)。


2、加強田間(jiān)監測
定期觀察棉花(huā)生(shēng)長(cháng)情況,及時(shí)發現(xiàn)問(wèn)題并采取相(x¶iàng)應措施。


3、注意農(nóng)藥安全使用(yòng)
嚴格按照(zhào)農(nóng)藥說(shuō)明(míng)書(shū)使用(yòng),遵守安全間(jiān)隔期,防止農("nóng)藥殘留超标。


7 月(yuè)是(shì)新疆棉花(huā)生(shēng)長(cháng)的(de)關鍵時(shí)期,科(kē)學合←理(lǐ)的(de)管理(lǐ)措施對(duì)于提高(gāo)棉花(huā)産量和(hé)品質至關重要(yào)。種植者應根據當地(dì)的(de)氣候條件§(jiàn)和(hé)棉花(huā)生(shēng)長(cháng)狀況,做(zuò)好(hǎo)病蟲害防治、水(shuǐ)肥管理(lǐ)、整枝打頂和(hé)化(huà)¥學調控等工(gōng)作(zuò),為(wèi)棉花(huā)的(de)豐收奠定堅實基礎。

Focus on July: Secrets of Xinjiang Cotton Management


Introduction:
Xinjiang is an important cotton-producing area in China. Cotton planting is∑ of great significance to the local economic development and♥ farmers' income. July is a critical period for cotton growth, and the management measures duri₽ng this time directly affect the yield and quality of cotton.


Climate Characteristics of Xinjiang in July


The temperature in Xinjiang is relatively high in July, with an average temperature above 25°C, whπich is conducive to the growth and development of cotton. However, high temperatur♥es may also lead to the shedding of cotton buds and bolls.
Precipitation is relatively low in July, and drought may occur in some areas. Reasonable irrigation™ is needed to meet the water requirements of cotton growth.
Sufficient light conditions provide a good environment fo₽r cotton photosynthesis, but strong light may also cause certain stress to cotton.


Growth Characteristics of Cotton in July
In July, the vegetative growth and reproductive growth of cott≤on plants proceed simultaneously, and a reasonable allocation of nutrient∏ supply is required.
This is the peak period for the formation of cotton bu★ds and bolls, and the demand for nutrients and water increases sharply.


Main Management Measures for Cotton in July


(I) Pest and Disease Control

Cotton aphids
Occurrence characteristics: They reproduce rapidly and are prone to outbreaks under ←high-temperature and drought conditions.
Control methods: Agents such as acetamiprid and imidaclo♠prid can be used for spray control. For example, in the early stage of cotton aphid occurren ce, use a 2000-fold solution of 10% imidacloprid wettable p✔owder for spraying, once every 7 - 10 days, for 2 - 3 consecutive times.

Cotton bollworm
Occurrence characteristics: The larvae bore into cotto n bolls, causing a large number of bolls to fall.
Control methods: Use sex pheromone traps to catch adults, or use agents such as £emamectin benzoate and chlorantraniliprole for spray cont∏rol during the peak hatching period of larvae. For example, use a 3000-fold solutαion of 5% emamectin benzoate water-dispersible granules for πspraying.

Fusarium wilt and Verticillium wilt
Occurrence characteristics: Soil-borne diseases th©at are prone to occur under high-temperature and high-humidity conditions.
Control methods: Select disease-resistant varieties, conduct reasonable crop ro✘tation, and use agents such as carbendazim and thiophanate-methyl for root iλrrigation at the early stage of disease occurrence. For€ example, use a 500-fold solution of 50% carbendazim wettable powder for root irrigation, wit♣h 250 - 500 milliliters of liquid per plant.




(II) Water and Fertilizer Management


Fertilization


Emphasis on flowering and boll-forming fertilizer: Dependin✔g on the growth status of cotton, 1-2 kg of high-analysis water-soluble fertilizers from the seri es of Hermang, Shifenyimanyi, or Ailaiwo can be selected for application per acre. Other functiona♦l fertilizers from Sipuwo can be applied in addition based on the ₽growth conditions, which can effectively promote the production♦ of more flowers and bolls with more double buds.


Additionally, foliar fertilizers can be supplemented: Spraying potassium dihydrogen phγosphate, boron fertilizer, etc., can improve the boll-setting ↑rate of cotton.


Sipuwo offers a wide range of products, and each soil problem or crop growth issue has✘ a targeted solution. Using specialized fertilizers with a higher degree™ of targeting leads to more outstanding results!



Watering
Irrigation frequency: Water once every 7 - 10 days based on ←soil moisture conditions to maintain the field water holding cap¥acity at 60% - 70%.
Irrigation method: Adopt drip irrigation or furrow irrigation to avoid flood irrigation.


(III) Pruning and Topping


Topping time
It is generally carried out in mid-July. Topping should be done in time when ther e are 7 - 8 fruit branches on the main stem of cot‌ton.
Operation method
Remove the growth point at the top of the main stem to control the height of the cotton♥ plant and promote the transportation of nutrients to the buds and bolls.


(IV) Chemical Regulation


In cotton planting, chemical control usually refers to regulating the gr∏owth of cotton through chemical means to control its height, plant type, flowering, and fr→uiting. This regulation is determined based on the characteristics and needs of cotton grow•th, as well as the goals of growers.


However, some growers are worried that chemical control will limit or even st≠op the growth of cotton, which stems from misunderstandings or excess™ive concerns about chemical control technology.


In fact, reasonable chemical control can optimize the growth structure of cotton, improve light  energy utilization rate, enhance resistance, and achieve stable and increased yields. ¥To ensure the steady growth of cotton, the strategy of "small amounts, multip¥le times, and frequent control" should be adopted, that is, timely and appropriately control↑ according to the growth situation and needs, and make multiple mild adjustments to avoid th≤e adverse effects of one-time excessive adjustment.


Regulation agents:
Use plant growth regulators such as mepiquat chloride, and adjust th≤e dosage of the drug reasonably according to the growth of cotton and weather conditi×ons.


Attention! Field Management Tips


Timely intertillage and weeding
Loosen the soil, improve soil permeability, and reduce competition for fertilizer and w'ater between weeds and cotton.

Strengthen field monitoring
Regularly observe the growth of cotton, discover problems in time, and take c<orresponding measures.

Pay attention to the safe use of pesticides
Use strictly in accordance with the pesticide manual, o∑bserve the safety interval, and prevent excessive pesticide residues.


July is a critical period for the growth of cotton in Xinjiang. Sc£ientific and reasonable management measures are crucial for ∑improving the yield and quality of cotton. Growers should do a goλod job in pest and disease control, water and fertilizer management, pruning a>nd topping, and chemical regulation based on local clim₽ate conditions and the growth status of cotton, lay ing a solid foundation for a bumper cotton harvest.
