Cotton Planting Time

Under normal conditions, cotton is suitable for planting around April to May.

Little Cultivation Tips for Cotton

(1) Plot selection: Cotton is a temperature-loving and light-loving crop. Liaoning belongs to the extra-early-maturing cotton region and is the province with the highest latitude among the cotton regions nationwide; the cold and cool areas of the north are not suitable for planting cotton. Cotton has a well-developed root system, with roots reaching more than 2 m deep. Therefore, cotton fields should be chosen on level ground or sunny slopes with deep soil layers and medium or higher fertility. Heavy clay soil, shady sites and waterlogged, cold, sticky land are not suitable for planting cotton. As the farming proverb says: "Cotton seedlings are like fire; sandy loam is best."

(2) Ridging: Cotton seeds have strong soil-penetrating ability and must bring out two leaves as they emerge, so resistance is great. Moreover, increased cotton yields in Liaoning mainly depend on the plant population, and a certain density must be ensured; sowing to secure full stands is the foundation of increased cotton yields. Therefore, cotton field preparation must be meticulous. Cotton seeds absorb water slowly during emergence; the seeds themselves are rich in fat and protein, their material conversion is slow, emergence takes a long time, and water absorption is large (equivalent to the seed weight), so the cotton field must maintain sufficient moisture. Cotton field preparation requires ridging as early as possible; autumn ridging is best, and spring ridging should also be completed before the end of March, no later than April 5 (before Qingming). The soil should be finely prepared with no clods, loose on top and firm below, and soil moisture should be no less than 18%. Fertilization when ridging should be no less than 3000 kg of farmyard manure.

When Is the Best Time to Plant Cotton? Cotton Planting Time and Methods

Cotton is an annual herbaceous plant of the genus Gossypium in the mallow family and is one of the world's most important crops. Cotton has the characteristics of high yield and low production cost. It is both a fiber crop and an important oilseed crop, and can truly be called "treasure from head to toe." So, when is the best time to plant cotton? How should it be planted? The cotton planting time and methods are introduced below.

I. Cotton Planting Time

Because weather and climate differ from region to region, cotton planting time also differs. Generally speaking, cotton planting time is around April each year. In fact, starting in the third month of spring, farmers begin buying cotton seeds to plant cotton, but because cotton is not simply planted directly like beans, at this time they are cultivating cotton seedlings, so the true planting time for cotton should be late March to early April.

II. Cotton Planting Methods

1. Pre-sowing preparation:When buying good cotton seed, it is advocated to change seed every year. Do not be greedy for cheapness and use second- or third-generation cotton seed, because self-saved seed reduces yield by about 10% each year. Use about 1.5 kg of seed per mu. Sun the seed before sowing, with cumulative sunning time of no less than 30 hours, turning it constantly. Note: do not spread it directly on concrete, brick or metal surfaces. Before sowing, soil moisture must be created and preserved in good time, so that sowing is done with sufficient moisture.

2. Fertilization and sowing:Generally, apply 3-4 cubic meters of high-quality farmyard manure per mu, 10 kg of urea, 20 kg of diammonium phosphate, 20 kg of potassium sulfate compound fertilizer, and 2 kg of micronutrient fertilizers such as boron, zinc, manganese and iron. Sowing too early will cause incomplete emergence due to low temperatures, worsen seedling-stage diseases, and lead to premature senescence later. Sowing too late easily causes excessive vegetative growth, bolls set too high, missing the best boll stage, and is unfavorable for high yield. The best sowing period is around April 20, with sowing depth of about 3 cm. According to soil moisture, generally keep it no deeper than one cun and no shallower than exposing the seed; where moisture is good and the soil is rather clayey, sow slightly shallower; where moisture is poor and the soil is sandy, sow slightly deeper.

3. Reasonable close planting:On sandy soil and poor-fertility land, plant appropriately densely; on clay soil and fertile land, plant appropriately sparsely. The recommended practice is wide-narrow row planting, with wide rows about 1 m, narrow rows 55 cm, and plant spacing about 40 cm. Use tractor plastic film mulching for planting. At present, quite a number of cotton farmers leave too many seedlings at the seedling stage, so cotton closes rows early, ventilation and light penetration are poor, photosynthesis decreases, squares and bolls shed severely, cotton pests and diseases worsen, ineffective fruiting branches increase, field operations are unfavorable, and cotton yield and quality decline, affecting income.

4. Topdressing and watering:At the seedling stage, watering is generally not needed. At the flowering and boll stage, topdress 20 kg of urea per mu. In the early flowering stage, if drought generally lasts about 15 days and leaves show slight wilting at noon, water promptly; even if it rains, if the rain does not soak through, watering is still needed. Finally, after cotton bolls open, if drought occurs, water once as well. This can improve root vitality, delay cotton senescence, increase boll weight, and raise yield by about 10%.

5. Chemical regulation and topping:Scientific use of mepiquat chloride and chlormequat is a key measure for building a high-yield framework and obtaining high yield. Chemical regulation begins at the squaring stage: at 6-8 leaves, use 0.5 g of mepiquat chloride per mu; at the early flowering stage, use 1.5 g per mu; after topping, use 3 g per mu. Master the principle of "light first and heavy later, small amounts multiple times." For topping, master "when the time comes, do not wait for branches; when branches come, judge by growth vigor." Generally, cotton fields complete topping on July 15-20.

6. Pest and disease control:At the seedling stage, Tianda 2116 plus hymexazol plus imidacloprid can be used to prevent disease and control insects. Thereafter, add carbendazim solution for sterilization with each spraying. Pesticides such as phoxim, malathion, cypermethrin and abamectin can be used alternately to control cotton bollworm, plant bugs, red spider mites and others. While spraying, alternately add potassium dihydrogen phosphate, urea, micronutrient fertilizers and so on.

[Editor's Conclusion]Cotton is a light-loving crop and is suitable for growing under relatively sufficient light conditions, so special attention is needed during cultivation. The above introduced the cotton planting time and methods for everyone, and we hope it can help you!

Around April on the solar calendar. There is a folk saying that April 11 is the day kapok flowers bloom. The flower language of kapok flower is: cherish the people and happiness around you. So on that day friends send text messages to each other, and couples do too.
The kapok tree is a tropical tree species and likes a climate environment with high temperature and high humidity. Its cold tolerance is relatively low; with long-term low temperatures of 5-8°C, the branches suffer cold injury, and it is averse to frost. In Guangzhou, Nanning and other places in southern South China, it can safely overwinter outdoors in normal years, and in cold years there is freezing injury. In the vast areas from northern South China to North China, it can only be grown in pots, moved into a warm shed or indoors in winter, and room temperature should not be lower than 10°C. It likes sunlight, cannot tolerate shade, and withstands intense sun and high temperatures. It is suitable for planting in sunny places. Its requirements for soil are not very strict; both sandy soil and heavy clay soil are suitable. It likes acidic soil, is relatively tolerant of drought, and also slightly tolerant of waterlogging. Its requirements for fertility are not very high. Generally, in soil with medium fertility and relatively high phosphorus and potassium fertilizer, it blooms profusely and the color is also bright; in soil with sufficient moisture and relatively high nitrogen fertilizer, the branches and leaves are luxuriant and it blooms more, but the color is less bright. When planting, it is suitable to apply decomposed cake fertilizer or garbage as base fertilizer, and before flowering and during peak flowering, topdress with phosphorus and potassium fertilizer. Although the tree shape is not very beautiful, it has sprouting ability, and during management, trunk cutting or pruning and shaping can be used to promote a full crown. It can also be planted 3-5 plants in one place to improve the ornamental effect.
