Embodiment 1
[0044] A cultivation method for a new cotton variety is specially formulated for the Xinluzao No. 74 cotton variety, comprising the following steps:
[0045] 1. Sowing:
[0046] 1.1 Timely soil preparation: choose the appropriate time to cultivate the land, the plowing depth should reach 25-30cm, the plowing should be even, the surface should be flat, the soil should be prepared with good moisture content, the soil should be finely divided, and the upper part should be empty and the lower part should be solid.
[0047] 1.2 Timely sowing: When the ground temperature 5cm under the mulch is stable and passes 12°C, and the relative soil humidity is 65%-80%, it is suitable for sowing. In normal years, trial sowing is carried out in early April, and mass sowing is carried out on April 15. The sowing ends before April 25.
[0048] 1.3 Sowing amount and sowing depth: adopt precision (1 hole, 1 grain) sowing technology. The sowing depth is 1.5cm, and the covering soil thickness is 1-1...

Abstract
The invention discloses a cultivation method of a new cotton variety. The cultivation method comprises the following steps that firstly, sowing is conducted , wherein the sowing step comprises the sub-steps of land preparation, sowing in good time and control over the sowing quantity, the sowing depth and the sowing quality requirements; secondly, field management is conducted, wherein the step offield management comprises the sub-steps of drip irrigation for seedling emergence, hardening breaking, reseeding, timely intertillage, fertilizer conditioning, water and fertilizer management and topping; thirdly, disease and pest control is conducted. The cultivation method has the advantages that the cultivation method of the new cotton variety is high in yield and quality, the early, dense, dwarf, mulching and uniform high-yield cotton cultivation technology is carried out, key technologies, such as film mulching for increasing temperature, reasonable dense planting, drip irrigation for seedling emergence, current fertilizer conditioning, timely defoliation, are applied in the key periods, such as sowing, seedling emergence, topping and defoliation, the four key production links of preparation before sowing, sowing to guarantee full seedlings, field management and harvesting are well managed, the dynamic field indicators that cotton seedlings emerge in April, cotton buds emerge inMay, cotton flowers emerge in June, cotton bolls emerge in July and cotton batting emerges in August are achieved, and the high-yield, high-quality and efficient aims are achieved.
Description
technical field [0001] The invention relates to the technical field of crop planting and cultivation, in particular to a cultivation method of a new cotton variety. Background technique [0002] Cotton production in Xinjiang Corps is a pillar industry in the region, not only of great significance to Xinjiang's economic construction, but also plays a pivotal role in the country's cotton production. Due to the special ecological environment and natural conditions in the early-maturing cotton area of northern Xinjiang, the varieties introduced from the inland generally show late maturity and poor adaptability, and cannot be widely planted in northern Xinjiang. The production of seeds must follow the road of self-fertilization. The Xinjiang Cotton Research Institute has bred the Xinluzao series of new cotton varieties suitable for machine harvesting, and each cotton variety has its own characteristics. The improved varieties are matched with good methods, and field cultivation...
