Abstract

The invention relates to a cotton cultivation method. The cotton cultivation method comprises the following steps of: 1) seeding: seeding in a way of wide-narrow rows, adopting staggered hole seeding in two adjacent rows constituting narrow rows, seeding three nests of seeds in each hole, enabling the three nests to be distributed like a regular triangle, and seeding 3-5 seeds in each nest; and 2) performing field management: timely performing final singling of seeding after cotton seedlings come up out of land, retaining one plant of robust cotton seedling in each nest, and enabling the three plants in each hole to be distributed like the regular triangle. The three plants in each hole are distributed like the regular triangle, thus compared with a planting method of enabling the three plants to crowd together in the prior art, the space is utilized to the greatest extent, land capability and light resources are reasonably utilized, the situation of poor ventilation is improved, and the problems of incapability of reasonably utilizing the land capability and poor ventilation and light transmission of a cultivation mode of planting three plants in one hole in the prior art caused by crowdedness of the plants are solved.

Description

A kind of cotton culture method

Technical field

The present invention relates to a kind of cotton culture method.

Background technology

In order to improve output of cotton, often adopt the cultivation mode of a cave three strains aborning, but existing cultivation mode; Only stress the same cave of three strains, general three strains are squeezed at one, 1 cave because 3 strain plant exist together; Root system is serious to the competition of under ground portion nutrient and moisture, particularly in the competition of low fertility cotton field fierce more, must affect greatly root growth; Simultaneously, the exist together plant stem in 1 cave of acrial part is crowded, is prone to cause ventilation and penetrating light bad; Cause a large amount of bud drops of cotton, the shedding of cotton bolls, nor be beneficial to field management, be difficult to realize the high yield target.

Summary of the invention

The object of the present invention is to provide a kind of cotton culture method, cause rationally to utilize soil fertility, the bad problem of ventilation and penetrating light with plant in the cultivation mode that solves an existing cave three strains.

In order to address the above problem, a kind of cotton culture method of the present invention may further comprise the steps: 1) sowing; Adopt the capable mode of width to sow, adjacent two row that constitute narrow row adopt wrong bunch planting kind, every bunch planting kind three nest seeds; Three nests are equilateral triangle and distribute, and every nest is broadcast 3 ~ 5 seeds; 2) field management, the cotton seedling back final singling in time of being unearthed, every nest keep the healthy and strong cotton seedling of a strain to be made that three strains are equilateral triangle in every cave and distributes.

In said step 2) in, two strains in three strains in each cave of every row are arranged in a straight line and near the clearance space of wide row, remain the clearance space of a strain near narrow row.

In said step 1), the wide 80 ~ 100cm of wide every trade, narrow row line width 40 ~ 60cm.

In said step 2) in every cave spacing in the rows be 10 ~ 15cm.

In said step 1), the cave, adjacent two cave that is positioned at every row is apart from 35 ~ 40cm.

Three strains in the every cave of the present invention are equilateral triangle and distribute; Compare with the kind method for planting that three strains in the prior art are crowded together; Maximally utilise the space; Rationally utilize soil fertility and light resources, improved the situation of improper ventilation, solved that plant causes rationally utilizing soil fertility, the bad problem of ventilation and penetrating light in the cultivation mode of a cave three strains in the prior art.

And; Two strains in three strains in each cave of every row are arranged in a straight line and near the clearance space of wide row; Remain the clearance space of a strain near narrow row, distribution plant in the narrow row face of land is few like this, and the plant that the wide capable face of land distributes is many; Make the row more reasonable, further improved the utilization and the field ventilation condition of soil fertility, light resources with the above and below ground space utilization between capable.

Description of drawings

Fig. 1 is the distribution map of cotton in the embodiment of the invention.

Embodiment

Below in conjunction with accompanying drawing the embodiment of the invention is done detailed description:

A kind of embodiment of cotton culture method may further comprise the steps:

1) sowing adopts the capable mode of width to sow the wide 80cm of wide every trade; Narrow row line width 40cm, adjacent two row that constitute narrow row adopt wrong bunch planting kind, and the cave, adjacent two cave that is positioned at every row is apart from the every bunch planting kind three nest seeds of 35cm; Three nests are equilateral triangle and distribute; Every nest is broadcast 3 ~ 5 seeds, and nest is apart from 10cm, and perforating is timely earthing epiphragma after planting;

2) field management; The back final singling in time of being unearthed of cotton seedling, every nest keep the healthy and strong cotton seedling of a strain makes that three strains are equilateral triangle in every cave and distributes that spacing in the rows is 10cm in every cave; Two strain being aligneds in three strains in each cave of every row are arranged and near the clearance space of wide row; Remain the clearance space of a strain near narrow row, shown in Figure 1 is the cotton plant distribution situation in cotton field, and wherein 1 is cotton plant.

The cotton culture method also comprises whole ground, fertilising, overlay film, links such as irrigation rationally, results, and these links are prior art; Such as whole ground, fertilising, overlay film, earlier the cotton field deep ploughing to be raked and fertilising when whole ground, per hectare is executed fat 45000～60000 kilograms of farmers'; 150 kilograms in urea, 750 kilograms of superphosphate, 150 kilograms in potassium chloride; Various fertilizer all once apply when whole ground, and the soil moisture conservation of sowing overlay film accomplishes that the Horizon film is flat; Find in the field management step cotton young plant Ye Zhankai by xanthochromia green after, in time put seedling, squaring period, per hectare imposed 75 kilograms in urea; To prosperous long field; The spray mepiquat chloride suppresses, and the full-bloom stage per hectare imposes 300 kilograms in urea, between cotton development stage, in time beats superfluous bud, the pinch point and the limit heart; Take aggregate measures simultaneously, damage by disease and insect such as control cotton bollworm, cotten aphid and yellow fusarium wilt.

Three strains in the every cave of the present invention are equilateral triangle and distribute, and compare with the kind method for planting that three strains in the prior art are crowded together, and maximally utilise the space; Rationally utilize soil fertility and light resources, improved the situation of improper ventilation, two strains in three strains in each cave of every row are arranged in a straight line and near the clearance space of wide row; Remain the clearance space of a strain near narrow row; Narrow row face of land distribution plant is few like this, and the plant that the wide capable face of land distributes is many, makes that the above and below ground space utilization between row and the row is more reasonable; Utilization and the field ventilation condition of soil fertility, light resources have further been improved; Significantly reduce bud drop, the shedding of cotton bolls of cotton, be beneficial to field management, and then realized the high yield target.

In other embodiments of the invention, different with the foregoing description is that wide every trade is wide can also be chosen between 80 ~ 100cm as required; Such as 100cm, 90cm, the narrow row line width can also be chosen between 40 ~ 60cm as required, such as 60cm, 50cm etc.; The cave is apart from can also between 35 ~ 40cm, choosing as required as required; Such as 40cm, 35cm or the like, nest distance and spacing in the rows can also be chosen between 10 ~ 15cm as required, such as 15cm, 12cm etc.Cave of the present invention density: 2083～3175 cave/mus, strain density: 6250～9525 strain/mus.
