Seedling growing method of cotton by light-substrate mesh bag container

Abstract

The invention relates to a seedling growing method of a cotton by light-substrate mesh bag container, comprising the following steps: manufacturing a cylindrical light-substrate mesh bag container; uprightly arranging the light-substrate mesh bag container on a seedbed; directly pressing a primed cotton seed with the radicle down into the light-substrate mesh bag container to raise the seedling, i.e. inserting a small hole on the light-substrate mesh bag container by a thin stick and then pressing the primed cotton seed with the radicle down; watering with a small amount of water; building a small plastic tunnel to cover the seedbed; and transplanting the cotton seedlings into a field together with the light-substrate mesh bag container when the cotton seedlings grow to a set size. The method has the following advantages: firstly, the method is easily accepted by cotton growers; secondly, the light-substrate mesh bag container can be industrially produced; thirdly, the cotton seedlings grow quicker and stronger, and the planting percent is high; fourthly, lumps are not scattered during transplantation and transportation and are very light, the recovering stage is short, and the survival rate is high; fifthly, the buffering performance of transplantation time is good; sixthly, the cotton seedlings are strong, the recovering stage is short, and the yield is increased; and seventhly, the mesh bag container can be naturally degraded into threads without pollution.

Description

technical field [0001] The invention relates to cotton seedling raising, that is, a method for raising cotton seedlings in a light matrix net bag container. Background technique [0002] Transplanting seedlings is a common habit in cotton production, and cotton seedlings have always been raised in nutrient pots. [0003] Nutrient pot seedling cultivation is actually "earth mass seedling cultivation", which has been used for more than 50 years. Seedling cultivation in nutrient pots can solve the stubble contradiction of cotton production under multi-cropping system; centralized seedling cultivation is conducive to implementing fine management, improving the quality of cotton seedlings, and saving seeds. Nutritive pot seedlings and plastic small arch sheds can be used to raise seedlings in advance, prolong the cotton growth period, and advance the growth process. The proportion of Fuqian peach and Futao increases, the weight of the boll increases, and the cotton production in...

AI Technical Summary

Problems solved by technology

[0006] 1. There are many procedures, many labors, cumbersome, labor-intensive when making bowls and transplanting

[0007] 2. The common problem is that the seedling rate is not high. The average seedling rate is only 50%, rarely more than 70%, and only 10%-20% when it is low; the main reasons are rotten seeds, diseases, insects, and broken nutrition pots

[0008] 3. After transplanting, the slow seedling period is still long

[0014] Technical analysis: 1. It is indeed convenient to raise seedlings without soil in plug trays, but farmers need to purchase various seedling raising materials such as plug trays, vermiculite, river sand, nutrient solution, rooting accelerator, seedling strengthening agent, etc.

[0015] 2. Because the hole in the plug plate is small, the volume is only 1 / 10 of the nutritional pot, the growth space of the upper and lower parts of the cotton seedlings is very limited, and it is difficult to grow healthy seedlings of normal specifications

[0016] 3. Due to the small amount of filling substrate for plug seedling cultivation, it is difficult to manage fertilizer and water during seedling cultivation. Pure vermiculite substrate or adding river sand as substrate at a ratio of 1:1 to reduce substrate cost will easily loosen when taking seedlings for transportation and transplanting. Bare root seedlings The proportion must be relatively large, even if it is combined with rooting promoter treatment, transplanting has higher requirements on soil conditions, especially soil moisture conditions and weather conditions, and the slow seedling period is longer, so it is more difficult to manage after planting

[0027] Technical analysis: 1. It is not easy and portable to make a pool, purchase seedling trays, substrates, and prepare nutrient solutions;

[0028] 2. Because the holes are small and dense, it is difficult to cultivate robust cotton seedlings that can reach the transplanting specifications;

[0029] 3. In the way of floating seedlings, the humidity of the substrate is relatively high, and the formed root system must have the characteristics of wet rooting, poor stress resistance, poor adaptability to dry land conditions, long transplanting slow seedling period, and low survival rate

However, the buffering performance of the transplanting time is not good. The so-called "unwaiting time for seedlings" has not been able to effectively shorten the slow seedling period after transplanting, and has not been able to achieve scattered and generally extensive land conditions (plank land), impossible The high survival rate of transplanting under controlled weather conditions and extensive transplanting management conditions failed to realize the simplification of post-planting management links
