Abstract
The invention provides a method for adjusting and controlling soil humidity during a carrot planting process, which comprises the steps of sprouting in a relatively moist soil humidity, promoting roots to grew deep in a slightly dry soil humidity, exercising seedling in a relatively dry soil humidity, controlling overgrowth in a slightly dry soil humidity, balancing the roots in a slightly moist soil humidity and promoting quality in a moist soil humidity. According to the characteristics of different growing phases during the carrot planting process, through the dry-wet adjusting and controlling method provided by the invention, the water supplying quantity is adjusted, the sizes of fleshy roots of carrots are controlled, the proportion of the carrots of 180 to 330g is improved, and the improvement of the output of carrot per mu is facilitated.
Description
[technical field]
The present invention relates to the soil moisture regulate and control method in a kind of agricultural planting technique, be specifically related to the soil moisture regulate and control method in a kind of carrot planting process, belong to field of agricultural cultivation.
[background technology]
The edible part of carrot is fertile tender meat taproot, and its kind is a lot, by color and luster can be divided into red, yellow, white, purple etc. several.What China's cultivation was maximum is red, white two kinds.Market survey finds, fleshy root is that elongated cylindrical, the blunt circle of tail end, the carrot of quality between 180g-330g are most favored by customers, and sales volume is large, price is high.The carrot of the blunt circle of elongated cylindrical, tail end sells lover, easy cleaning, the carrot size to fit of 180g-330g, in current general family, a meal is just enough, too large, a meal is eaten up, and easily causes waste, too little, one meal one is not enough, and read fortune and nutrition are also poor, and therefore weight is one of best possible merchandise proterties of carrot between 180g-330g.
Carrot belongs to half cold resistance, is long-day plant, and happiness is felt nice and cool to the weather of gentleness, and avoid flood and be afraid of stain, rotten of the easiest ponding, responsive to soil moisture, overdrying can affect the growth of fleshy root, and make it to diminish, quality is coarse, and easily produces the chaff heart; If antecedent moisture is too much, aerial growth is excessively prosperous, can affect the growth of taproot, even produces fork root; If later stage excess moisture, can make fleshy root rough coat, secondary root is given prominence to.According to the soil moisture in the sprinkling method regulation and control carrot planting process in current agricultural industry criteria, easily there is the problems such as survival rate is low, fleshy root size is uneven.
[summary of the invention]
The object of this invention is to provide a kind of can control carrot fleshy root size, improve the carrot ratio between 180g-330g and improve the soil moisture regulate and control method of carrot per mu yield.
For achieving the above object, technical scheme of the present invention is as follows:
Soil moisture regulate and control method in carrot planting process, comprises the following steps:
(1) comparatively wetly to emerge: sowing same day, first time water spraying time be 30-40 minutes, make soil moisture reach 70%-80%, once, by the 5-10 day, every day sprayed twice in later spray every day, each spray 25 minutes, and soil moisture reaches more than 80%;
(2) slightly dry short root is profound: within the 11st day, to growing true leaf, once, soil moisture is 40% to two days water sprays;
(3) more dry hardening: grow the 7-10 after true leaf days and do not spray water;
(4) slightly dry control overgrowing: 35-74 days, moisture is not too many, and every spray in a 4 days water, each water spraying time is 30-60 minute;
(5) slightly wet neat root: the 75th day-90 days, output be increased, every spray in a 3 days water, each water spraying time is 90-150 minute;
(6) moistening upgrading: from the 91st day to results, every day sprays water, and makes soil moisture remain on 62%-72%.
Preferably, after planting 5-10 days in described step (1), sprays water twice every day, respectively sprays once in the morning respectively with afternoon.
Preferably, described step (3) is loosened the soil in conjunction with intertillage, and concrete grammar is: after growing true leaf, draws ditch to loosen the soil and gets sun, and ditch dark 6 ㎝, shines after 7-10 days and recovers water spray.
Preferably, in described step (4), the time of each water spray is preferably 45 minutes.
Preferably, in described step (5), the time of each water spray is preferably 120 minutes.
Carrot is the seeding stage from being seeded into the 10th day, comparatively wets and emerges, and is conducive to the germination rate improving seed; From the 11st day to before growing true leaf, be in the moisture that slightly dry state can promote root absorption deep soil, thus promote that carrot root is profound; After growing true leaf, control seedling and be in more dry state, extraneous unsuitable environmental condition can be adapted to rapidly, improve the resistance of seedling; Within after planting 35-74 days, be leaf growth animated period during this period of time, suitably control soil moisture and aerial growth can be prevented excessively prosperous; Within after planting 75 days-90 days, be carrot fleshy root expanding stage, water requirement is large, and moisture multipotency promotes the root of the tail of carrot to look blunt circle, grows into elongated cylindrical, improves the aesthetics of fleshy root; Before after planting 90 days to results, keep soil gently moistening, anti-crack arrest root, to improve carrot quality.
Beneficial effect of the present invention is: according to the characteristic of Different growth phases in carrot planting process, by dry wet regulate and control method of the present invention, regulate output, control the size of carrot fleshy root, improve the carrot proportion of 180g-330g, and be conducive to the per mu yield improving carrot.Test proves, compared with sprinkling method of the prior art, adopt soil moisture regulate and control method in carrot planting process of the present invention to control output, the carrot proportion that the per mu yield of carrot can improve 21.4%, 180g-330g can improve 17.4%.
