CN104380985A - Open-field, high-quality and efficient cultivation technology for lettuce - Google Patents

Abstract

The invention relates to an open-field, high-quality and efficient cultivation technology for lettuce. The technology is characterized by comprising the processes of carrying out soil preparation, ridging, carrying out seedling culture, carrying out transplanting and field planting, managing and the like. According to the technology, the problems of the lettuce that in the traditional cultivation and planting mode, the lettuce is prone to environmental influence and is subjected to irregular seedling emergence and non-uniform seedling size, the seedling delaying period is long after the lettuce is transplanted, the growth of leaf plants is poor, and then, curled and deformed leaves and late-stage sickliness and rot are easily caused are solved; the technology is applicable to the open-field planting of the lettuce.

Description

A kind of romaine lettuce open country High efficiency and high quality cultivation technology

Technical field

The present invention relates to growing vegetables field, is a kind of romaine lettuce open country High efficiency and high quality cultivation technology specifically.

Background technology

At present, romaine lettuce cultivation mode is: adopt traditional native seedbed nursery, do bedding cultivation wholely, broad irrigation is watered, the management mode of artificial trench digging caving & fertilizing, its shortcoming is easily affected by environmently emerged uneven, and large seedling is uneven, after transplanting, seedling-slowing stage is long, leaf strain undergrowth, easily causes leaf rolling deformity, not bag ball, early stage easily bolting, later stage many diseases are rotted.Adverse effect is brought to romaine lettuce High efficiency and high quality cultivation.

Summary of the invention

The present invention is the technical problem solving traditional romaine lettuce cultivation method existence, invents a kind of romaine lettuce open country High efficiency and high quality cultivation technology.

Technical scheme of the present invention, its special character comprises process:

1, whole ground ridging: first plough, next spreads fertilizer over the fields base manure, then revolves ground, ridging, paving irrigate band, covering film, ridge height 16-20 centimetre, row spacing 85-90 centimetre;

2, nursery: the peat composed of rotten mosses, vermiculite, perlite are mixed as matrix in the ratio of 9-3-1, the matrix mixed is loaded 128 hole dishes, and one, every hole seed, then puts into intelligent greenhouse and sets, carry out nursery;

3, transplant planting: when romaine lettuce seedling grows to " three leaves wholeheartedly ", be transplanted to land for growing field crops, every ridge duplicate rows, spacing in the rows 27-30 centimetre, digs cave field planting, and trains real surrounding soil, and transplanting should not be excessively dark, makes base portion just put down with earth's surface, and waters normal root root water in time;

4, water and fertilizer management: keep certain soil moisture content (soil moisture content 65-75%), adopt drip irrigation moisturizing fertile time not enough, 7-10 days pour seedling recovering waters after field planting, on the basis using sufficient base manure, chase after urea 5-8 kilogram (first time topdresses) in conjunction with pour seedling recovering water every mu, enter the rosette stage, to water with cultivated generation, in good time restraining the growth of seedlings, root system is impelled to grow to depth, the restraining the growth of seedlings time should rest in 8-10 days, when lobus cardiacus starts inclusion, restraining the growth of seedlings should be terminated, start watering, fertilizing, every mu chases after N P and K punching fertilising 5-10 kilogram, enter peak of growing season, third time is chased after fertile in conjunction with watering, every mu chases after 5 kilograms, urea, 5 kilograms, potash fertilizer or the fertile 7-10 kilogram of N P and K punching fertilising, to suitably control to water at later stages, and combine spray medicine foliage-spray potassium dihydrogen phosphate, the foliage fertilizers such as calcium chloride or other calcareous fertilisers.

Technique effect

Technique effect of the present invention is, adopts above-mentioned technical scheme, can realize romaine lettuce open country High efficiency and high quality cultivation, this cultivation mode can make seed sprouting fast, neat, even, and after transplanting, slow seedling is fast, and field management water-saving economizes fertile saving of labor, disease pest and weed is few, and output is high, quality better.

Embodiment

1, whole ground ridging: first plough, next spreads fertilizer over the fields base manure, then revolves ground, ridging, paving irrigate band, covering film, ridge height 16-20 centimetre, row spacing 85-90 centimetre;

2, nursery: the peat composed of rotten mosses, vermiculite, perlite are mixed as matrix in the ratio of 9-3-1, the matrix mixed is loaded 128 hole dishes, and one, every hole seed, then puts into intelligent greenhouse and sets, carry out nursery;

3, transplant planting: when romaine lettuce seedling grows to " three leaves wholeheartedly ", be transplanted to land for growing field crops, every ridge duplicate rows, spacing in the rows 27-30 centimetre, digs cave field planting, and trains real surrounding soil, and transplanting should not be excessively dark, makes base portion just put down with earth's surface, and waters normal root root water in time;

4, water and fertilizer management: keep certain soil moisture content (soil moisture content 65-75%), adopt drip irrigation moisturizing fertile time not enough, 7-10 days pour seedling recovering waters after field planting, on the basis using sufficient base manure, chase after urea 5-8 kilogram (first time topdresses) in conjunction with pour seedling recovering water every mu, enter the rosette stage, to water with cultivated generation, in good time restraining the growth of seedlings, root system is impelled to grow to depth, the restraining the growth of seedlings time should rest in 8-10 days, when lobus cardiacus starts inclusion, restraining the growth of seedlings should be terminated, start watering, fertilizing, every mu chases after N P and K punching fertilising 5-10 kilogram, enter peak of growing season, third time is chased after fertile in conjunction with watering, every mu chases after 5 kilograms, urea, 5 kilograms, potash fertilizer or the fertile 7-10 kilogram of N P and K punching fertilising, to suitably control to water at later stages, and combine spray medicine foliage-spray potassium dihydrogen phosphate, the foliage fertilizers such as calcium chloride or other calcareous fertilisers.
