Description:

The technical term for watering is IRRIGATION. It is the application of water to plants either outside or under glass. Of course it is especially important under glass because there is no natural rainfall inside a greenhouse. The most specialized methods of irrigation have evolved under glass where the application needs to be both efficient, accurate, and often automatic to save on labour.WATER OF GREENHOUSE CROPS1. WATERING CAN. Can be used for both watering and feeding. It is a reasonably accurate and flexible method, but is also slow and costly on a large scale.HOSE PIPE. This also can be used for watering and feeding, and is a flexible and accurate method in skilled hands. On the other hand it is costly in terms of manpower and can damage the soil structure unless the pressure is controlled.SPRAYLINES. These can be either low level at the height of the crop, or slung above the crop on supports hanging from the greenhouse roof. Overhead spraylines have a wider throw than low level spraylines, and so fewer nozzles are required. Both systems can be used for watering or feeding. Overhead spraylines tend to overlap, thus producing variations in the application rate. High pressure, and high flow rates are required.Low-level spraylines are useful because they can be set up to water the whole bed by using a larger nozzle size. The throw can be variable because nozzle delivery overlaps; this tends to produce a variable application rate over the whole area; this problem is also noted above for overhead spraylines.Types of sprayline NOZZLE I) Anvil mist nozzle ii) Pin-jet iii) Rotary sprinklerThe watering equipment mentioned above can be used on outdoor crops as well; where nozzles such as the pin-jet and anvil mist nozzle are used outside, there may be problems with excessive drift due to the wind blowing the fine water droplets, so it would be advisable to use a nozzle type which produces larger coarser droplets which are not moved so easily in the wind. The rotary sprinkler would be useful here (see iii above).SOME OTHER WATERING EQUIPMENT1. A small oscillating spray unit for use on a lawn or vegetables e.g ‘The Lawn Queen.2. Static spraylines with the nozzles arranged to give a cover either side of the pipes in the shape of a rectangle.3. A pressure operated oscillating sprayline operated by a double action piston mechanism.The area covered is rectangle shaped; this system usually operates off 25 mm (1 inch) pipe, and is a low pressure high volume system.4. ROTARY SPRINKLER HEAD. Water is forced out from the nozzle and hits the breaker plate. This breaks up the water droplets and deflects the plate. The plate rebounds against the spring thus rotating the head in a series of short jerky movements. The spray pattern is circular.5. LAYFLAT TUBING: Can be used outside or under protection. Consists of 50mm (2in) polythene tubing. Water passes out through pin-pricks in the tube.6. SEEPHOSE. This consists of stitched polythene pipe. Water passes out through the stitching. With these two systems, the area covered is a long narrow strip or row. These two techniques are called trickle irrigation.ADVANTAGES OF TRICKLE IRRIGATION1. Useful for tunnels, propagating frames or beds.2. Slow and accurate application of water.3. Soil structure is not damaged.Filed Under: Flower GardeningHAND TOOLS IN THE GARDENPosted on September 23, 2015 by Rupert Foxton-Smythe 0 CommentsThere are a wide range of hand tools used in the garden for a variety of different purposes. Among the most common are the digging fork, and its smaller relative the border fork. Other commonly used tools are the RAKE, HOE, TROWEL, HAND AND EDGING SHEARS, SECATEURS, SHOVEL, LONG ARMED PRUNERS. The maintenance of all Continue ReadingFiled Under: Flower GardeningCROP CULTIVATION EQUIPMENT MAINTENANCEPosted on September 23, 2015 by Rupert Foxton-Smythe 0 CommentsThere are two types of cultivation broadly used in crop production. The first is called PRIMARY CULTIVATION. This is where, if the operation is carried out correctly, the soil is deeply disturbed and inverted so that soil from lower levels is exposed to the surface. Thus digging is a form of primary cultivation, as is Continue ReadingFiled Under: Flower GardeningPOWER UNITS AND GARDEN MACHINERY ELEMENTSPosted on September 23, 2015 by Rupert Foxton-Smythe 0 CommentsThis post refers to the use and care of garden tools, machines and appliances. Clearly, this is a very large topic and the kind of questions it raises might range from the selection of a spade, fork or hoe, to the use, care and maintenance of a small garden tractor. The principal factor in the Continue ReadingFiled Under: Flower GardeningTURF PESTSPosted on September 23, 2015 by Rupert Foxton-Smythe 0 CommentsINTRODUCTION Groundsmen in this country are relatively fortunate in having a limited number of pests which cause serious damage to turf. The following can be considered to be the major pests affecting turf grass:- Worms Leatherj ackets Moles Less common pests – Fever fly Frit fly Also some other miscellaneous insects and animals, e.g. bitch Continue ReadingFiled Under: Flower GardeningTURF DISEASESPosted on September 23, 2015 by Rupert Foxton-Smythe 0 CommentsCAUSES OF DISEASE a) Environmental Any factor causing a lowering of growth and loss of colour:- low fertility weather conditions. b) Biological Organisms that attack living plants and cause disease are pathogens, and generally for turf culture purposes it can be assumed that, fungi are the main agents responsible for causing diseases. Other alternative agents Continue ReadingFiled Under: Flower GardeningUSING KNAPSACK SPRAYERSPosted on September 22, 2015 by Rupert Foxton-Smythe 0 Comments1. PUT ON PROTECTIVE CLOTHING Some chemicals are dangerous, and must be handled with care. The necessary protective clothing is specified on the manufacturers’ label, and should always be worn as indicated. Poisoning can be caused by contact with the skin, as well as by swallowing, breathing in vapour, spray mist or dust. It is Continue ReadingFiled Under: Flower GardeningINTRODUCTION TO ADVANCED WEED CONTROLPosted on September 22, 2015 by Rupert Foxton-Smythe 0 CommentsA weed is a plant that is growing in the wrong place. This definition can apply to all plants and all situations. Even a precious orchid may be regarded as a weed if it grows in the wrong place. Herbicide treatments are applied as a means of solving weed problems efficiently, either as total herbicides Continue ReadingFiled Under: Flower GardeningSOME COMMON WEEDS OF LAWNSPosted on September 22, 2015 by Rupert Foxton-Smythe 0 CommentsDAISY: Bellis perennis (family Compositae) General points One of the commonest and most easily recognised weeds in lawns. Its prostrate habit is relatively unaffected by mowing and the spoon-shaped leaves smother, or can smother finer grasses to the extent of taking over large areas in a neglected lawn. The fibrous root system makes it a Continue ReadingFiled Under: Flower GardeningMEADOW TURFPosted on September 22, 2015 by Rupert Foxton-Smythe 0 CommentsThe objectives of having an area of meadow turf may include:- 1. A wild garden area to enrich the senses with the ideals of conservation. A diversity of wild flowers and insects supporting more wild bird species (like goldfinches feeding off the grass seed heads). 2. Demanding less labour to manage and control the land.
