2.1 技术简介

技术定义:

Application of cattle urine through drip irrigation technology to provide constant flow of fertiliser to bitter gourd

2.2 技术的详细说明

说明:

Bitter gourd vegetables fetch a high price in the off-season and respond well if grown with drip irrigation. This crop is planted in December/January and harvested from May through to July/August. The growing period mainly falls in the driest period of the year and therefore requires irrigation.
In addition to water, the plants need fertiliser to ensure healthy growth and good production. Nitrogen is the most important macronutrient for plants and high crop productivity can only be achieved if sufficient nitrogen is available. Nitrogen is also the most limiting nutrient in most areas of Nepal’s midhills. Traditionally farmers applied farmyard manure; but in many places this is being supplemented or entirely replaced by inorganic fertiliser, mainly urea. However, fertiliser prices have increased substantially in recent years and this type of fertiliser is often not available in sufficient quantities in areas away from the roadheads. At the same time cultivation practices are intensifying with greater cropping intensities and more nutrient demanding crops as local varieties are replaced by hybrids and new crops are introduced. This can easily lead to nutrient mining and soil fertility decline unless there is an equivalent increase in inorganic or mineral fertilisation.
Cattle urine is a viable alternative to mineral fertiliser; it is nitrogen rich. The urine is collected in improved cattle sheds (fact sheet on urine collection QT NEP1). For constant fertiliser application and to reduce the water requirement, the collected urine can be added to the irrigation water in the drip irrigation tanks (fertigation). Farmers who have tried this say it has increased the yield of bitter gourd and other cash crops, in some cases by as much as 100%. Other crops that can be grown using drip irrigation with a water-urine mixture are cauliflower, cucumber, and other types of gourd.

农田

• 一年一作

年作 - 具体指明作物:

• 蔬菜 - 香瓜、南瓜、南瓜或葫芦

注释:

Major land use problems (compiler’s opinion): Intensifying cultivation practices with either 1) inadequate application of fertilisers leading to a decline in soil fertility and the mining of soil nutrients or 2) application of too much fertiliser causing environmental problems through excessive leaching, and losses of fertiliser in surface runoff and consequent eutrophication or nitrification of streams, ponds, or groundwater. Also, irrigation water is in short supply during 6 to 8 months of the year. Fertigation allows about 20 to 30% of the irrigation water to be replaced by urine.

4.1 该技术的技术图纸

技术规范（与技术图纸相关）:

The following setup was used in Iman Singh Basnet’s fi eld:
- two drip irrigation sets: one set with
8 lines, one with 4 lines
- a 200 l plastic drum
- 20 bitter gourd plants per line with
1.5m spacing between lines
- approximate area covered: 200m2
Note that the drum was not delivered with the drip irrigation set. Mr Basnet uses the same drum for irrigating other crops where drip irrigation is not feasible, in which case he connects a pipe with a rose to the drum.

Technical knowledge required for field staff / advisors: low

Technical knowledge required for land users: low

Main technical functions: supplementary irrigation, constant and slow supply of nutrients, increase in soil fertility & increase in soil productivity

Secondary technical functions: pest control

5.6 应用该技术的土地使用者的特征

说明土地使用者的其他有关特征:

Off-farm income specification: In most farm households, off-farm income plays at least a minor and increasingly a major role. Occasional opportunities for off-farm income present themselves in the form of daily labour wages. Some households’ members receive regular salaries, whilst an increasing number of Nepalis are working in India, the Middle East, Malaysia, and elsewhere and sending remittance incomes home.

注释:

The high cost of mineral fertiliser and the high price that bitter gourd fetches means that the establishment costs are soon recovered. In the long-term, a major reduction in fertiliser costs and improved income leads to increased benefits.
