There are many rice fields and pit ponds in rural areas that have been abandoned for long periods of time because they cannot be used effectively
I. Tunnel rehabilitation
1. To ensure that pond water levels are consistent and that the land is even, the bottom of the pond needs to be levelled。
2. Leakproof ponds where leaks are severe or where local water resources are scarce shall be protected against leaks at the bottom of the pond. It would be preferable to use a permeable membrane dedicated to the pond for laying, and to refill the high-quality soil 30 cm after completion. Due to the high cost of impermeable membrane laying, the pond is free of impermeable membranes, to the extent possible, in cases where the pond is in good water performance。
Ii. Options
According to the fact that the depth of the water is divided into shallow and deep waters, the depth of the water is less than 50 centimetres (e. G. 3735 centimetres, pearls, giants, flowers, etc.) and the depth of the water is 50 to 150 centimetres (e. G. Snow lotion, florist, lotion one, hybrids, etc.) and 150 to 220 centimetres require the choice of ultra-suffering。
Lsd can be classified according to taste (high starch content) and brilliance (low starch content) in the south, which likes to grow 3735 lactation species, large, and so forth, and in the north, which likes to grow spicy seeds。
Iii. Melin production technology
1- density: 400-500 pounds per acre, with an appropriate increase in cultivation if water guns are used. Cultivation density can be planned according to the size of the seed, with a special seed of about 1. 5 to 2 pounds, with a distance of 2. 5 and 1. 1 metres, respectively。
Potassium sulphate per acre before planting combined fat 80-100 pounds, potassium sulphate per acre during flower season. The compound fat 80-100 pounds, and potassium sulphate per acre during the lumbering period is 100-120 pounds. Note that urea, potassium chloride and high nitrogen compound fertilizer are not subject to application, which would seriously affect the production of lush。
3. Maintain appropriate water levels to protect against water scarcity or flooding; once the leaves rise, they may be placed at the end of one to three acres of grassfish, depending on the amount of beak and weed。
Iv. Efficiencies of lotus
1 cost 400 yuan/acre, 800 yuan/acre for seeding, 600 yuan/acre for fertilizer, 300 yuan/acre for labour, 200 yuan/acre for other, for a total of 2300 yuan/acre。
The harvest can begin after mid-fall and last until around the following year. Under the conditions of shallow water cultivation and proper management, each acre can yield 8,000 to 10,000 pounds of fruit, of which the main output is 5,000 to 6,000 pounds. The cost of water gun mining is us$ 1,500 to 1800 per acre and us$ 2,500 to 3,000 per acre by a waterman。
Prices vary widely between north and south and between east and west, with wholesale prices ranging from 0. 8 to 2. 2 pounds. Wholesale prices amount to 7,500 to 9,000 yuan per acre, with a net profit of 2,300 to 3700 yuan per acre, excluding 2,300 yuan for planting and 3,000 yuan for digging。
