A recent visit to the cassava fields found a strange image: some farm-based vines grow crazy and have little potatoes, and some of the earth's infested with pests and pests. The problem is in planting the “first four steps” — the “gold foundation period” that determines the production of the cassava — and doing it right, with a lot of potatoes, it's impossible to fix it later! I'm not gonna throw it out
One, the “four deadly flows” of potato cultivation, 90% of the newcomers have stepped on it
No-drying direct rise: soil sheeting, “crowding to deformity”
As a result, 80 per cent of the production of potatoes was found to be “curved” “fibres”. The farmman threw a shovel at the top of the earth: "the ground is full of fists, the potatoes have no space to expand!"
The bottom fertilizers are used only in fertilizer: the vines fail early and the potatoes are short
A cooperative in hebei uses urea alone to produce urea, with pre-vegetal vines that are so long, that they fall yellow, with an acre production of 2,000 pounds less than normal plots. Old farmer's summary: "fertilizer burns roots and lacks nutrients. It's like eating rice without food
3. Planting leaks: white vines don't make potatoes
New hands often make mistakes: only one or two knots are planted, and the vines grow long, but the ground does not have its roots. A realistic assessment of the farmers in shandong: three cents of cassava three to five, one knot of seedling only one, and the chips are as small as eggs
Do not pour critical water after planting: miss the potato gold period
After a drought, li, an old farmer in henan, did not water, and 25 days later the vine grew 10 centimetres long, cutting off the soil: the fresh roots dried up, and the potatoes didn’t start. “this water is equivalent to a ‘generative potion’, which is poured 10 days later, with less than half of the output!” the farmer said。
Ii. High production of red potatoes, "first four steps" dialysis. Just do it
First step: deep-sliding — “finching bones” for sweet potatoes
- depth of 30-40 cm tillage (to break the plough floor with a large tiller)。
- best timing: morning tilling, 2-3 days in the sun, killing eggs and fungus。
- comparative data: 50 per cent improvement in the air penetration of deep and shallow plots and 30 per cent reduction in the rate of red potatoes decay in the later stages
Second step: application of bottom fertilizer + rise — installation of a “nutrient ward”
Gold formulation:
- basic manure: 80 kg per acre of high potassium (15-5-20) compound fertilizer + 20 kg per acre of potassium sulphate (concentrated seedling)。
- upgrading programme: 500 pounds of decomposed goat dung + 100 pounds of biobacterium (remediation of soil, prevention of serious disease)。
- insect resistance: 4 kg/acre of granule agent (and tillage after application, special treatment, platinum)。
Surgery:
- double rows: 80 centimetres wide, 30 centimetres high and 30 centimetres between two lines (more than 8,000 kg of acre for fertile plots)。
- single row: 60 cm wide and 25 cm high (suitable for hill blocks, easy to drain)。
Step three: shifting cultivation - the nodes are key
Insert the three principles:
- section 3-5 on earth: 3-5 in central seedlings, with only 2-3 leaves on top。
- depth 3-5 centimetres: too deep, too light to dry, and up to 5 centimetres of sand。
- pumping of the root water: “back root water” immediately after planting can be used to boost the emergence of new roots by using a 500-fold corrosive acid water。
Step four: 20 days after planting, watering with “chip” - awakening reproductive growth
- timing of water: 20 to 25 days after planting (when the potato enters the trough formation period)。
- watering methods: watering along a ditch, wetting 20 centimetres of the earth and avoiding heavy flooding leading to soil slabs。
- production secret: 5 kg per acre (10-5-30) of potassium soluble fertilizer per acre during watering, promoting the transfer of nutrients from roots to chips。
3. “shortage time difference” in different regions, no more “one size fits all”
1. Southern region (gangdong, fujian)
- potatoes: growed in february-march, using a “square planting” method (more earthfalls) to adapt to high temperature and rain。
- potatoes: planted in june-july, rising to 35 centimetres, resistant to watery potatoes。
2. North (sundong, henan)
- potatoes: cultivated late in april, then covered the membrane (5°c to increase the temperature of the ground, 15 days earlier)。
- potatoes: after the harvest of wheat in early june, the seed was taken and the “pre-cooked chicken species” (e. G., watermelon red) were selected to avoid pre-cooking。
